BROMFENAC SODIUM vs OMIDRIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing prostaglandin synthesis, leading to decreased inflammation, pain, and fever. Specifically, bromfenac is a potent inhibitor of COX-2.
OMIDRIA is a fixed-dose combination of ketorolac tromethamine, a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) activity, reducing prostaglandin synthesis, and phenylephrine hydrochloride, an alpha-1 adrenergic receptor agonist that causes vasoconstriction.
One drop (0.1 mL) of 0.09% ophthalmic solution (bromfenac 0.9 mg/mL) instilled into the affected eye(s) twice daily beginning 24 hours before cataract surgery and continuing on the day of surgery and for 14 days postoperatively.
1 mL of the fixed-dose combination (ketorolac 0.45% / phenylephrine 1%) administered intracamerally as a single dose at the time of cataract surgery.

Terminal elimination half-life: 1.5-2.5 hours (prolonged in renal impairment; clinical context: short half-life supports twice-daily dosing in ophthalmic use)
Ketorolac: terminal half-life of 5.3 hours (range 3.8-8.2 hours) in adults; phenylephrine: terminal half-life of 2-3 hours. Clinically, ketorolac's half-life supports twice-daily dosing.
Renal: ~80% (primarily as unchanged drug and glucuronide conjugate); Biliary/Fecal: ~20%
Renal elimination of ketorolac accounts for approximately 91% of the dose, with approximately 60% as unchanged drug and the remainder as metabolites; phenylephrine is primarily metabolized and excreted in urine as sulfate conjugates, with <20% excreted unchanged.
