Mechanism of action

Amiloride acts as an epithelial sodium channel (ENaC) inhibitor in the distal tubule and collecting duct of the kidney. By blocking sodium reabsorption, it promotes natriuresis and diuresis while preventing potassium loss, making it useful in conditions requiring fluid removal without hypokalemia. It is often used in combination with loop or thiazide diuretics to counteract their potassium-wasting effects.
