Losartan vs. Diovan: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 28, 2023
Losartan and Diovan are both angiotensin II receptor blockers (ARBs) used to treat high blood pressure; however, they are different medications.
Key Differences
Both are medications primarily prescribed for the treatment of hypertension (high blood pressure). These drugs belong to the class of medications known as angiotensin II receptor blockers (ARBs).
While both effectively lower blood pressure, their chemical structures and formulations are different. This means that even if they achieve similar results, the compounds themselves are not identical.
Both drugs can be used for conditions other than hypertension. For example, losartan can be prescribed for stroke prevention, while Diovan might be used to treat heart failure.
Potential side effects may vary between the two. While some patients may tolerate one better than the other, it's essential to monitor any adverse reactions closely under a physician's guidance.
Both medications can interact with other drugs. Therefore, it's crucial for patients to inform their doctors of all medications they are taking, ensuring no harmful drug interactions occur.
