1. Name Of The Medicinal Product



Ramipril 10mg Capsules


2. Qualitative And Quantitative Composition



Each hard capsule contains ramipril 10 mg.



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Hard Capsules. Size 4 with blue cap/white body imprinted with 'R' on cap and '10' on body. Contains white to off-white granular powder.



4. Clinical Particulars



4.1 Therapeutic Indications



-Ramipril Capsules are indicated for the treatment of mild to moderate hypertension.



- Cardiovascular prevention: reduction of cardiovascular morbidity and mortality in patients with:



o manifest atherothrombotic cardiovascular disease (history of coronary heart disease or stroke, or peripheral vascular disease) or



o diabetes with at least one cardiovascular risk factor (see section 5.1).



- Treatment of renal disease:



o Incipient glomerular diabetic nephropathy as defined by the presence of microalbuminuria,



o Manifest glomerular diabetic nephropathy as defined by macroproteinuria in patients with at least one cardiovascular risk factor (see section 5.1),



o Manifest glomerular non diabetic nephropathy as defined by macroproteinuria



- Treatment of symptomatic heart failure.



- Secondary prevention after acute myocardial infarction: reduction of mortality from the acute phase of myocardial infarction in patients with clinical signs of heart failure when started > 48 hours following acute myocardial infarction.



4.2 Posology And Method Of Administration



Ramipril Capsules should be taken with a glass of water. It is recommended that ramipril is taken each day at the same time of the day.



Ramipril can be taken before, with or after meals, because its absorption is not affected by food (see section 5.2). Ramipril capsules has to be swallowed with liquid. It must not be chewed or crushed.



Dosage and Administration:



Adults



Diuretic-Treated patients



Hypotension may occur following initiation of therapy with ramipril; this is more likely in patients who are being treated concurrently with diuretics. Caution is therefore recommended since these patients may be volume and/or salt depleted.



If possible, the diuretic should be discontinued 2 to 3 days before beginning therapy with ramipril (see section 4.4).



In hypertensive patients in whom the diuretic is not discontinued, therapy with ramipril should be initiated with a 1.25 mg dose. Renal function and serum potassium should be monitored. The subsequent dosage of ramipril should be adjusted according to blood pressure target.



Hypertension



The dose should be individualised according to the patient profile (see section 4.4) and blood pressure control.



Ramipril may be used in monotherapy or in combination with other classes of antihypertensive medicinal products.



Starting dose



Ramipril should be started gradually with an initial recommended dose of 2.5 mg daily.



Patients with a strongly activated renin-angiotensin-aldosterone system may experience an excessive drop in blood pressure following the initial dose. A starting dose of 1.25 mg is recommended in such patients and the initiation of treatment should take place under medical supervision (see section 4.4).



Titration and maintenance dose



The dose can be doubled at interval of two to four weeks to progressively achieve target blood pressure; the maximum permitted dose of ramipril is 10 mg daily. Usually the dose is administered once daily.



Cardiovascular prevention



Starting dose



The recommended initial dose is 2.5 mg of ramipril once daily.



Titration and maintenance dose



Depending on the patient's tolerability to the active substance, the dose should be gradually increased. It is recommended to double the dose after one or two weeks of treatment and - after another two to three weeks - to increase it up to the target maintenance dose of 10 mg ramipril once daily.



See also posology on diuretic treated patients above.



Treatment of renal disease



In patients with diabetes and microalbuminuria:



Starting dose:



The recommended initial dose is 1.25 mg of ramipril once daily.



Titration and maintenance dose



Depending on the patient's tolerability to the active substance, the dose is subsequently increased. Doubling the once daily dose to 2.5 mg after two weeks and then to 5 mg after a further two weeks is recommended.



In patients with diabetes and at least one cardiovascular risk



Starting dose:



The recommended initial dose is 2.5 mg of ramipril once daily.



Titration and maintenance dose



Depending on the patient's tolerability to the active substance, the dose is subsequently increased. Doubling the daily dose to 5 mg ramipril after one or two weeks and then to 10 mg ramipril after a further two or three weeks is recommended. The target daily dose is 10 mg.



In patients with non- diabetic nephropathy as defined by macroproteinuria 3 g/day.



Starting dose:



The recommended initial dose is 1.25 mg of ramipril once daily.



Titration and maintenance dose



Depending on the patient's tolerability to the active substance, the dose is subsequently increased. Doubling the once daily dose to 2.5 mg after two weeks and then to 5 mg after a further two weeks is recommended.



Symptomatic heart failure



Starting dose



In patients stabilized on diuretic therapy, the recommended initial dose is 1.25 mg daily.



Titration and maintenance dose



Ramipril should be titrated by doubling the dose every one to two weeks up to a maximum daily dose of 10 mg. Two administrations per day are preferable.



Secondary prevention after acute myocardial infarction and with heart failure



Starting dose



After 48 hours, following myocardial infarction in a clinically and haemodynamically stable patient, the starting dose is 2.5 mg twice daily for three days. If the initial 2.5 mg dose is not tolerated a dose of 1.25 mg twice a day should be given for two days before increasing to 2.5 mg and 5 mg twice a day. If the dose cannot be increased to 2.5 mg twice a day the treatment should be withdrawn.



See also posology on diuretic treated patients above.



Titration and maintenance dose



The daily dose is subsequently increased by doubling the dose at intervals of one to three days up to the target maintenance dose of 5 mg twice daily.



The maintenance dose is divided in 2 administrations per day where possible.



If the dose cannot be increased to 2.5 mg twice a day treatment should be withdrawn. Sufficient experience is still lacking in the treatment of patients with severe (NYHA IV) heart failure immediately after myocardial infarction. Should the decision be taken to treat these patients, it is recommended that therapy be started at 1.25 mg once daily and that particular caution be exercised in any dose increase.



Special populations



Patients with renal impairment



Daily dose in patients with renal impairment should be based on creatinine clearance (see section 5.2):



- if creatinine clearance is



- if creatinine clearance is between 30-60 ml/min, it is not necessary to adjust the initial dose (2.5 mg/day); the maximal daily dose is 5 mg;



- if creatinine clearance is between 10-30 ml/min, the initial dose is 1.25 mg/day and the maximal daily dose is 5 mg;



- in haemodialysed hypertensive patients: ramipril is slightly dialysable; the initial dose is 1.25 mg/day and the maximal daily dose is 5 mg; the medicinal product should be administered few hours after haemodialysis is performed.



Dosage in hepatic impairment (see section 5.2):



In patients with impaired liver function the metabolism of the parent compound ramipril, and therefore the formation of the bioactive metabolite ramiprilat, is delayed due to a diminished activity of esterases in the liver, resulting in elevated plasma ramipril levels. Treatment with ramipril should therefore be initiated under close medical supervision in patients with impaired liver function and the maximum daily dose is 2.5 mg ramipril.



Elderly: Initial doses should be lower and subsequent dose titration should be more gradual because of greater chance of undesirable effects especially in very old and frail patients. A reduced initial dose of 1.25 mg ramipril should be considered.



Children: Ramipril has not been studied in children and adolescents below 18 years of age, and therefore use in this age group is not recommended.



4.3 Contraindications



Hypersensitivity to ramipril or any of the excipients or any other ACE (Angiotensin Converting Enzyme) inhibitors (see section 6.1).



History of angioneurotic oedema(hereditary, idiopathic or due to previous angioedema with ACE inhibitors or AIIRAs).



Extracorporeal treatments leading to contact of blood with negatively charged surfaces (see section 4.5)



Significant bilateral renal artery stenosis or renal artery stenosis in a single functioning kidney.



Second and third trimesters of pregnancy (see sections 4.4 and 4.6).



Ramipril must not be used in patients with hypotensive or haemodynamically unstable states.



4.4 Special Warnings And Precautions For Use



Special populations



-Pregnancy: ACE inhibitors such as ramipril, or Angiotensin II Receptor Antagonists (AIIRAs) should not be initiated during pregnancy. Unless continued ACE inhibitor/AIIRAs therapy is considered essential, patients planning pregnancy should be changed to alternative antihypertensive treatments which have an established safety profile for use in pregnancy. When pregnancy is diagnosed, treatment with ACE inhibitors/AIIRAs should be stopped immediately, and, if appropriate, alternative therapy should be started (see sections 4.3 and 4.6).



-Patients at particular risk of hypotension



Patients with strongly activated renin-angiotensin-aldosterone system



Patients with strongly activated renin-angiotensin-aldosterone system are at risk of an acute pronounced fall in blood pressure and deterioration of renal function due to ACE inhibition, especially when an ACE inhibitor or a concomitant diuretic is given for the first time or at first dose increase.



Significant activation of renin-angiotensin-aldosterone system is to be anticipated and medical supervision including blood pressure monitoring is necessary, for example in:



- patients with severe hypertension



- patients with decompensated congestive heart failure



- patients with haemodynamically relevant left ventricular inflow or outflow impediment (e.g. stenosis of the aortic or mitral valve)



- patients with unilateral renal artery stenosis with a second functional kidney



- patients in whom fluid or salt depletion exists or may develop (including patients with diuretics)



- patients with liver cirrhosis and/or ascites



- patients undergoing major surgery or during anaesthesia with agents that produce hypotension.



Generally, it is recommended to correct dehydration, hypovolaemia or salt depletion before initiating treatment (in patients with heart failure, however, such corrective action must be carefully weighed out against the risk of volume overload).



-Transient or persistent heart failure post MI



-Patients at risk of cardiac or cerebral ischemia in case of acute hypotension



The initial phase of treatment requires special medical supervision.



-Elderly patients



See section 4.2.



- Surgery



It is recommended that treatment with angiotensin converting enzyme inhibitors such as ramipril should be discontinued where possible one day before surgery.



-Monitoring of renal function



Renal function should be assessed before and during treatment and dosage adjusted especially in the initial weeks of treatment. Particularly careful monitoring is required in patients with renal impairment (see section 4.2). There is a risk of impairment of renal function, particularly in patients with congestive heart failure or after a renal transplant.



-Angioedema :



Angioedema has been reported in patients treated with ACE inhibitors including ramipril (see section 4.8).



In case of angioedema, ramipril must be discontinued.



Emergency therapy should be instituted promptly. Patient should be kept under observation for at least 12 to 24 hours and discharged after complete resolution of the symptoms.



Intestinal angioedema has been reported in patients treated with ACE inhibitors including ramipril (see section 4.8). These patients presented with abdominal pain (with or without nausea or vomiting).



-Anaphylactic reactions during desensitization:



The likelihood and severity of anaphylactic and anaphylactoid reactions to insect venom and other allergens are increased under ACE inhibition. A temporary discontinuation of ramipril should be considered prior to desensitization.



-Hyperkalaemia:



Hyperkalaemia has been observed in some patients treated with ACE inhibitors including ramipril. Patients at risk for the development of hyperkalaemia include those with renal insufficiency, age (> 70 years), uncontrolled diabetes mellitus, or those using potassium salts, potassium retaining diuretics and other plasma potassium increasing active substances, or conditions such as dehydration, acute cardiac decompensation, metabolic acidosis. If concomitant use of the above mentioned agents is deemed appropriate, regular monitoring of serum potassium is recommended (see section 4.5).



Neutropenia/agranulocytosis:



Neutropenia/agranulocytosis, as well as thrombocytopenia and anaemia, have been rarely seen and bone marrow depression has also been reported. It is recommended to monitor the white blood cell count to permit detection of a possible leucopoenia. More frequent monitoring is advised in the initial phase of treatment and in patients with impaired renal function, those with concomitant collagen disease (e.g. lupus erythematosus or scleroderma), and all those treated with other medicinal products that can cause changes in the blood picture (see sections 4.5 and 4.8).



Ethnic differences



ACE inhibitors cause higher rate of angioedema in black patients than in non black patients.



As with other ACE inhibitors, ramipril may be less effective in lowering blood pressure in black people than in non black patients, possibly because of a higher prevalence of hypertension with low renin level in the black hypertensive population.



Cough



Cough has been reported with the use of ACE inhibitors. Characteristically, the cough is nonproductive, persistent and resolves after discontinuation of therapy. ACE inhibitor-induced cough should be considered as part of the differential diagnosis of cough.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Contraindicated combinations



Extracorporeal treatments leading to contact of blood with negatively charged surfaces such as dialysis or haemofiltration with certain high-flux membranes (e.g. polyacrylonitril membranes) and low density lipoprotein apheresis with dextran sulphate due to increased risk of severe anaphylactoid reactions (see section 4.3). If such treatment is required, consideration should be given to using a different type of dialysis membrane or a different class of antihypertensive agent.



Precautions for use



Potassium salts, heparin, potassium-retaining diuretics and other plasma potassium increasing active substances (including Angiotensin II antagonists, trimethoprim, tacrolimus, ciclosporin): Hyperkalaemia may occur, therefore close monitoring of serum potassium is required.



Antihypertensive agents (e.g. diuretics) and other substances that may decrease blood pressure (e.g.nitrates, tricyclic antidepressants, anaesthetics, acute alcohol intake, baclofen, alfuzosin, doxazosin, prazosin, tamsulosin, terazosin): Potentiation of the risk of hypotension is to be anticipated (see section 4.2 for diuretics)



Vasopressor sympathomimetics and other substances (e.g. isoproterenol, dobutamine, dopamine, epinephrine) that may reduce the antihypertensive effect of ramipril: Blood pressure monitoring is recommended.



Allopurinol, immunosuppressants, corticosteroids, procainamide, cytostatics and other substances that may change the blood cell count: Increased likelihood of haematological reactions (see section 4.4).



Lithium salts: Excretion of lithium may be reduced by ACE inhibitors and therefore lithium toxicity may be increased. Lithium level must be monitored.



Antidiabetic agents including insulin: Hypoglycaemic reactions may occur. Blood glucose monitoring is recommended.



Non-steroidal anti-inflammatory drugs and acetylsalicylic acid: Reduction of the antihypertensive effect of ramipril is to be anticipated. Furthermore, concomitant treatment of ACE inhibitors and NSAIDs may lead to an increased risk of worsening of renal function and to an increase in kalaemia.



4.6 Pregnancy And Lactation



Pregnancy:





The use of ACE inhibitors is not recommended during the first trimester of pregnancy (see section 4.4). The use of ACE inhibitors is contraindicated during the second and third trimester of pregnancy (see sections 4.3 and 4.4).



Epidemiological evidence regarding the risk of teratogenicity following exposure to ACE inhibitors during the first trimester of pregnancy has not been conclusive; however a small increase in risk cannot be excluded. Unless continued ACE inhibitor therapy is considered essential, patients planning pregnancy should be changed to alternative antihypertensive treatments which have an established safety profile for use in pregnancy. When pregnancy is diagnosed, treatment with ACE inhibitors should be stopped immediately, and, if appropriate, alternative therapy should be started.



Exposure to ACE inhibitor/ Angiotensin II Receptor Antagonist (AIIRA) therapy exposure during the second and third trimesters is known to induce human foetotoxicity (decreased renal function, oligohydramnios, skull ossification retardation) and neonatal toxicity (renal failure, hypotension, hyperkalaemia) (See section 5.3). Should exposure to ACE inhibitors have occurred from the second trimester of pregnancy, ultrasound check of renal function and skull is recommended. Infants whose mothers have taken ACE inhibitors should be closely observed for hypotension, oliguria and hyperkalaemia (see sections 4.3 and 4.4).



Lactation:



Because insufficient information is available regarding the use of ramipril during breastfeeding (see section 5.2), ramipril is not recommended and alternative treatments with better established safety profiles during breast- feeding are preferable, especially while nursing a newborn or preterm infant.



4.7 Effects On Ability To Drive And Use Machines



Some adverse effects (e.g. symptoms of a reduction in blood pressure such as dizziness) may impair the patient's ability to concentrate and react and, therefore, constitute a risk in situations where these abilities are of particular importance (e.g. operating a vehicle or machinery).



This occurs especially at the start of treatment, when changing over from other preparations and during concomitant use of alcohol. After the first dose or subsequent increases in dose it is not advisable to drive or operate machinery for several hours.



4.8 Undesirable Effects



The safety profile of ramipril includes persistent dry cough and reactions due to hypotension. Serious adverse reactions include angioedema, hyperkalaemia, renal or hepatic impairment, pancreatitis, severe skin reactions and neutropenia/agranulocytosis.



Adverse reactions frequency is defined using the following convention:

4.9 Overdose



Symptoms associated with overdosage of ACE inhibitors may include excessive peripheral vasodilatation (with marked hypotension, shock), bradycardia, electrolyte disturbances, and renal failure. The patient should be closely monitored and the treatment should be symptomatic and supportive. Suggested measures include primary detoxification (gastric lavage, administration of adsorbents) and measures to restore haemodynamic stability, including, administration of alpha 1 adrenergic agonists or angiotensin II (angiotensinamide) administration. Ramiprilat, the active metabolite of ramipril is poorly removed from the general circulation by haemodialysis.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: ACE Inhibitors, plain,



ATC-code: C09A A05



Mechanism of action



Ramipril is a prodrug which, after absorption from the gastrointestinal tract, is hydrolysed in the liver to form the active angiotensin converting enzyme (ACE) inhibitor, ramiprilat which is a potent and long acting ACE inhibitor. Administration of ramipril causes an increase in plasma renin activity and a decrease in plasma concentrations of angiotensin II and aldosterone. The beneficial haemodynamic effects resulting from ACE inhibition are a consequence of the reduction in angiotensin II causing dilatation of peripheral vessels and reduction in vascular resistance. There is evidence suggesting that tissue ACE particularly in the vasculature, rather than circulating ACE, is the primary factor determining the haemodynamic effects.



Angiotensin converting enzyme is identical with kininase II, one of the enzymes responsible for the degradation of bradykinin. There is evidence that ACE inhibition by ramiprilat appears to have some effects on the kallikrein- kinin-prostaglandin systems. It is assumed that effects on these systems contribute to the hypotensive and metabolic activity of ramipril.



Since angiotensin II also stimulates the release of aldosterone, ramiprilat causes a reduction in aldosterone secretion. The average response to ACE inhibitor monotherapy was lower in black (Afro-Caribbean) hypertensive patients (usually a low-renin hypertensive population) than in non-black patients.



Pharmacodynamic effects



Antihypertensive properties:



Administration of ramipril causes a marked reduction in peripheral arterial resistance. Generally, there are no major changes in renal plasma flow and glomerular filtration rate. Administration of ramipril to hypertensive patients results in reduction of both supine and standing blood pressure without a compensatory rise in heart rate.



The antihypertensive effect is evident within one to two hours after the drug intake; peak effect occurs 3 - 6 hours after drug intake and has been shown to be maintained for at least 24 hours after usual therapeutic doses.



The maximum antihypertensive effect of continued treatment with ramipril is generally apparent after 3 to 4 weeks. It has been shown that the antihypertensive effect is sustained under long term therapy lasting 2 years.



Abrupt discontinuation of ramipril does not produce a rapid and excessive rebound increase in blood pressure.



Heart failure:



In addition to conventional therapy with diuretics and optional cardiac glycosides, ramipril has been shown to be effective in patients with functional classes II-IV of the New-York Heart Association. The drug had beneficial effects on cardiac haemodynamics (decreased left and right ventricular filling pressures, reduced total peripheral vascular resistance, increased cardiac output and improved cardiac index). It also reduced neuroendocrine activation.



Clinical efficacy and safety



Cardiovascular prevention/Nephroprotection;



A preventive placebo-controlled study (the HOPE-study), was carried out in which ramipril was added to standard therapy in more than 9,200 patients.



Patients with increased risk of cardiovascular disease following either atherothrombotic cardiovascular disease (history of coronary heart disease, stroke or peripheral vascular disease) or diabetes mellitus with at least one additional risk factor (documented microalbuminuria, hypertension, elevated total cholesterol level, low high-density lipoprotein cholesterol level or cigarette smoking) were included in the study.



The study showed that ramipril statistically significantly decreases the incidence of myocardial infarction, death from cardiovascular causes and stroke, alone and combined (primary combined events).

The MICRO-HOPE study, a predefined substudy from HOPE, investigated the effect of the addition of ramipril 10 mg to the current medical regimen versus placebo in 3,577 patients at least



The primary analysis showed that 117 (6.5 %) participants on ramipril and 149 (8.4 %) on placebo developed overt nephropathy, which corresponds to a RRR 24 %; 95 % CI [3-40], p = 0.027.



The REIN study, a multicenter randomized, double-blind parallel group, placebo-controlled study aimed at assessing the effect of treatment with ramipril on the rate of decline of glomerular function rate (GFR) in 352 normotensive or hypertensive patients (18-70 years old) suffering from mild (i.e. mean urinary protein excretion > 1 and < 3 g/24 h) or severe proteinuria (



The main analysis of patients with the most severe proteinuria (stratum prematurely disrupted due to benefit in ramipril group) showed that the mean rate of GFR decline per month was lower with ramipril than with placebo; - 0.54 (0.66) vs. -0.88 (1.03) ml/min/month, p = 0.038. The intergroup difference was thus 0.34 [0.03-0.65] per month, and around 4 ml/min/year; 23.1 % of the patients in the ramipril group reached the combined secondary endpoint of doubling of baseline serum creatinine concentration and/or end- stage renal disease (ESRD) (need for dialysis or renal transplantation) vs. 45.5 % in the placebo group (p = 0.02).

For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Modified-release tablet containing enteric-coated (gastro-resistant) naproxen and film-coated esomeprazole.



Oval, biconvex, yellow tablet marked '500/20' in black ink.



4. Clinical Particulars



4.1 Therapeutic Indications



Symptomatic treatment of osteoarthritis, rheumatoid arthritis and ankylosing spondylitis, in patients who are at risk for developing non-steroidal anti-inflammatory drug (NSAID)-associated gastric and/or duodenal ulcers and where treatment with lower doses of naproxen or of other NSAIDs is not considered sufficient.



4.2 Posology And Method Of Administration



Posology in adults



The dose is 1 tablet (500 mg/20 mg) twice daily.



Undesirable effects of naproxen may be minimised by using the lowest effective dose for the shortest duration possible (see section 4.4). In patients not treated with a NSAID previously, a lower daily dose of naproxen or of another NSAID should be considered. When total daily dose of 1000 mg of naproxen is not considered appropriate, alternative therapeutic regimens should be utilized.



Treatment should be continued to achieve individual treatment goals, reviewed at regular intervals and discontinued if no benefit seen.



Due to the delayed release of naproxen from the enteric-coated formulation, VIMOVO is not intended for the treatment of acute pain conditions (such as dental pain or gout). However, flares of osteoarthritis, rheumatoid arthritis and ankylosing spondylitis may be treated with VIMOVO.



Method of administration



VIMOVO must be swallowed whole with water, and not split, chewed or crushed.



It is recommended that VIMOVO is taken at least 30 minutes prior to food intake (see section 5.2).



Special populations



Patients with renal impairment



In patients with mild to moderate renal impairment VIMOVO should be used cautiously and renal function should be monitored closely. A reduction in the total daily naproxen dose should be considered (see sections 4.4 and 4.5). When total daily dose of 1000 mg of naproxen is considered not appropriate, alternative therapeutic regimens should be utilized.



VIMOVO is contraindicated in patients with severe renal impairment (creatinine clearance <30 ml/minute) because accumulation of naproxen metabolites has been seen in patients with severe renal failure and in those on dialysis (see sections 4.3 and 4.4).



Patients with hepatic impairment



In patients with mild to moderate hepatic impairment VIMOVO should be used cautiously and hepatic function should be monitored closely. A reduction in the total daily naproxen dose should be considered (see sections 4.4 and 5.2). When total daily dose of 1000 mg of naproxen is considered not appropriate, alternative therapeutic regimens should be utilized.



VIMOVO is contraindicated in patients with severe hepatic impairment (see sections 4.3 and 5.2).



Elderly (>65 years)



The elderly are at an increased risk of the serious consequences of adverse reactions (see sections 4.4 and 5.2). When total daily dose of 1000 mg of naproxen is considered not appropriate (e.g. in elderly with impaired renal function or low body weight), alternative therapeutic regimens should be utilized.



Children (



VIMOVO is not recommended for use in children, due to lack of data on safety and efficacy.



4.3 Contraindications



• Known hypersensitivity to naproxen, esomeprazole, substituted benzimidazoles, or to any of the excipients



• History of asthma, urticaria or allergic-type reactions induced by administration of aspirin or other NSAIDs (see section 4.4)



• Third trimester of pregnancy (see section 4.6)



• Severe hepatic impairment (e.g. Childs-Pugh C)



• Severe heart failure



• Severe renal impairment



• Active peptic ulceration (see section 4.4, gastrointestinal effects Naproxen)



• Gastrointestinal bleeding, cerebrovascular bleeding or other bleeding disorders (see section 4.4, Haematological effects)



• VIMOVO must not be used concomitantly with atazanavir and nelfinavir (see sections 4.4 and 4.5).



4.4 Special Warnings And Precautions For Use



General



The use of VIMOVO with other concomitant NSAIDs including cyclooxygenase-2 selective inhibitors should be avoided. VIMOVO can be used with low dose aspirin. (See also section 4.5.)



Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms (see section 4.2, and GI and cardiovascular risks below).



When total daily dose of 1000 mg of naproxen is considered not appropriate, alternative therapeutic regimens should be utilized.



Risk-factors to develop NSAID related gastro-intestinal complications include high age, concomitant use of anticoagulants, corticosteroids, other NSAIDs including low-dose acetylsalicylic acid, debilitating cardiovascular disease, and a history of gastric and/or duodenal ulcers.



In patients with the following conditions, naproxen should only be used after a rigorous benefit-risk ratio:



• Inducible porphyries



• Systemic lupus erythematosis and mixed connective tissue disease. There may be an increased risk of aseptic meningitis in these patients.



Patients on long-term treatment (particularly those treated for more than a year) should be kept under regular surveillance.



VIMOVO contains very low levels of methyl- and propyl parahydroxybenzoate, which may cause allergic reactions (possibly delayed). (See sections 2 and 6.1).



Elderly



Naproxen: The elderly have an increased frequency of adverse reactions especially gastro-intestinal bleeding, and perforation, which may be fatal (see sections 4.2 and 5.2). The esomeprazole component of VIMOVO decreased the incidence of ulcers in elderly.



Gastrointestinal effects:



Naproxen: GI bleeding, ulceration or perforation, which can be fatal, has been reported with all NSAIDs at anytime during treatment, with or without warning symptoms or a previous history of serious GI events.



The risk of GI bleeding, ulceration or perforation with NSAIDs is higher with increasing NSAID doses, in patients with a history of ulcer, particularly if complicated with haemorrhage or perforation (see section 4.3), and in the elderly. These patients should begin treatment on the lowest dose available. Combination therapy with protective agents (e.g. misoprostol or proton pump inhibitors) should be considered for these patients, and also for patients requiring concomitant low dose aspirin, or other drugs likely to increase gastrointestinal risk (see below and 4.5). The esomeprazole component of VIMOVO is a proton pump inhibitor.



Patients with a history of GI toxicity, particularly when elderly, should report any unusual abdominal symptoms (especially GI bleeding) particularly in the initial stages of treatment.



Caution should be advised in patients receiving NSAIDs with concomitant medications which could increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective serotonin-reuptake inhibitors or anti-platelet agents such as aspirin (for information on use of VIMOVO with low-dose aspirin, see section 4.5).



Ulcer complications such as bleeding, perforation and obstruction were not studied in the VIMOVO trials.



When GI bleeding or ulceration occurs in patients receiving VIMOVO, the treatment should be withdrawn (see section 4.3).



NSAIDs should be given with care to patients with a history of gastrointestinal disease (ulcerative colitis, Crohn's disease) as these conditions may be exacerbated (see section 4.8 Undesirable effects).



Esomeprazole: In the presence of any alarm symptom (e.g. significant unintentional weight loss, recurrent vomiting, dysphagia, haematemesis or melaena) and when gastric ulcer is suspected or present, malignancy should be excluded, as treatment with esomeprazole magnesium may alleviate symptoms and delay diagnosis.



Dyspesia could still occur despite the addition of esomperazole to the combination tablet (see section 5.1).



Treatment with proton pump inhibitors may lead to slightly increased risk of gastrointestinal infections such as Salmonella and Campylobacter (see section 5.1).



Esomeprazole, as all acid-blocking medicines, might reduce the absorption of vitamin B12 (cyanocobalamin) due to hypo- or achlorhydria. This should be considered in patients with reduced body stores or risk factors of reduced vitamin B12 absorption on long-term therapy.



Cardiovascular and cerebrovascular effects



Naproxen: Appropriate monitoring and advice are required for patients with a history of hypertension and/or mild to moderate congestive heart failure as fluid retention and oedema have been reported in association with NSAID therapy.



Clinical trial and epidemiological data suggest that use of coxibs and some NSAIDs (particularly at high doses and in long-term treatment) may be associated with a small increased risk of arterial thrombotic events (e.g. myocardial infarction or stroke). Although data suggest that the use of naproxen (1000 mg daily) may be associated with a lower risk, some risk cannot be excluded.



Patients with uncontrolled hypertension, congestive heart failure, established ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease should only be treated with naproxen after careful consideration. Similar consideration should be made before initiating longer-term treatment of patients with risk factors for cardiovascular events (e.g. hypertension, hyperlipidaemia, diabetes mellitus, smoking).



Renal effects



Naproxen: Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a NSAID may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state (see also below, and sections 4.2 and 4.5).



Use in patients with impaired renal function



As naproxen and its metabolites is eliminated to a large extent (95%) by urinary excretion via glomerular filtration, it should be used with great caution in patients with impaired renal function and the monitoring of serum creatinine and/or creatinine clearance is advised in these patients. VIMOVO is contraindicated in patients having a baseline creatinine clearance of less than 30 ml/minute (see section 4.3).



Haemodialysis does not decrease the plasma concentration of naproxen because of the high degree of protein binding.



Certain patients, specifically those whose renal blood flow is compromised, because of extracellular volume depletion, cirrhosis of the liver, sodium restriction, congestive heart failure, and pre-existing renal disease, should have renal function assessed before and during VIMOVO therapy. Some elderly patients in whom impaired renal function may be expected, as well as patients using diuretics, may also fall within this category. A reduction in daily dosage should be considered to avoid the possibility of excessive accumulation of naproxen metabolites in these patients.



Hepatic effects



Borderline elevations of one or more liver tests may occur in patients taking NSAIDs. Hepatic abnormalities may be the result of hypersensitivity rather than direct toxicity. Rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported.



Hepatorenal syndrome



The use of NSAIDs may be associated with acute renal failure in patients with severe hepato-cirrhosis. These patients frequently also have concomitant coagulopathy related to inadequate synthesis of clotting factors. Antiplatelet effects associated with naproxen could further increase risk of severe bleeding in these patients.



Haematological effects



Naproxen: Patients who have coagulation disorders or are receiving drug therapy that interferes with haemostasis should be carefully observed if naproxen-containing products are administered.



Patients at high risk of bleeding and those on full anti-coagulation therapy (e.g. dicoumarol derivates) may be at increased risk of bleeding if given naproxen-containing products concurrently (see section 4.5).



Naproxen decreases platelet aggregation and prolongs bleeding time. This effect should be kept in mind when bleeding times are determined.



When active and clinically significant bleeding from any source occurs in patients receiving VIMOVO, the treatment should be withdrawn.



Eye effects



Naproxen: Because of adverse eye findings in animal studies with NSAIDs, it is recommended that an ophthalmic examination be carried out if any change or disturbance in vision occurs.



Dermatological effects



Naproxen: Serious skin reactions, some of them fatal, including exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis, have been reported very rarely in association with the use of NSAIDs (see section 4.8). Patients appear to be at highest risk of these reactions early in the course of therapy, the onset of the reaction occurring within the first month of treatment in the majority of cases. VIMOVO should be discontinued at the first appearance of skin rash, mucosal lesions, or any other sign of hypersensitivity.



Anaphylactic (anaphylactoid) reactions



Naproxen: Hypersensitivity reactions may occur in susceptible individuals. Anaphylactic (anaphylactoid) reactions may occur both in patients with and without a history of hypersensitivity or exposure to aspirin, other NSAIDs or naproxen-containing products. They may also occur in individuals with a history of angio-oedema, bronchospastic reactivity (e.g. asthma), rhinitis and nasal polyps.



Pre-existing asthma



Naproxen: The use of aspirin in patients with aspirin-sensitive asthma has been associated with severe bronchospasm, which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, VIMOVO should not be administered to patients with this form of aspirin sensitivity (see section 4.3) and should be used with caution in patients with pre-existing asthma.



Inflammation



Naproxen: The anti-pyretic and anti-inflammatory activities of naproxen may reduce fever and other signs of inflammation, thereby diminishing their utility as diagnostic signs.



Female fertility



The use of VIMOVO, as with any drug known to inhibit cyclooxygenase / prostaglandin synthesis, may impair female fertility and is not recommended in women attempting to conceive. In women who have difficulties conceiving or who are undergoing investigation of infertility, withdrawal of VIMOVO should be considered (see section 4.6).



Combination with other medicinal products:



Co-administration of atazanavir with proton pump inhibitors is not recommended (see section 4.5). If the combination of atazanavir with a proton pump inhibitor is judged unavoidable, close clinical monitoring (e.g. virus loading) is recommended in combination with an increase in the dose of atazanavir to 400 mg with 100 mg of ritonavir; esomeprazole 20 mg should not be exceeded and therefore VIMOVO must not be used concomitantly with atazanavir (see section 4.3).



Esomeprazole is a CYP2C19 inhibitor. When starting or ending treatment with esomeprazole, the potential for interactions with drugs metabolised through CYP2C19 should be considered. An interaction is observed between clopidogrel and omeprazole (see section 4.5). The clinical relevance of this interaction is uncertain. As a precaution, concomitant use of esomeprazole and clopidogrel should be discouraged.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Contraindications of concomitant use (see section 4.3)



Antiretroviral agents



Omeprazole, the racemate of D+S omeprazole (esomeprazole), has been reported to interact with some antiretroviral drugs. The clinical importance and the mechanisms behind these interactions are not always known. Increased gastric pH during omeprazole treatment may change the absorption of the antiretroviral drug. Other possible interaction mechanisms are via CYP2C19. For some antiretroviral drugs, such as atazanavir and nelfinavir, decreased serum levels have been reported when given together with omeprazole. Co-administration of omeprazole (40 mg once daily) with atazanavir 300 mg/ritonavir 100 mg to healthy volunteers resulted in a substantial reduction in atazanavir exposure (approximately 75% decrease in AUC, Cmax and Cmin). Increasing the atazanavir dose to 400 mg did not compensate for the impact of omeprazole on atazanavir exposure. Co-administration of omeprazole (40 mg qd) reduced mean nelfinavir AUC, Cmax and Cmin by 36-39% and mean AUC, Cmax and Cmin for the pharmacologically active metabolite M8 was reduced by 75-92%.



For other antiretroviral drugs, such as saquinavir, increased serum levels have been reported. There are also some antiretroviral drugs of which unchanged serum levels have been reported when given with omeprazole.



No interaction study has been performed with VIMOVO and atazanavir. However, due to the similar pharmacodynamic and pharmacokinetic properties of omeprazole and esomeprazole, the concomitant use of atazanavir and nelfinavir with esomeprazole is not recommended and concomitant administration with VIMOVO is contraindicated (see section 4.3).



Concomitant use with precaution



Other analgesics including cyclooxygenase-2 selective inhibitors:



Concomitant use of two or more NSAIDs should be avoided as this may increase the risk of adverse effects, especially gastrointestinal ulcers and bleeding. The concomitant use of VIMOVO with other NSAIDs, except for low-dose aspirin (< 325 mg/day), is not recommended (see section 4.4).



Aspirin



VIMOVO can be administered with low-dose aspirin (



Ciclosporin and tacrolimus



As with other non-steroidal anti-inflammatory drugs, caution is advised when ciclosporin is co-administered because of the increased risk of nephrotoxicity.



There is a possible risk of nephrotoxicity when NSAIDs are given with tacrolimus.



Diuretics



Clinical studies, as well as postmarketing observations, have shown that NSAIDs can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy (see section 4.4).



Selective Serotonin Reuptake Inhibitors (SSRIs)



Concomitant use of NSAIDs, including COX-2 selective inhibitors, and SSRIs increases the risk of gastrointestinal bleeding (see section 4.4).



Corticosteroids



There is an increased risk of gastrointestinal bleeding when corticosteroids are combined with NSAIDs including COX-2 selective inhibitors. Caution should be used when NSAIDs are administered concomitantly with corticosteroids (see section 4.4).



ACE-inhibitors



Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors, and may increase the risk of renal impairment associated with the use of ACE-inhibitors. Therefore, the combination should be given with caution in patients with impaired renal function, especially elderly patients.



Digoxin



NSAIDs may increase plasma cardiac glycoside levels when co-administered with cardiac glycosides such as digoxin.



Lithium



NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity.



Methotrexate



Caution is advised where methotrexate is administered concurrently because of possible enhancement of its toxicity, since naproxen, in common with other non-steroidal anti-inflammatory drugs, has been reported to reduce the tubular secretion of methotrexate in an animal model.



Sulphonylureas, Hydantoins



Naproxen is highly bound to plasma albumin; it thus has a theoretical potential for interaction with other albumin-bound drugs such as sulphonylureas, and hydantoins. Patients simultaneously receiving naproxen and a hydantoin, sulphonamide or sulphonylurea should be observed for adjustment of dose if required.



Clopidogrel



In a crossover clinical study, clopidogrel (300-mg loading dose followed by 75 mg/day) alone and with omeprazole (80 mg at the same time as clopidogrel) were administered for 5 days. The exposure to the active metabolite of clopidogrel was decreased by 46% (Day 1) and 42% (Day 5) when clopidogrel and omeprazole were administered together. Mean inhibition of platelet aggregation (IPA) was diminished by 47% (24 hours) and 30% (Day 5) when clopidogrel and omeprazole were administered together. In another study it was shown that administering clopidogrel and omeprazole at different times did not prevent their interaction that is likely to be driven by the inhibitory effect of omeprazole on CYP2C19. Esomeprazole is expected to give a similar interaction with clopidogrel.



Inconsistent data on the clinical implications of this PK/PD interaction in terms of major cardiovascular events have been reported from both observational and clinical studies.



Anti-coagulants and thrombocyte aggregation inhibitors



NSAIDs may enhance the effects of oral anti-coagulants (e.g. warfarin, dicoumarol) heparins and thrombocyte aggregation inhibitors (see section 4.4).



Concomitant administration of 40 mg esomeprazole to warfarin-treated patients showed that, despite a slight elevation in the trough plasma concentration of the less potent R isomer of warfarin, the coagulation times were within the accepted range. However, from post marketed use cases of elevated INR of clinical significance have been reported during concomitant treatment with warfarin. Close monitoring is recommended when initiating and ending treatment with warfarin or other coumarine derivatives.



Beta receptor-blockers



Naproxen and other NSAIDs can reduce the antihypertensive effect of propranolol and other beta-blockers.



Probenecid



Probenecid given concurrently increases naproxen anion plasma levels and extends its plasma half-life significantly.



Drugs with gastric pH-dependent absorption



The gastric acid suppression during treatment with esomeprazole and other PPIs might decrease or increase the absorption of drugs with a gastric pH dependent absorption. Like with other drugs that decrease the intragastric acidity, the absorption of drugs such as ketoconazole, itraconazole, posaconazole and erlotinib can decrease while the absorption of drugs such as digoxin can increase during treatment with esomeprazole. Concomitant use with posaconazole and erlotinib should be avoided. Concomitant treatment with omeprazole (20 mg daily) and digoxin in healthy subjects increased the bioavailability of digoxin by 10% (up to 30% in two out of ten subjects).



Other Information Concerning Drug Interactions



Studies evaluating concomitant administration of esomeprazole and either naproxen (non-selective NSAID) or rofecoxib (COX-2-selective NSAID) did not identify any clinically relevant interaction.



As with other NSAIDs, concomitant administration of cholestyramine can delay the absorption of naproxen.



In healthy volunteers, concomitant administration of 40 mg esomeprazole resulted in a 32% increase in area under the plasma concentration-time curve (AUC) and a 31% prolongation of elimination half-life (t1/2) but no significant increase in peak plasma levels of cisapride. The slightly prolonged QTc interval observed after administration of cisapride alone, was not further prolonged when cisapride was given in combination with esomeprazole (see also section 4.4).



Esomeprazole has been shown to have no clinically relevant effects on the pharmacokinetics of amoxicillin and quinidine.



Esomeprazole inhibits CYP2C19, the major esomeprazole metabolising enzyme. Esomeprazole is also metabolised by CYP3A4. The following have been observed in relation to these enzymes:



• Concomitant administration of 30 mg esomeprazole resulted in a 45% decrease in clearance of the CYP2C19 substrate diazepam. This interaction is unlikely to be of clinical relevance.



• Concomitant administration of 40 mg esomeprazole resulted in a 13% increase in trough plasma levels of phenytoin in epileptic patients.



• Concomitant administration of esomeprazole and a combined inhibitor of CYP2C19 and CYP3A4, such as voriconazole, may result in more than doubling of the esomeprazole exposure.



• Concomitant administration of esomeprazole and a CYP3A4 inhibitor, clarithromycin (500 mg twice daily), resulted in a doubling of the exposure (AUC) to esomeprazole.



Dose adjustment of esomprazole is not required in any of these cases.



Drugs known to induce CYP2C19 or CYP3A4 or both (such as rifampicin and St. John's Wort) may lead to decreased esomeprazole serum levels by increasing the esomeprazole metabolism.



Omeprazole as well as esomeprazole act as inhibitors of CYP2C19. Omeprazole, given in doses of 40 mg to healthy subjects in a cross-over study, increased Cmax and AUC for cilostazol by 18% and 26% respectively, and one of its active metabolites by 29% and 69% respectively.



Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone antibiotics. Patients taking quinolones may have an increased risk of developing convulsions.



Drug/Laboratory Test Interaction



Naproxen may decrease platelet aggregation and prolong bleeding time. This effect should be kept in mind when bleeding times are determined.



The administration of naproxen may result in increased urinary values for 17-ketogenic steroids because of an interaction between the drug and/or its metabolites with m-di-nitrobenzene used in this assay. Although 17-hydroxy-corticosteroid measurements (Porter-Silber test) do not appear to be artifactually altered, it is suggested that therapy with naproxen be temporarily discontinued 72 hours before adrenal function tests are performed if the Porter-Silber test is to be used.



Naproxen may interfere with some urinary assays of 5-hydroxy indoleacetic acid (5HIAA).



4.6 Pregnancy And Lactation



Pregnancy



Naproxen:



Inhibition of prostaglandin synthesis may adversely affect the pregnancy and/or the embryo/foetal development. Data from epidemiological studies suggest an increased risk of miscarriage and of cardiac malformation and gastroschisis after use of a prostaglandin synthesis inhibitor in early pregnancy. The absolute risk for cardiovascular malformation was increased from less than 1%, up to approximately 1.5%. The risk is believed to increase with dose and duration of therapy. In animals, administration of a prostaglandin synthesis inhibitor has been shown to result in increased pre- and post-implantation loss and embryo-foetal lethality. In addition, increased incidences of various malformations, including cardiovascular, have been reported in animals given a prostaglandin synthesis inhibitor during the organogenetic period.



Esomeprazole:



There are limited amount of data from the use of esomeprazole in pregnant women. With the racemic mixture omeprazole data on a larger number of exposed pregnancies stemming from epidemiological studies indicate no malformative nor foetotoxic effects. Animal studies with esomeprazole do not indicate direct or indirect harmful effects with respect to embryonal/fetal development. Animal studies with the racemic mixture do not indicate direct or indirect harmful effects with respect to pregnancy, parturition or postnatal development.



During the first and second trimester of pregnancy, VIMOVO should not be given unless clearly necessary. If VIMOVO is used by a woman attempting to conceive, or during the first and second trimester of pregnancy, the duration of treatment should be kept as short as possible.



During the third trimester of pregnancy, all prostaglandin synthesis inhibitors may expose the foetus to:



• cardiopulmonary toxicity (with premature closure of the ductus arteriosus and pulmonary hypertension);



• renal dysfunction, which may progress to renal failure with oligo-hydroamniosis;



the mother and the neonate, at the end of pregnancy, to:



• possible prolongation of bleeding time, an anti-aggregating effect which may occur even at very low doses.



• inhibition of uterine contractions resulting in delayed or prolonged labour.



Consequently, VIMOVO is contraindicated during the third trimester of pregnancy.



Fertility



The use of NSAIDs like naproxen may impair female fertility. The use of VIMOVO is not recommended in women attempting to conceive (see section 4.4).



Breastfeeding



Naproxen is excreted in low quantities in human milk. It is unknown whether esomeprazole is excreted in human milk. A published case report on the racemic mixture omeprazole indicated excretion of low quantities in the human breast milk (weight adjusted dose < 7%). VIMOVO should not be used during breastfeeding.



4.7 Effects On Ability To Drive And Use Machines



When driving vehicles or operating machines it should be taken into account that some of the adverse effects (e.g. dizziness) reported following the use of VIMOVO may reduce the ability to react.



4.8 Undesirable Effects



Summary of safety profile



Immediate release esomeprazole has been included in the tablet formulation to decrease the incidence of gastrointestinal side effects from naproxen. VIMOVO has been shown to significantly decrease the occurrence of gastric ulcers and NSAID associated upper gastrointestinal adverse events compared to naproxen alone (see section 5.1).



No new safety findings were identified during VIMOVO treatment in the overall study population (n=1157) compared to the well-established safety profiles of the individual active substances naproxen and esomeprazole.



Tabulated summary of adverse reactions



Adverse reactions are classified according to frequency and System Organ Class. Frequency categories are defined according to the following convention: Very common (>1/10), Common (>1/100 to <1/10), Uncommon (>1/1,000 to <1/100), Rare (>1/10,000 to <1/1,000), Very rare (<1/10,000), Not known (cannot be estimated from the available data)
