Ramipril (Altace) is an angiotensin-converting enzyme (ACE) inhibitor with an IC50 of 5 nM. It is used to treat hypertension and congestive heart failure. ACE inhibitors lower the production of angiotensin II, therefore relaxing arterial muscles while at the same time enlarging the arteries, allowing the heart to pump blood more easily, and increasing blood flow due to more blood being pumped into and through larger passageways.
