Ramipril
Ramipril is an ACE inhibitor used to treat hypertension, heart failure, and to reduce cardiovascular risk after heart attacks. It works by blocking the enzyme that converts angiotensin I to angiotensin II, a substance that narrows blood vessels and raises blood pressure. By inhibiting this process, ramipril relaxes and widens blood vessels, making it easier for the heart to pump blood.
Ramipril is an ACE inhibitor that lowers blood pressure by preventing the formation of angiotensin II, a potent vasoconstrictor.
This medication carries a boxed (black box) warning — the strongest type of FDA warning. Review the full prescribing information before use.

Treatment of hypertension, heart failure, post-myocardial infarction, and diabetic nephropathy. Also used for cardiovascular risk reduction in high-risk patients.
Inhibits angiotensin-converting enzyme (ACE), preventing the conversion of angiotensin I to angiotensin II. This reduces vasoconstriction, decreases aldosterone secretion, and lowers blood pressure.
Contraindicated in pregnancy due to fetal toxicity. Common side effects include dry cough and hyperkalemia. May cause angioedema. Requires monitoring of kidney function and potassium levels. Not for use with aliskiren in diabetic patients.
