Although sustained-release nitrates have been introduced in capsule form in an attempt to achieve prolonged therapeutic action, no objective data are available regarding the efficacy of such preparations in patients with angina pectoris. Therefore, we performed a double-blind investigation to study the effects of therapy with capsules of isosorbide dinitrate upon the exercise tolerance at two and six hours after administration in 28 patients with ischemic heart disease. Maximal graded multistage treadmill exercise was performed before and at two or six hours following the last dose of isosorbide dinitrate administered orally as 40-mg capsules every eight hours for one month. Isosorbide dinitrate administered in this fashion resulted in a significant reduction in anginal episodes, as compared with placebo. As compared to control, ten patients who underwent exercise testing two hours after therapy with isosorbide dinitrate manifested significantly increased duration of exercise (311 to 386 seconds) and maximal oxygen consumption (21.5 to 24.4 ml/kg/min) (both P
