BETOPTIC vs HEMANGEOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces intraocular pressure by decreasing aqueous humor production.
Hemangeol (propranolol hydrochloride) is a non-selective beta-adrenergic receptor antagonist that competitively blocks beta-1 and beta-2 receptors. In infantile hemangioma, the exact mechanism is not fully understood, but proposed actions include vasoconstriction, inhibition of angiogenesis by downregulating VEGF and bFGF, and induction of apoptosis in endothelial cells.
Instill 1 drop of 0.5% solution in the affected eye(s) twice daily.
3 mg/kg/day orally divided into 2 doses for pediatric patients; adult use not indicated

Terminal elimination half-life: 4–5 hours. With topical ophthalmic administration, systemic absorption is minimal, so half-life refers to IV data.
3-4 hours in infants (0-1 year) and 3.5-4.5 hours in children (1-6 years); clinical context: requires TID dosing to maintain therapeutic effect.
Renal (fecal <5%). 60% as unchanged drug, 40% as inactive metabolites.
Primarily hepatic metabolism via UGT1A9 and CYP2C9; <5% excreted unchanged in urine. Biliary/fecal elimination of metabolites; exact % not defined.
