BETAGAN vs CARVEDILOL
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.
Carvedilol is a nonselective beta-adrenergic receptor antagonist (beta-1, beta-2) and alpha-1 adrenergic receptor antagonist. It causes vasodilation and reduces heart rate, myocardial contractility, and blood pressure. It also has antioxidant and anti-proliferative effects.
Instill 1 drop of 0.25% or 0.5% solution into the affected eye(s) twice daily.
Heart failure: Initial 3.125 mg orally twice daily, titrate every 2 weeks to 6.25 mg, 12.5 mg, then 25 mg twice daily as tolerated. Target dose: 25 mg twice daily (≤85 kg) or 50 mg twice daily (>85 kg). Hypertension: Initial 6.25 mg orally twice daily, titrate every 1-2 weeks to 12.5 mg, then 25 mg twice daily. Maximum: 50 mg twice daily.

Terminal elimination half-life is approximately 10-15 hours in adults; prolonged in renal impairment (up to 30 hours).
Terminal elimination half-life is 7-10 hours. Steady-state concentrations are achieved within 2-3 days. Clinical context: Twice-daily dosing provides consistent beta-blockade and vasodilation.
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, with less than 2% excreted unchanged in urine. Metabolites are excreted in bile and feces; renal clearance of metabolites accounts for ~16% of total clearance. Fecal excretion of metabolites is ~60%.
