Amiloride is a medication primarily used as a diuretic, which helps the body eliminate excess fluid. It works by blocking sodium channels in the kidneys, leading to increased sodium excretion while retaining potassium. This makes it useful in treating conditions like high blood pressure and heart failure. In addition to its diuretic properties, Amiloride is sometimes used to manage certain types of kidney disorders. It is often prescribed in combination with other diuretics to enhance their effectiveness while minimizing potassium loss, which can be a side effect of many other diuretics.
