[Clinical trial of a combination preparation of clonidine and cyclothiazide (author's transl)].

Three dosage combinations of clonidine and cyclothiazide were tested in at least 20 patients each, under clinical (4 weeks) and oupatients (longterm) conditions, in order to find a suitable combination with fewer side effects than the single drugs with at least equal efficacy for the longterm treatment of hypertension. The combination of 150 mcg clonidine and 2.5 mg cyclothiazide (Dimapres) in the form of a scored oblong sugar-coated tablet seems to satisfy these demands best and to be an optimal combination of clonidine and cyclothiazide. It is an antihypertensive agent which has shown particularly good results in mild and moderate hypertension, as demonstrated by daily measurement of blood pressure and ergometric tests.
