Résumé :

A double-blind, placebo-controlled, crossover study was performed in 50 patients with ischemic heart disease and stable angina to determine the duration of efficacy of 8 mg molsidomine in extended-release form. Exercise testing was performed at baseline and 2, 4, 6, 8, and 10 h after intake of either the medication or the placebo. Total duration of exercise (in minutes) and total work performance (workload x min) was significantly improved in the molsidomine retard group, not only compared with baseline but also with placebo for all timepoints. ST segment depression at 60 W and at maximal exercise improved similarly until 10 h after molsidomine retard treatment. The rate-pressure product (heart rate x systolic blood pressure) showed significant improvement only at 60 W. No attenuation of the obtained effects was observed after 14 days of treatment. The number of anginal attacks and the consumption of sublingual nitroderivates were significantly reduced with molsidomine retard 8 mg as compared with placebo. Molsidomine retard 8 mg is effective until at least 10 h after oral (p.o.) intake. A dose schedule of molsidomine retard 8 mg twice daily definitely reduces anginal symptoms.
