Vasotec: Enalapril for Dogs

If you’ve got a dog with heart problems then you’ve probably already heard about Enalapril for dogs. Well, Enalapril for dogs is actually a drug that is classed as an angiotensin-converting enzyme inhibitor. In other words, it’s main job is to lower blood pressure by relaxing the tone of the blood vessel.

Enalapril often goes under the name Vasotec. This FDA approved drug is used to mainly treat cases of hypertension (aka high blood pressure) in dogs. Hypertension can be quite a severe problem in our pets. If left untreated, hypertension can lead to:

  • a disruption in the circulatory system
  • damage to the vessels of the circulatory system
  • damage to the heart
  • exercise intolerance
  • kidney problems
  • heart attack
  • stroke

Often dogs with hypertension may experience symptoms like:

  • seizures
  • circling
  • eye and nose bleeds
  • vision loss

How Does it Work?

If you’re a veterinary student or a science lover then you’re in for a treat. Because the mechanism of action for this drug is just a little science lesson waiting to be learned.

Enalapril for dogs is a drug that belongs to a class of other drugs called your angiotensin-converting enzyme inhibitors. For short, we will call these guys your ACE. Now, the ACE is an enzyme that is produced naturally by the kidneys. In the body, this enzymes the main function to control blood pressure by causing the blood vessels to constrict.

ACE inhibitors, on the other hand, do the opposite! Rather than constricting blood vessels, the ACE inhibitors relax blood vessels. This relaxing of the blood vessels ultimately leads to decreases blood flow, and therefore decreasing blood pressure.

Therefore enalapril for dogs works by actually blocking the angiotensin-converting enzyme. And, as a result, we see not only a decrease in blood pressure but also an increase in the blood’s oxygen carrying capacity.

Treating Dog Heart Problems: 4 Uses of Enalapril Maleate for Dogs

As a general rule of thumb, enalapril for dogs may be used as part of the treatment for any disease that causes hypertension (elevated blood pressure). Since there may be many causes of hypertension in dogs, we will cover just the top 5 causes of hypertension common to our canine companions.

  1. Congestive Heart Failure in dogs: Congestive heart failure in dogs is a disease that results in fluid accumulation and pulmonary edema. Enalapril may be used to increase the heart’s ability to pump oxygen-rich blood more effectively.

  3. Cushing’s Disease in dogs 
  4. Hyperthyroidism 

Kidney Problems in Dogs: This Drug will Help Dogs with Kidney Failure!

ACE inhibitors may be frequently used in cases of chronic kidney disease. Many pets diagnosed with kidney disease may succumb to hypertension (elevated blood pressure). As a result of hypertension, it is quite common to find dogs experiencing cases of sudden blindness and retinal detachment.

To prevent the negative effects of hypertension, it is very likely that your veterinarian will prescribe ACE inhibitors such as Enalapril maleate.

So depending on your dog’s individual case, Enalapril can affect the kidneys by:

  • Decreases proteinuria
  • Decreases glomerular basement membrane splitting
  • Delay increases in serum creatinine

Therefore, overall, dogs treated with Enalapril for cases of hypertension relating to kidney disease may have an increased survival rate.
