[Moducrin--a new combined preparation in the treatment of hypertension (author's transl)]

A product combining 25 mg hydrochlorothiazide, 2.5 mg amiloride hydrochloride and 10.0 mg timolol maleate (Moducrin) was tested in 20 previously untreated hypertensive persons. The systolic blood pressure before treatment was 199.1 +/- 24.8 mmg Hg and after treatment 149.1 +/- 19.1 mm Hg. Diastolic blood pressure showed a drop from 120.9 +/- 11.9 mm Hg to 92.2 +/- 13.3 mm Hg. Both decreases were highly significant (p less than 0.01). The heart rate, moreover, was reduced during treatment from 81.5 +/- 11.1 beats per minute to 66.8 +/- 9.25 beats (p less than 0.01). Haemoglobin, haematocrit and serum uric acid showed significant changes, but did not reach pathological ranges. Treatment had to be stopped in only one case in this study because of incipient asthmatic bronchitis. We conclude that this combination drug has a very good antihypertensive effect and is well tolerated.
