Losartan vs. Lisinopril: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 17, 2023
Losartan is an ARB preventing blood vessel narrowing; lisinopril is an ACE inhibitor reducing blood pressure.

Key Differences

Losartan, a medication categorized as an Angiotensin II Receptor Blocker (ARB), primarily works by blocking the action of Angiotensin II, a natural substance that tightens blood vessels. This relaxation allows for easier blood flow and lower blood pressure. On the other hand, Lisinopril falls under the class of drugs known as ACE (Angiotensin-Converting Enzyme) inhibitors. It works by reducing the production of Angiotensin II, leading to relaxed blood vessels and, consequently, lowered blood pressure.

Losartan is often chosen for its role in protecting the kidney from the effects of diabetes, besides its fundamental function in controlling high blood pressure. Conversely, Lisinopril is frequently prescribed not only for high blood pressure but also for improving survival after a heart attack and for heart failure treatment, demonstrating its cardiovascular benefits.

The side effects of Losartan can include dizziness, upper respiratory infections, and more rarely, muscle cramps or weakness. In contrast, Lisinopril's side effects can be quite distinct, commonly causing a persistent dry cough, dizziness, and, in rare cases, angioedema, a serious swelling of deep skin layers.

In handling special conditions, Losartan is often considered safer for patients with a history of chronic kidney disease and is less likely to cause metabolic issues. Lisinopril, however, while beneficial for heart conditions, may not be suitable for individuals with a history of angioedema or women who are pregnant.

Patients on Losartan must avoid potassium supplements or salt substitutes containing potassium, as the drug can increase potassium levels. Lisinopril users, however, need to be more cautious about the possibility of angioedema and must inform healthcare professionals about any sudden swelling symptoms.
