Mechanism of action:

Antihypertensive Exact mechanism of antihypertensive action is unknown but is thought to be related to competitive inhibition of angiotensin I – converting enzyme (ACE) activity, resulting in a decreased rate of conversion of angiotensin I to angiotensin II, which is a potent vasoconstrictor. Decreased angiotensin II concentrations results in a secondary increase in plasma renin activity (PRA)

vasodilator, congestive heart failure: Decrease in peripheral vascular resistance,pulmonary capillary wedge pressure and pulmonary vascular resistance;and improved cardiac output and exercise tolerance.
