[Treatment of essential arterial hypertension with a single daily dose of acebutolol].

25 patients with essential arterial hypertension were treated with single daily doses of 400 g acebutolol administered for EIGHT weeks in outpatients' departments. The drug proved to be extremely effective in reducing PAS and PAD values in both lying and standing positions. No undesirable side effects were observed except in one case where cardiac insufficiency was controlled by digitalis. It can therefore be concluded that acebutolol is a beta-adrenolytic drug which is reliably effective in the treatment of essential arterial hypertension, well tolerated and easily administered.
