title: The antihypertensive and biochemical effects of hydrochlorothiazide/amiloride (Moduretic) versus chlorthalidone.
abstract: In an open two-period crossover study hydrochlorothiazide/amiloride and chlorthalidone were compared with regard to their anti-hypertensive and biochemical properties in ambulatory patients with mild to moderate hypertension. Twenty-five out of twenty-six patients completed the study. In the chlorthalidone group plasma potassium was consistently lower than in the hydrochlorothiazide/amiloride group, the difference achieved significance at 8 and 12 weeks after the start of treatment. With regard to the hypertension and other parameters no statistically significant differences were found.
