Generic Name: Lisinopril dihydrate
Product Name: Chem mart Lisinopril


Lisinopril is a drug used in the treatment of mild to moderate hypertension; congestive heart failure; and in patients who have suffered from a heart attack.


Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor which blocks the production of a hormone (chemical signal carried in the blood) called angiotensin II. Angiotensin II is a chemical that is made by the body, which narrows blood vessels and thereby maintains (and elevates) blood pressure. ACE is important for the formation of angiotensin II. When ACE is blocked by lisinopril, angiotensin cannot be converted into its active form, angiotensin II, and blood pressure falls (due to relaxation and widening of the arteries). Lowering the blood pressure puts less strain on the heart and therefore lisinopril improves the pumping efficiency of the heart and is used to treat patients with heart failure. In some patients who have had a heart attack, lisinopril helps the heart to recover and helps to prevent later complications such as heart failure or weakness of the heart muscle.
