The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.
Metoprololsuccinat Stada 95 mg is an extended-release tablet intended for once daily administration. For treatment of hypertension and angina, when switching from immediate-release Metoprololsuccinat Stada 95 mg to Metoprololsuccinat Stada 95 mg, use the same total daily dose of Metoprololsuccinat Stada 95 mg. Individualize the dosage of Metoprololsuccinat Stada 95 mg. Titration may be needed in some patients.
Metoprololsuccinat Stada 95 mg tablets are scored and can be divided; however, do not crush or chew the whole or half tablet.
Hypertension
Adults: The usual initial dosage is 25 to 100 mg daily in a single dose. The dosage may be increased at weekly (or longer) intervals until optimum blood pressure reduction is achieved. In general, the maximum effect of any given dosage level will be apparent after 1 week of therapy. Dosages above 400 mg per day have not been studied.
Pediatric Hypertensive Patients ≥ 6 Years of age: A pediatric clinical hypertension study in patients 6 to 16 years of age did not meet its primary endpoint (dose response for reduction in SBP); however, some other endpoints demonstrated effectiveness. If selected for treatment, the recommended starting dose of Metoprololsuccinat Stada 95 mg is 1 mg/kg once daily, but the maximum initial dose should not exceed 50 mg once daily. Dosage should be adjusted according to blood pressure response. Doses above 2 mg/kg (or in excess of 200 mg) once daily have not been studied in pediatric patients.
Metoprololsuccinat Stada 95 mg is not recommended in pediatric patients < 6 years of age.
Angina Pectoris
Individualize the dosage of Metoprololsuccinat Stada 95 mg. The usual initial dosage is 100 mg daily, given in a single dose. Gradually increase the dosage at weekly intervals until optimum clinical response has been obtained or there is a pronounced slowing of the heart rate. Dosages above 400 mg per day have not been studied. If treatment is to be discontinued, reduce the dosage gradually over a period of 1 - 2 weeks.
Heart Failure
Dosage must be individualized and closely monitored during up-titration. Prior to initiation of Metoprololsuccinat Stada 95 mg, stabilize the dose of other heart failure drug therapy. The recommended starting dose of Metoprololsuccinat Stada 95 mg is 25 mg once daily for two weeks in patients with NYHA Class II heart failure and 12.5 mg once daily in patients with more severe heart failure. Double the dose every two weeks to the highest dosage level tolerated by the patient or up to 200 mg of Metoprololsuccinat Stada 95 mg. Initial difficulty with titration should not preclude later attempts to introduce Metoprololsuccinat Stada 95 mg. If patients experience symptomatic bradycardia, reduce the dose of Metoprololsuccinat Stada 95 mg. If transient worsening of heart failure occurs, consider treating with increased doses of diuretics, lowering the dose of Metoprololsuccinat Stada 95 mg or temporarily discontinuing it. The dose of Metoprololsuccinat Stada 95 mg should not be increased until symptoms of worsening heart failure have been stabilized.

Metoprololsuccinat Stada 95 mg interactions
Metoprololsuccinat Stada 95 mg is a CYP2D6 substrate. Drugs that inhibit CYP2D6 can have an effect on the plasma concentration of Metoprololsuccinat Stada 95 mg. Examples of drugs that inhibit CYP2D6 are quinidine, terbinafine, paroxetine, fluoxetine, sertraline, celecoxib, propafenon and diphenhydramine. When treatment with these drugs are initiated, the dose of Metoprololsuccinat Stada 95 mg might have to be reduced for patients treated with Metoprololsuccinat Stada 95 mg.
The Following Combinations with Metoprololsuccinat Stada 95 mg Should be Avoided: Barbituric Acid Derivatives: Barbiturates (investigated for pentobarbital) induce the metabolism of Metoprololsuccinat Stada 95 mg by enzyme induction.
Propafenone: Upon administration of propafenone to 4 patients on Metoprololsuccinat Stada 95 mg therapy, the plasma concentrations of Metoprololsuccinat Stada 95 mg increased by 2-5 fold and 2 patients experienced side effects typical of Metoprololsuccinat Stada 95 mg. The interaction was confirmed in 8 healthy volunteers. The interaction is probably explained by the fact that propafenone, similarly to quinidine, inhibits the metabolism of Metoprololsuccinat Stada 95 mg via cytochrome P450 2D6. The combination is probably difficult to handle since propafenone also has beta-receptor blocking properties.
Verapamil: In combination with beta-receptor blocking drugs (described for atenolol, propranolol and pindolol), verapamil may cause bradycardia and fall in blood pressure.
Verapamil and beta-blockers have additive inhibitory effects on AV-conduction and sinusnode function.
The Following Combinations with Metoprololsuccinat Stada 95 mg may require Modified Drug Dosage:
Antiarrhythmics, Class I: Class I antiarrhythmics and beta-receptor blocking drugs have additive negative inotropic effects which may result in serious haemodynamic side effects in patients with impaired left ventricular function. The combination should also be avoided in "sick sinus syndrome" and pathological AV-conduction. The interaction is best documented for disopyramide.
Nonsteroidal Anti-Inflammatory/Antirheumatic Drugs (NSAIDs): NSAID-antiphlogistics have been shown to counteract the antihypertensive effect of beta-receptor blocking drugs. Primarily, indomethacin has been studied. This interaction probably does not occur with sulindac. A negative interaction study on diclofenac has been performed.
Diphenhydramine: Diphenhydramine decreases (2.5 times) clearance of Metoprololsuccinat Stada 95 mg to alpha-hydroximetoprolol via CYP2D6 in fast hydroxylating persons. The effects of Metoprololsuccinat Stada 95 mg are enhanced. Diphenhydramine may probably inhibit the metabolism of other CYP2D6 substrates.
Digitalis Glycosides: Digitalis glycosides in association with beta-blockers, may increase AV conduction time and may induce bradycardia.
Diltiazem: Diltiazem and beta-receptor blockers have additive inhibitory effects on the AV-conduction and sinusnode function. Pronounced bradycardia has been observed (case reports) during combination treatment with diltiazem.
Epinephrine: There are about 10 reports on patients treated with nonselective beta-receptor blockers (including pindolol and propranolol) that developed pronounced hypertension and bradycardia after administration of epinephrine (adrenaline). These clinical observations have been confirmed in studies in healthy volunteers. It has also been suggested that epinephrine in local anaesthetics may provoke these reactions upon intravasal administration. The risk is probably less with cardioselective beta-receptor blockers.
Phenylpropanolamine: Phenylpropanolamine (norephedrine) in single doses of 50 mg may increase the diastolic blood pressure to pathological values in healthy volunteers. Propranolol generally counteracts the rise in blood pressure induced by phenylpropanolamine. However, beta-receptor blockers may provoke paradoxical hypertensive reactions in patients who take high doses of phenylpropranolamine. Hypertensive crisis during treatment with only phenylpropanolamine have been described in a couple of cases.
Quinidine: Quinidine inhibits the metabolism of Metoprololsuccinat Stada 95 mg in so-called rapid hydroxylators (>90% in Sweden) with markedly elevated plasma levels and enhanced beta-blockade as a result. A corresponding interaction might occur with other beta-blockers metabolised by the same enzyme (cytochrome P450 2D6).
Clonidine: The hypertensive reaction when clonidine is suddenly withdrawn may be potentiated by beta-blockers. If concomitant treatment with clonidine is to be discontinued, the beta-blocker medication should be withdrawn several days before clonidine.
Rifampicin: Rifampicin may induce the metabolism of Metoprololsuccinat Stada 95 mg resulting in decreased plasma levels.
Patients receiving concomitant treatment with other beta-blockers (ie, eye drops) or MAO Inhibitors should be kept under close surveillance. In patients receiving beta-receptor blocker therapy, inhalation anaesthetics enhance the cardio-depressant effect. The dosages of oral antidiabetics may have to be readjusted in patients receiving beta-blockers. The plasma concentration of Metoprololsuccinat Stada 95 mg can increase when cimetidine or hydralazine are administered simultaneously.
