BETAGAN vs LABETALOL HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta-1 selective beta-adrenergic receptor antagonist; reduces intraocular pressure by decreasing aqueous humor production.
Labetalol is a non-selective beta-adrenoceptor blocker and selective alpha-1 adrenoceptor blocker. It reduces myocardial contractility, heart rate, and peripheral vascular resistance.
Instill 1 drop of 0.25% or 0.5% solution into the affected eye(s) twice daily.
Oral: Initial 100 mg twice daily, titrate up to 200-400 mg twice daily; maximum 2400 mg/day. IV: 20 mg slow IV over 2 minutes, then 40-80 mg every 10 minutes as needed up to 300 mg total; or continuous IV infusion at 0.5-2 mg/min.

Terminal elimination half-life is approximately 10-15 hours in adults; prolonged in renal impairment (up to 30 hours).
Terminal elimination half-life: 6-8 hours. In renal impairment, half-life may be slightly prolonged but not clinically significant; in hepatic impairment, half-life may be significantly prolonged.
Primarily renal excretion of unchanged drug and metabolites; about 80% eliminated in urine, 20% in feces as unchanged drug or glucuronide conjugates.
Primarily hepatic metabolism; ~5% excreted unchanged in urine; ~55-60% as glucuronide conjugates in urine; fecal excretion <5%.
