Long-lasting effect of oral molsydomine on exercise performance: a new antianginal agent

This study examines whether the beneficial effects of molsydomine, a
recently introduced antianginal agent, on exercise performance of patients
with angina pectoris are long lasting. The hemodynamic effects are known to
persist for several hours. The effects of molsydomine on the duration of
exercise and the time to the onset of ST depression were compared to those
of placebo during two hours after oral administration. Molsydomine
prolonged the duration of exercise in all eight patients (average 2.8 min,
P less than 0.001) and delayed the onset of ST depression (average 2.2 min,
P less than 0.001), while the placebo failed to alter these measurements.
The increment of the duration of exercise produced by 2 mg of molsydomine
in two hours following oral administration was comparable to the increment
produced in a few minutes after 0.3 mg of nitroglycerin given sublingually.
The results indicate that molsydomine offers prophylasis for angina
pectoris that lasts at least two hours after oral administration.
