Which class of medication does Lisinopril belong to?

Lisinopril belongs to the class of medications known as ACE inhibitors, which stands for Angiotensin-Converting Enzyme inhibitors. This type of medication is typically used to treat conditions such as hypertension (high blood pressure) and heart failure. ACE inhibitors work by relaxing blood vessels, which helps to lower blood pressure and reduce the workload on the heart. By inhibiting the enzyme that converts angiotensin I to angiotensin II, they decrease the amount of angiotensin II in the body. Angiotensin II is a compound that causes blood vessels to constrict, so reducing its levels leads to improved blood flow and lower blood pressure.

The other classes of medications mentioned in the options serve different purposes. Beta blockers are primarily used for lowering heart rate and blood pressure, diuretics help to eliminate excess fluid by increasing urine output, and anti-inflammatory drugs reduce inflammation and pain. However, they do not function in the same manner as ACE inhibitors, which specifically target the renin-angiotensin system to manage cardiovascular conditions.
