[Possibilities of potentiating the antianginal action of nitrates by methionine in patients with stable effort angina pectoris].
When given in a single dose, methionine was studied for its effects on the efficacy of isosorbide dinitrate in 8 patients with coronary heart disease. The antianginal and anti-ischemic effects of the agents were evaluated by treadmill exercise testing that had been performed prior to and repeatedly (1, 2, 3, and 6 hours) following a single application of the drug. Methionine in a dose of 1 g failed to produce antianginal and anti-ischemic effects. The concomitant use of isosorbide dinitrate (10 mg) and methionine (1 g) showed significantly pronounced antianginal and anti-ischemic effect than that of isosorbide dinitrate alone. The methionine-induced increase in the effect of isosorbide dinitrate substantially differed in the patients. Thus, methionine is able to potentiate the antianginal and anti-ischemic effect of isosorbide dinitrate.
