Which medication is commonly used to treat hypertension?

Lisinopril is commonly used to treat hypertension because it belongs to a class of medications known as ACE inhibitors (Angiotensin-Converting Enzyme inhibitors). These drugs work by relaxing blood vessels, which helps lower blood pressure and improve blood flow. They also have additional benefits such as protecting kidney function and reducing the risk of heart failure, making them a popular choice for managing hypertension in a variety of patient populations.

Atenolol is also used to treat hypertension, but it is a beta-blocker, which primarily reduces heart rate and the output of blood by the heart. While effective, it is often considered secondary to ACE inhibitors as first-line therapy.

Gabapentin is primarily used for nerve pain and seizures, and diphenhydramine is an antihistamine used mainly for allergies and insomnia, neither of which are indicated for treating hypertension. Understanding the specific indications and mechanisms of action for these medications is crucial in selecting the appropriate treatment for hypertension.
