Enalapril 20 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Enalapril 20 mg?

Enalapril 20 mg is a prescription medicine used to treat high blood pressure (hypertension), heart failure, and certain other heart-related conditions. It belongs to a group of medicines called angiotensin-converting enzyme (ACE) inhibitors.

Enalapril works by relaxing blood vessels, allowing blood to flow more easily. This lowers blood pressure, reduces the workload on the heart, and helps improve circulation.

Controlling high blood pressure can lower the risk of serious complications such as heart attack, stroke, kidney damage, and heart failure.

How Enalapril Works

The body produces a substance called angiotensin II, which narrows blood vessels and increases blood pressure.

Enalapril works by:

• Blocking the angiotensin-converting enzyme (ACE).
• Reducing the production of angiotensin II.
• Relaxing and widening blood vessels.
• Lowering blood pressure.
• Reducing strain on the heart.
• Helping protect kidney function in some patients.
