Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Propranolol is a non-selective beta-adrenergic receptor antagonist that competitively blocks beta-1 and beta-2 receptors, decreasing heart rate, myocardial contractility, and blood pressure; also inhibits renin release and reduces sympathetic outflow.
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.
Initial: 80 mg orally once daily; titrate to 120-160 mg once daily; maximum 640 mg/day.

Terminal elimination half-life is 5-6 hours in patients with normal renal function; may extend to 24-36 hours in severe renal impairment.
Terminal elimination half-life is 8-11 hours (range 4-16 hours) after oral administration. The extended-release formulation (INDERAL LA) results in a prolonged half-life of approximately 10 hours, allowing once-daily dosing.
Renal excretion of unchanged drug and active metabolite (8-hydroxycarteolol) accounts for 50-70% of elimination. Biliary/fecal excretion is minimal (<10%).
Primarily hepatic metabolism with renal elimination of metabolites. Less than 1% excreted unchanged in urine. Biliary/fecal excretion of metabolites accounts for approximately 20% of eliminated dose.
