Enalapril requires a prescription from your veterinarian, and is sold per tablet/capsule.

What is Enalapril?
Enalapril is used to treat mild, moderate, or severe heart failure and high blood pressure, and is usually used in combination with other medications.
For: Cats and Dogs

Benefits:
•     Helps the heart beat more efficiently
•     Prevents fluid build-up in the lungs
•     Lowers blood pressure
•     Improves ability to tolerate exercise

How it works:
Enalapril is an angiotensin-converting enzyme (ACE) inhibitor. It works by blocking an enzyme in the body that is needed to produce a substance that causes blood vessels to tighten. As a result, the blood vessels relax. This lowers blood pressure and increases the supply of blood and oxygen to the heart.

Cautions:
Do not give your pet potassium supplements unless directed to by your veterinarian. Enalapril may cause birth defects. Do not give to pregnant animals.
