Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive beta-blocker with alpha1-blocking activity; decreases cardiac output, reduces peripheral vascular resistance.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, myocardial contractility, and blood pressure by blocking catecholamine effects at beta-1 receptors. Also suppresses renin release.
6.25 mg orally twice daily, titrated up to a maximum of 25 mg twice daily for heart failure; 12.5 mg orally once daily for hypertension, titrated to 25-50 mg daily.
25 to 100 mg orally once daily, titrated at weekly intervals as tolerated; maximum 400 mg/day

7-10 hours (terminal elimination half-life); clinical context: supports twice-daily dosing for sustained beta-blockade.
Terminal elimination half-life: 3-7 hours. Twice-daily dosing (metoprolol succinate) provides stable beta-blockade over 24 hours due to extended-release formulation, not due to half-life.
Primarily hepatic metabolism (CYP2D6 and CYP2C9) followed by biliary excretion into feces; ~60% fecal elimination as metabolites, ~16% renal elimination of unchanged drug plus metabolites.
Primarily renal (95% as metabolites, <5% unchanged). Three main metabolites: O-demethylated (active), α-hydroxylated (active), and O-demethylated and α-hydroxylated. Biliary/fecal excretion: <5%.
