BETAGAN vs BREVIBLOC DOUBLE STRENGTH IN PLASTIC CONTAINER
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.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, myocardial contractility, and blood pressure by blocking catecholamine effects at beta-1 receptors.
Instill 1 drop of 0.25% or 0.5% solution into the affected eye(s) twice daily.
Intravenous: For stable patients, an initial loading dose of 500 mcg/kg/min over 1 minute followed by a maintenance infusion of 50 mcg/kg/min for 4 minutes; if response is inadequate, increase maintenance infusion to 100 mcg/kg/min and repeat loading dose after 10 minutes. Titrate in 50 mcg/kg/min increments up to 200 mcg/kg/min. For intraoperative and postoperative use, see full prescribing information.

Terminal elimination half-life is approximately 10-15 hours in adults; prolonged in renal impairment (up to 30 hours).
Terminal elimination half-life is approximately 9 minutes (range 8–10 minutes). Clinically, the half-life is consistent with rapid offset of effect upon discontinuation; steady state is achieved within 30 minutes of continuous infusion.
Primarily renal excretion of unchanged drug and metabolites; about 80% eliminated in urine, 20% in feces as unchanged drug or glucuronide conjugates.
Primarily metabolized by red blood cell esterases; <1% excreted unchanged in urine. Elimination is not dependent on renal or hepatic function.
