This comprehensive guide aims to provide a clear and concise overview of lisinopril 20 mg, covering key aspects relevant to its safe and effective use.
Lisinopril 20 mg
Lisinopril 20 mg is a medication used to treat high blood pressure (hypertension) and heart failure. It belongs to a class of drugs known as angiotensin-converting enzyme (ACE) inhibitors. Lisinopril works by blocking the production of angiotensin II, a hormone that constricts blood vessels, leading to an increase in blood pressure. By inhibiting this process, lisinopril helps to relax blood vessels, lower blood pressure, and reduce the workload on the heart.
Chemical Structure and Properties
Lisinopril is a synthetic peptide-like compound with the chemical formula C21H31N3O5. It is a white to off-white crystalline powder that is practically insoluble in water.
The chemical structure of lisinopril consists of a central proline ring attached to a side chain containing a carboxyl group, a sulfhydryl group, and a terminal amino group. This structure is essential for its activity as an ACE inhibitor.
History of Development and Approval
Lisinopril was first synthesized in the 1970s by researchers at Merck & Co. It was initially studied for its potential use in treating hypertension and other cardiovascular conditions. After extensive clinical trials, lisinopril was approved by the Food and Drug Administration (FDA) in 1987 for the treatment of hypertension.
Since then, lisinopril has become a widely used and effective medication for managing hypertension and heart failure. It is available in various formulations, including tablets, capsules, and oral solutions.
