Two medicines, side by side
Acebutolol vs metoprolol
Acebutolol and metoprolol are both labeled for high blood pressure. Drugs@FDA records approvals of acebutolol since 1984 and of metoprolol since 1978. Pharmacies paid $0.615 per acebutolol 200 mg capsule 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).
