title: Antihypertensive effect of diacetolol in essential hypertension.
abstract: 1 Diacetolol is the N-acetylated metabolite of acebutolol and possesses beta-adrenergic receptor blocking properties. 2 Its antihypertensive action was assessed in accordance with a double-blind randomised cross-over scheme in 17 patients with moderate essential hypertension previously well controlled with acebutolol. 3 Significant reductions in lying mean arterial blood pressure were observed with daily doses of 200 mg (- 9%), 400 mg (- 10%) and 800 mg (- 14%), and were associated with significant decreases in heart rate and plasma renin activity. 4 The diacetolol mean plasma level measured 8 to 10 h after drug ingestion was proportional to the dose (207 +/- 27, 394 +/- 63 and 823 +/- 135 ng/ml for respectively 200, 400 and 800 mg/day).
