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 no intrinsic sympathomimetic activity or membrane stabilizing activity. Reduces heart rate, myocardial contractility, and blood pressure by blocking catecholamine effects at beta-1 receptors predominantly in cardiac tissue.
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.
Loading dose: 500 mcg/kg IV over 1 minute, followed by maintenance infusion of 50 mcg/kg/min IV for 4 minutes. Titrate by 50 mcg/kg/min increments every 4 minutes as needed to maximum of 200 mcg/kg/min. For double-strength (20 mg/mL) formulation, adjust infusion rate accordingly.

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 is approximately 9 minutes. Clinical context: ultra-short acting beta-blocker, steady state achieved within 30 minutes.
Renal (unchanged, ~85-90%); fecal (<5%); biliary (<2%).
Rapid metabolism by red blood cell esterases; metabolites are inactive. Less than 2% excreted unchanged in urine.
