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.
Non-selective beta-adrenergic receptor antagonist (beta-blocker) with intrinsic sympathomimetic activity (ISA) and weak local anesthetic (membrane-stabilizing) activity. Reduces intraocular pressure by decreasing aqueous humor production.
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.
Ophthalmic: Instill 1 drop of 1% or 2% solution into affected eye(s) twice daily. Oral: 2.5 mg to 5 mg once daily; may increase to 10 mg once daily if needed. Maximum dose 10 mg 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 5-6 hours in patients with normal renal function; may extend to 24-36 hours in severe renal impairment.
Primarily metabolized by red blood cell esterases; <1% excreted unchanged in urine. Elimination is not dependent on renal or hepatic function.
Renal excretion of unchanged drug and active metabolite (8-hydroxycarteolol) accounts for 50-70% of elimination. Biliary/fecal excretion is minimal (<10%).
