Patient summary

Designed to relieve hypertension and indicated to support cardiovascular health in patients.

Mechanism of action

This agent inhibits the angiotensin-converting enzyme, which prevents the conversion of angiotensin I to the potent vasoconstrictor angiotensin II. This leads to widened blood vessels, reduced workload on the heart, and lower systemic blood pressure.
