Short General Description of the Drug: Lisinopril

Lisinopril is a widely prescribed medication used to treat various cardiovascular conditions. It belongs to the class of drugs known as angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors are commonly used to manage high blood pressure, heart failure, and to improve survival rates after a heart attack. Lisinopril is available in tablet form and is typically taken once daily.

Classification as an Angiotensin-Converting Enzyme (ACE) Inhibitor

The primary mechanism of action of Lisinopril is its inhibition of the angiotensin-converting enzyme (ACE). ACE plays a crucial role in the production of angiotensin II, a hormone that constricts blood vessels and increases blood pressure. By blocking ACE, Lisinopril helps dilate blood vessels and reduce blood pressure, thereby improving blood flow and decreasing the workload on the heart.

Benefits and Uses of Lisinopril:

  • Treatment of hypertension (high blood pressure): Lisinopril is commonly prescribed as a first-line treatment for hypertension. It helps to lower blood pressure and reduce the risk of complications such as heart attacks and stroke.
  • Management of heart failure: Lisinopril can be used alongside other medications in the treatment of heart failure. It helps improve symptoms, increase exercise tolerance, and prolong survival.
  • Post-heart attack recovery: After experiencing a heart attack, patients are often prescribed Lisinopril to reduce the risk of subsequent heart failure and improve chances of survival.
