Dosage of Isdn AL retard in details

Isdn AL retard Dosage

Generic name: Isdn AL retard 40mg

Dosage form: tablet, extended release

The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.

As noted under “CLINICAL PHARMACOLOGY”, multiple-dose studies with Isdn AL retard and other nitrates have shown that maintenance of continuous 24-hour plasma levels results in refractory tolerance. Every dosing regimen for Isdn AL retard ER tablets must provide a daily dose-free interval to minimize the development of this tolerance. With immediate-release Isdn AL retard, it appears that one daily dose-free interval must be at least 14 hours long. The necessary dose-free interval for Isdn AL retard ER tablets has not been clearly identified, but is presumably somewhat longer.

As also noted under “CLINICAL PHARMACOLOGY”, only one trial has ever studied the use of controlled-release Isdn AL retard for more than one dose. In that trial, 40 mg of a different formulation of controlled-release Isdn AL retard was administered twice daily in doses given 6 hours apart. After 4 weeks, active treatment could not be distinguished from placebo.

Large controlled studies with other nitrates suggest that no dosing regimen with Isdn AL retard ER tablets should be expected to provide more than about 12 hours of continuous anti-anginal efficacy per day.

In clinical trials, immediate-release oral Isdn AL retard has been administered in a variety of regimens, with total daily doses ranging from 30 mg to 480 mg.

Isdn AL retard interactions

Blood Pressure Lowering Agents: The concomitant use of drugs with blood pressure lowering properties, e.g. vasodilators, beta-blockers, calcium channel antagonists, ACE inhibitors, neuroleptics or tricyclic antidepressants and alcohol may potentiate the antihypertensive effect of Isdn AL retard.

Phosphodiesterase Inhibitors: A blood pressure lowering effect of Isdn AL retard will be increased, if used together with phosphodiesterase inhibitors (e.g. sildenafil, tadalafil, vardenafil). This might lead to life-threatening cardiovascular complications. Patients who are on Isdn AL retard therapy therefore must not use phosphodiesterase inhibitors (e.g. sildenafil, tadalafil, vardenafil).

Patients who have recently taken phosphodiesterase inhibitors (e.g. sildenafil, vardenafil, tadalafil) therefore must not receive acute Isdn AL retard therapy.

Dihydroergotamine: Isdn AL retard used in combination with dihydroergotamine may lead to higher blood concentration of dihydroergotamine and thus increase the effect of this medicinal product.

Sapropterine: Sapropterine contains the API Tetrahydrobiopterine (BH4). BH4 is a cofactor for nitric oxide synthetase. Caution is recommended during concomitant use of sapropterine-containing medicine with all agents that cause vasodilation by affecting nitric oxide (NO) metabolism or action, including classical NO donors [e.g. glyceryl trinitrate (GTN), Isdn AL retard (ISDN), isosorbide mononitrate and others].
