Hydralazine Uses

Hydralazine is used to treat high blood pressure (essential hypertension). By controlling blood pressure, this medicine helps to lower the risk of stroke, coronary artery disease, heart attack, heart failure, vision loss, kidney failure, and other serious health problems.

There may be other uses of hydralazine, such as to treat heart failure and after heart valve replacement—your pharmacist or doctor can give you further drug information.

Hydralazine Mechanism of Action

Hydralazine is a vasodilator. It works by relaxing blood vessels and making blood flow easier, thus lowering blood pressure.
