title: [Chronopharmacodynamics of delayed-action cardiac glycosides and nitrates].
abstract: In 96 patients with coronary heart disease and stage II circulatory failure, the chronopharmacodynamics of strophanthin, corglycon, and nitrosorbide was studied by using acute clinical and pharmacological tests in the morning (8.00 a.m.), in the afternoon (2.00 p.m.), and in the evening (8.00 p.m.). Central and peripheral hemodynamic parameters were measured prior to and following 5, 15, 30, 60, and 120 min of intravenous injection of cardiac glycosides or sublingual administration of nitrosorbide in a dose of 10 mg for 240 min. The investigations showed that there were the most profound hemodynamic changes in the morning if strophanthin was used and in the afternoon if corglycon was given. The maximal reduction in heart pre- and afterload was seen in the morning when nitrosorbide was applied, the most improvement in central hemodynamic parameters was observed in the evening when nitrosorbide was used.
