Description
Capoten 50mg Tablets contain Captopril, an Angiotensin-Converting Enzyme (ACE) inhibitor used for the treatment of high blood pressure (hypertension), heart failure, and to improve survival after a heart attack. It also protects the kidneys in patients with diabetic nephropathy.
Capoten works by relaxing and widening the blood vessels, allowing blood to flow more easily, which lowers blood pressure and reduces strain on the heart.
