[Results of the treatment of essential arterial hypertension following prolonged (24 months administration of acebutolol)].

Acebutolol, a new cardioselective blocking agent, has been used to treat essential hypertension during two years in 56 patients. The initial dosage was 600 mg a day and was sufficient in the majority of patients. We have observed a perfect control of arterial blood pressure in 69 p.cent. In 10 p.cent of our patients arterial blood pressure decreased and the mean decrease was 25 mm Hg. In 21 p.cent there was no effect of the treatment. Tolerance was very good.
