Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, myocardial contractility, and blood pressure.
Selective beta-1 adrenergic receptor antagonist with nitric oxide-mediated vasodilatory activity via stimulation of beta-3 receptors.
10 mg orally once daily; may increase to 20 mg once daily if needed. Maximum 20 mg/day.
5 mg orally once daily. May be initiated at 2.5 mg in patients with renal impairment or those at risk of hypotension. Titrate at 2-week intervals up to 40 mg once daily.

Terminal elimination half-life is 8-12 hours in healthy adults; may extend to 15-20 hours in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life: 12-19 hours in extensive metabolizers; up to 30-50 hours in poor CYP2D6 metabolizers; clinically, once-daily dosing is effective due to pharmacodynamic half-life >40 hours.
Primarily renal excretion of unchanged drug and metabolites (70-80% unchanged; 20-30% as glucuronide or sulfate conjugates). Biliary/fecal excretion accounts for less than 5%.
Approximately 38% renal, 48% fecal (unchanged drug and metabolites); extensive hepatic metabolism (CYP2D6) with glucuronidation; <1% excreted unchanged in urine.
