title: Mild hypertension: a clinical trial conducted in hospital general practice.
abstract: To compare findings in a hospital trial of hypotensive drugs with those in a general practice trial several patients with mild hypertension were studied at the same time in hospital and in general practice. They received bendrofluazide and potassium chloride or bendrofluazide, potassium chloride, and reserpine according to a double-blind crossover protocol, and blood biochemical values were studied over eight weeks and six months. When reserpine was withdrawn from nine women they followed a modified protocol comparing bendrofluazide and potassium chloride with potassium chloride alone. The blood pressure values measured by the general practitioners were similar to those measured in hospital. Both the diuretic alone and the diuretic with reserpine produced significant falls in blood pressures. Although plasma renin activity increased on diuretic treatment, continued treatment did not produce a further increase, and levels gradually declined towards normal.
