Long-term effects of an amiloride/hydrochlorothiazide combination ('Moduretic') on electrolyte balance

Abstract

A study was carried out of plasma electrolyte estimations made before and after long-term use of a combination of amiloride and hydrochlorothiazide in 23 patients. The mean duration of use was 20.3 months. No significant differences were found in plasma potassium, sodium, bicarbonate or urea from baseline levels.
