Résumé : | A multicenter, randomized, double-blind, crossover, placebo-controlled study was conducted in 90 isosorbide dinitrate responders showing stable angina to compare the efficacy of molsidomine retard, 8 mg b.i.d. with that of molsidomine, 4 mg t.i.d., for 6 weeks. Total work performance (workload x min) was significantly improved, compared with baseline and placebo until 8 and 12 h after molsidomine and molsidomine retard administration, respectively. ST-segment depression decreased significantly under the two treatments at 60 W as well as at maximal exercise. The rate-pressure product (heart rate x systolic blood pressure) decreased and increased significantly at submaximal and maximal exercise level, respectively. All these effects remained significant after 6-week treatment, with only the ST segment showing a nonsignificant tendency to improvement at maximal work. The frequency of anginal attacks and of sublingual nitroderivative-tablets consumption decreased significantly with molsidomine, 4 mg, and molsidomine retard, 8 mg. However, overall results showed that the latter form reduces myocardial ischemia more efficiently at submaximal exercise level, has a more prolonged effect on exercise tolerance, and maintains it at a somewhat higher level after 6-week treatment. |
