[A treatment of mild and moderate hypertension with timolol (author's transl)].

21 patients with essential sustained mild or moderate hypertension were treated with timolol for an average of 6 months at a mean dosage of 3,14 tablets per day. The mean decreases of supine systolic and diastolic blood pressures were respectively of 17,8 and 7,3 mm Hg. The efficacy of timolol was considered excellent or good in 11 cases (52,4 p. cent) and its tolerance perfect in 15 cases (71,4 p. cent). The study was extended in 15 cases with one dose of timolol per day. Effectiveness remained excellent in 12 cases. There was neither orthostatic hypotension nor brady-cardia of less than 55 beats per minute nor water retention. Side effects appeared in 6 cases requiring discontinance of therapy in only one case (exertional dyspnea).
