Diuretics, beta blockers and vasodilators. Dosage in mild and moderate hypertension.

This paper presents experience with the treatment of mild to moderate hypertension by means of a thiazide diuretic (cyclopenthiazide), a small dose of a beta adrenergic blocking agent (oxprenolol) and progressively increasing doses of a vasodilator (hydrallazine). Satisfactory control of blood pressure was achieved in 38 of 41 cases without the production of distressing effects. This treatment regime was acceptable to patients and appears more promising than other currently available methods for blood pressure control.
