Normally, sodium is reabsorbed in the collecting tubules of a renal nephron. This occurs via epithelial sodium channels or ENaCs, located on the luminal surface of principal cells that line the collecting tubules. Positively-charged Na+ entering the cells during reabsorption leads to an electronegative luminal environment causing the secretion of potassium (K+) into the lumen/ urine in exchange. Sodium reabsorption also causes water retention. Web20 Mar 2024 · As their names suggest, potassium-sparing diuretics work by increasing urine volume without decreasing potassium. Potassium-sparing diuretics include spironolactone and amiloride. Spironolactone prevents the action of aldosterone, a steroid hormone produced by the adrenal gland.
