ATENOLOL vs HEMANGEOL
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.
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.
50 mg orally once daily; may increase to 100 mg orally once daily if needed.
3 mg/kg/day orally divided into 2 doses for pediatric patients; adult use not indicated

6-9 hours (terminal elimination half-life); may increase to 15-30 hours in renal impairment (CrCl <35 mL/min).
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: 40-50% unchanged drug; minor hepatic metabolism (10-20%) with biliary excretion of metabolites; <5% fecal.
Primarily hepatic metabolism via UGT1A9 and CYP2C9; <5% excreted unchanged in urine. Biliary/fecal elimination of metabolites; exact % not defined.
