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 by blocking catecholamine effects at beta-1 receptors.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, myocardial contractility, and blood pressure by blocking catecholamine effects at beta-1 receptors, predominantly in cardiac tissue.
Intravenous: For stable patients, an initial loading dose of 500 mcg/kg/min over 1 minute followed by a maintenance infusion of 50 mcg/kg/min for 4 minutes; if response is inadequate, increase maintenance infusion to 100 mcg/kg/min and repeat loading dose after 10 minutes. Titrate in 50 mcg/kg/min increments up to 200 mcg/kg/min. For intraoperative and postoperative use, see full prescribing information.
50 mg orally twice daily, titrate up to 100 mg twice daily as needed.

Terminal elimination half-life is approximately 9 minutes (range 8–10 minutes). Clinically, the half-life is consistent with rapid offset of effect upon discontinuation; steady state is achieved within 30 minutes of continuous infusion.
Terminal elimination half-life: 3-7 hours (mean 4.5 h); may be prolonged in hepatic impairment or elderly
Primarily metabolized by red blood cell esterases; <1% excreted unchanged in urine. Elimination is not dependent on renal or hepatic function.
Renal: ~95% (primarily as metabolites, <5% unchanged); fecal: ~5%
