Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonselective beta-adrenergic receptor antagonist; competitively blocks beta1- and beta2-adrenergic receptors, leading to decreased heart rate, myocardial contractility, and blood pressure. Also prolongs sinoatrial node refractory period and inhibits renin release.
Selective beta-1 adrenergic receptor antagonist with nitric oxide-mediated vasodilatory activity via stimulation of beta-3 receptors.
40 mg orally once daily for hypertension; initial dose 40 mg once daily for angina, titrate up to 80-240 mg once daily. Maximum dose 320 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: 20-24 hours (may extend to 40 hours in renal impairment). Clinical context: Allows once-daily dosing; steady-state achieved in 5-7 days.
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.
Renal (unchanged, ~85-90%); fecal (<5%); biliary (<2%).
Approximately 38% renal, 48% fecal (unchanged drug and metabolites); extensive hepatic metabolism (CYP2D6) with glucuronidation; <1% excreted unchanged in urine.
