FAQ

What class of diuretic is amiloride?

Amiloride is classified as a diuretic that conserves potassium. When combined with another diuretic, such as a thiazide or loop diuretic, amiloride is frequently prescribed.

What is the mechanism of action of amiloride?

Amiloride works by interacting with amiloride-sensitive sodium channels to prevent sodium from being reabsorbed in the kidney’s collecting ducts and distal convoluted tubules. This encourages the body to lose water and salt while leaving potassium untouched.

Is amiloride a vasodilator?

In dogs and rats, 6-iodo-amiloride acts as a vasodilator, vasodepressor, natriuretic, and diuretic. It also causes a prolonged, significant drop in blood pressure in spontaneously hypertensive rats that is unrelated to urinary effects.
