[Use of isoptin SR-240 in treatment of hypertension].

The effectiveness of hypotensive action and tolerance of Isoptin SR-240 were studied in 20 patients with primary arterial hypertension. The drug was used in doses 240-360 mg daily (mean dose 324 mg daily). Blood pressure returned to normal values in 12 (60%) out of 20 patients. In the remaining eight cases no blood pressure normalization was achieved. Side effects occurred in five patients. General worsening of wellbeing and easy tiring were most frequently observed. The results of the present work indicate that Isoptin SR-240 is an effective hypotensive drug, useful in the treatment of mild and moderate arterial hypertension.
