Two medicines, side by side
Atenolol vs metoprolol
Atenolol and metoprolol are both labeled for high blood pressure, angina and heart attack and coronary artery disease. Drugs@FDA records approvals of atenolol since 1981 and of metoprolol since 1978. Pharmacies paid $0.0217 per atenolol 25 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).
Check it at the source: the atenolol FDA label on DailyMed (effective September 18, 2025); the metoprolol FDA label on DailyMed (effective March 3, 2026).
