Enalapril vs. Losartan: Comparing ACE Inhibitors and ARBs for Blood Pressure
Enalapril (an ACE inhibitor) and Losartan (an ARB) are both commonly prescribed medications to treat high blood pressure and other heart conditions. While they work in similar pathways to lower blood pressure, they belong to different drug classes and have distinct characteristics that may make one a better choice for certain patients.
Side-by-Side Comparison
| Category | Enalapril Maleate | Losartan Potassium |
|---|---|---|
| Drug Class | ACE Inhibitor (Angiotensin-Converting Enzyme Inhibitor) | ARB (Angiotensin II Receptor Blocker) |
| Primary Use | High blood pressure, heart failure | High blood pressure, heart failure (off-label for some uses), stroke risk reduction |
| Mechanism of Action | Blocks the enzyme that converts angiotensin I to angiotensin II, leading to vasodilation and reduced blood pressure. | Directly blocks angiotensin II from binding to its receptors, preventing its effects like vasoconstriction. |
| Common Side Effect | Dry, persistent cough (due to bradykinin accumulation) | Less likely to cause a cough compared to ACE inhibitors |
| Key Advantage | Well-established efficacy for heart failure and post-heart attack | Often preferred if an ACE inhibitor causes a bothersome cough |
| Main Limitation | Risk of persistent dry cough, angioedema | May be less effective in preventing certain cardiovascular events in some populations compared to ACE inhibitors |
| When to Choose | Your doctor might choose Enalapril if you have high blood pressure or heart failure, especially if you tolerate ACE inhibitors well and have no history of a cough with these medications. It's a very effective and widely used option for many cardiovascular conditions. | Losartan may be preferred if you develop a persistent dry cough while taking Enalapril or another ACE inhibitor, as ARBs generally do not cause this side effect. It's also a good choice for high blood pressure and can be used in patients who cannot tolerate ACE inhibitors. |
| Side Effects | Both medications can cause dizziness, fatigue, and kidney problems, especially in dehydrated patients. However, Enalapril is specifically known for causing a dry, persistent cough in some people, which is much less common with Losartan. Both carry a risk of angioedema (severe swelling), though it is generally lower with Losartan. | |
| Cost | Both Enalapril and Losartan are available as generic medications, making them generally affordable. The exact cost can vary based on your insurance plan and pharmacy. |
Bottom Line
Enalapril and Losartan are both effective for managing high blood pressure and other heart conditions, but they belong to different drug classes. The main difference for patients is the lower likelihood of a dry cough with Losartan. Your doctor will consider your specific health conditions, tolerance to medications, and potential side effects to determine which drug is best for you.
Enalapril Maleate Overview
Enalapril maleate is a medication called an ACE inhibitor, primarily used to treat high blood pressure and heart failure. It works by relaxing blood vessels, which helps lower blood pressure and makes it easier for your heart to pump blood. This can improve symptoms and overall heart function.

Losartan potassium (Cozaar) is an angiotensin II receptor blocker (ARB) used to treat high blood pressure, protect the kidneys in type 2 diabetes, and reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy. Unlike ACE inhibitors, losartan does not cause a dry cough and carries a significantly lower risk of angioedema. It is also the only ARB with a clinically meaningful uricosuric (uric acid-lowering) effect, making it a preferred choice in patients with hypertension and gout.
