BETAXOLOL HYDROCHLORIDE vs INDERAL LA
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.
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.
10-20 mg orally once daily; maximum 20 mg/day.
Initial: 80 mg orally once daily; titrate to 120-160 mg once daily; maximum 640 mg/day.

Terminal elimination half-life: 14–22 hours (mean 16 hours); sufficient for once-daily dosing in hypertension; prolonged in 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: 80% (as unchanged drug and inactive metabolites), Fecal: 20%
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.
