Potassium-sparing agents during diuretic therapy in hypertension.

Three pharmacological agents in use as "potassium-sparing" drugs have been tested by serial measurements of total exchangeable potassium (K(E)) during 4 to 12 weeks of oral diuretic therapy in hypertensive subjects. Triamterene seemed ineffective in the dosage used (50 mg twice daily). Spironolactone (25 mg twice daily) reduced K loss to a considerable extent, while Slow-K (32 mEq daily) completely reversed previous K(E) deficits. Plasma K levels were a poor indication of degree of K(E) restoration.

Body composition changes in hypertensive subjects on long-term oral diuretic therapy.

Hypertensive patients were treated with either chlorthalidone or frusemide for periods of two to four months. Reduction in blood pressure was seen with chlorthalidone but not with frusemide. This hypotensive effect appeared to be independent of the natriuretic effect.A significant reduction in total exchangeable potassium (K(E)) was seen with both agents, but no patient showed adverse symptoms or signs. There was no alteration in maximal urinary concentration or acidification, or in intravenous glucose tolerance or plasma insulin. It is concluded that potassium depletion of this degree does not require replacement therapy on a routine basis in hypertensive patients.
