Moexipril tablets are a medication belonging to the class of drugs known as ACE inhibitors (Angiotensin-Converting Enzyme inhibitors). They are primarily used to treat hypertension (high blood pressure) and heart failure. Moexipril works by inhibiting the action of ACE, an enzyme responsible for producing a substance called angiotensin II. Angiotensin II normally causes blood vessels to narrow, leading to increased blood pressure. By blocking ACE, moexipril helps to relax blood vessels, lower blood pressure, and improve blood flow throughout the body. This can reduce the workload on the heart and decrease the risk of heart-related complications.
