1 The effect of pindolol administered to twenty‐six patients with hypertension of unknown origin was compared with respect to blood pressure and plasma renin activity change after increase of the dose over a period of 6 weeks. 2 There was no clear correlation between the fall of plasma renin activity, which in some patients was very marked, and the fall in blood pressure. Some patients with a fall in plasma renin activity did not drop their pressure. Conversely, some with a fall of pressure did not drop their plasma renin activity. 3 The addition of hydrochlorothiazide to the pindolol finally caused further lowering of the blood pressure in all but one patient and the plasma renin activity rose in all but two patinets. There was no clear correlation between change in plasma renin activity and the effect on blood pressure.
