title: [Time-dependent effects of antihypertensive agents and chronocorrecting action of melatonin in patients with arterial hypertension].
abstract: The chronopharmacodynamics of angiotension-converting enzyme (ACE) inhibitors, such as ramipril (R), enalapril (E), acetene (A), caposide-50 (C-50) and the effect of the epiphyseal neurohormone melatonin used alone and in combination with cozaar (Co) and cintome (Ci) in the randomized groups including 124 patients with arterial hypertension (AH). The ACE inhibitors were given in the morning, afternoon, and evening. Co and Ci were used in the morning. Melatonin was given at 10.00 p.m. 10-14 days before and after therapy, 24-hour monitoring (Astracard, Russia) and echocardiography (Toshiba, Japan) were performed. Analyzing the findings indicated the time-dependent hemodynamic effects of R, E, and C-50. Ci, A, and Co were found to have antihypertensive and vasodilatory effects without normalizing the chronostructure of circadian rhythms of major hemodynamic parameters. By producing antihypertensive and vasodilatory effects, melatonin leads to the recovery of circadian hemodynamic organization when used alone and in combination with Co, Ci, and ACE inhibitors.
