Long term effect of timolol and hydrochlorothiazide, or hydrochlorothiazide and amiloride, in essential hypertension.
Twenty-four patients with mild to moderate hypertension were treated for up to 60 weeks with hydrochlorothiazide and either placebo, timolol, or timolol and amiloride. The effect of adding timolol and amiloride to hydrochlorothiazide was evaluated in a double blind trial. In 22 of the 24 patients a supine diastolic blood pressure below or equal to 95 mm Hg was produced by hydrochlorothiazide and timolol. Replacing a potassium supplement with amiloride increased the antihypertensive effect.
