Captopril is an anti-hypertensive medication used for:

• Lowering the blood pressure
• Treating heart failure
• Reduce the risk of heart failure and improve survival after a heart attack among patients with left ventricular hypertrophy
• Treating kidney disease among patients with diabetes type 1 and retinopathy, a type of eye disease
• Treating kidney disease in people with type 1 diabetes

This medication is an ACE inhibitor or angiotensin-converting enzymes. ACE inhibitors are mostly prescribed for the treatment and management of high blood pressure or hypertension and congestive heart failure.  ACE inhibitors cause the blood vessels to relax as well as to decrease the blood volume. A decrease in the volume of blood may lead to a decrease in the level of blood pressure and also a decrease in oxygen demand by the heart.

Captopril blocks the action of the ACE converting enzyme known as angiotensin II. It is a potent enzyme that causes the smooth muscles in the blood vessels to become narrow and constrict. The narrowing of the blood vessels increases the pressure in the vessel which causes high blood pressure.

High blood pressure or hypertension is a common condition but when left untreated it can cause damages to the heart, brain, blood vessels, kidney and other organs of the body. Damage to these organs may cause stroke, heart attack, heart and kidney failure, and other serious health problems.

Captopril, as an ACE inhibitor, can slow down the activity of angiotensin II. As a result, it relaxes and dilates the blood vessels which helps lower the blood pressure and improve the condition of the heart. Lowering the blood pressure allows the heart to pump blood around the body with ease. Captopril can improve the overall function of the heart and slows down the progression of the disease in the blood vessels within the kidney.
