Managing high blood pressure often involves choosing the right medication, and two commonly prescribed options are Losartan and Lisinopril.
While both are effective in lowering blood pressure and protecting heart health, they work in slightly different ways and come with distinct side effects.
In this losartan vs lisinopril comparison, we’ll break down everything you need to know so you can better understand which option may suit your needs.
What Is Losartan?
Losartan belongs to a class of drugs called Angiotensin II Receptor Blockers (ARBs).
- Works by blocking angiotensin II, a chemical that narrows blood vessels
- Helps blood vessels relax and widen
- Commonly prescribed for high blood pressure and kidney protection
What Is Lisinopril?
Lisinopril is part of the ACE inhibitor class.
- Blocks the enzyme that produces angiotensin II
- Reduces blood vessel constriction
- Often used for hypertension, heart failure, and after heart attacks
