How Enalapril for pets works
[[EDITOR|DRUG_DISPLAY_NME|||title]] is an angiotensin-converting enzyme (ACE) inhibitor. It relaxes blood vessels by blocking the enzyme that causes them to tighten. This widens the blood vessels, which lowers blood pressure and makes it easier for the heart to pump blood throughout your pet’s body.
Enalapril also relaxes blood vessels in the kidneys, which can help treat certain kidney conditions.

Risks and warnings for Enalapril for pets
Enalapril can cause some serious health issues. This risk might be even higher for certain pets. If this worries you, talk to your veterinarian about other options.
Low blood pressure
- Risk factors: Aortic stenosis | Obstructive hypertrophic cardiomyopathy | Taking other blood pressure medications
Enalapril can lower your pet’s blood pressure. But if their dose is too high, it could make their blood pressure too low . This can be especially dangerous if your pet has certain heart conditions, like aortic stenosis and hypertrophic cardiomyopathy. Also, taking enalapril with other blood pressure-lowering medications can also cause your pet’s blood pressure to drop too low. Tell your vet if your pet has any of these heart conditions before starting enalapril or other blood pressure-lowering medications.
Low kidney filtration
- Risk factors: Heart failure | Dehydration
Enalapril can reduce how well your pet’s kidneys filter waste. If your pet already has poor kidney function caused by conditions like heart failure or dehydration, this medication could make it even worse. Your vet will help decide if enalapril is safe for your pet.
