[Hypotensive effect and characteristics of the effect on the central hemodynamics of the delayed-action form of diltiazem (Dilren) in patients with hypertension].

Calcium antagonist dilren in a short course was given to 11 hypertensive subjects (AH stage II). A clinical response in the majority of the patients was associated with a decline in systolic, mean arterial and resting diastolic pressure (by 8.1, 7.8 and 11.5%, respectively). In orthostasis and under isometric loading dynamic values of arterial pressure tended to lowering, especially diastolic (by 6.7 and 8.3%, respectively). Reduced pressure resulted from a significant reduction in the total peripheral resistance (by 19.8% at rest, in orthostasis by 10%, in isometric load by 26.1%). Minute blood volume increased because of a rise in stroke output. Dilren is recommended in a standard dose 300 mg/day in mild hypertension and in an individual dose 600 mg/day in moderate disease.
