Drug Class and Mechanism

Avalide is a combination angiotensin II receptor blocker and diuretic. The angiotensin II receptor blocker works by relaxing the blood vessels. Exactly how the diuretic works to decrease blood pressure is unknown, but it helps the kidneys to eliminate fluid and sodium from the body.
