Two medicines, side by side
Bisoprolol vs losartan
Bisoprolol and losartan are both labeled for high blood pressure. Drugs@FDA records approvals of bisoprolol since 1992 and of losartan since 1995. Pharmacies paid $0.114 per bisoprolol fumarate 5 mg tablet and $0.0327 per losartan potassium 50 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, bisoprolol is a beta-adrenergic blocker and losartan an angiotensin 2 receptor blocker.
Check it at the source: the bisoprolol FDA label on DailyMed (effective March 11, 2026); the losartan FDA label on DailyMed (effective January 20, 2026).
