What are the alternatives to losartan?
Losartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs). Other ARBs include valsartan (Diovan), olmesartan (Benicar), and candesartan (Atacand) [4]. Other classes of medications for high blood pressure include ACE inhibitors, calcium channel blockers, diuretics, and beta-blockers [4].
How does losartan work?
Losartan works by blocking the action of angiotensin II, a substance in the body that narrows blood vessels and raises blood pressure. By blocking this substance, losartan helps to relax blood vessels, lower blood pressure, and improve blood flow [1].
What are the common side effects of losartan?
Common side effects of losartan can include dizziness, tiredness, and upset stomach [1]. It is important for patients to discuss any side effects with their healthcare provider.
