Two medicines, side by side

Olmesartan vs metoprolol

Olmesartan and metoprolol are both labeled for high blood pressure. Drugs@FDA records approvals of olmesartan since 2002 and of metoprolol since 1978. Pharmacies paid $0.0805 per olmesartan medoxomil 20 mg tablet and $0.085 per metoprolol succ ER 100 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. Metoprolol's other strengths are brand-only: $1.20 per mL (Lopressor 10 mg/mL oral solution). In FDA's classes, olmesartan is an angiotensin 2 receptor blocker and metoprolol a beta-adrenergic blocker.

Check it at the source: the olmesartan FDA label on DailyMed (effective September 23, 2025); the metoprolol FDA label on DailyMed (effective March 3, 2026).

Half-life, in each label's words: Olmesartan, “Olmesartan appears to be eliminated in a biphasic manner with a terminal elimination half-life of approximately 13 …”; Metoprolol, “Elimination Elimination is mainly by biotransformation in the liver, and the plasma half-life ranges from approximately …”
