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.
CARTROL is a beta-1 selective adrenergic receptor antagonist. It inhibits the effects of catecholamines on beta-1 receptors in the heart, reducing heart rate, myocardial contractility, and blood pressure.
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.
Adults: 2.5 mg orally twice daily, titrated up to maximum 10 mg twice daily.

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 is 6–8 hours in normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <30 mL/min).
Primarily metabolized by red blood cell esterases; <1% excreted unchanged in urine. Elimination is not dependent on renal or hepatic function.
Primarily renal excretion (approx. 70% unchanged drug), with 20% biliary/fecal, and 10% metabolism to inactive metabolites.
