EC-NAPROSYN vs XIBROM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
XIBROM (bromfenac) is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing intraocular inflammation.
500-1000 mg orally twice daily; maximum 1500 mg/day.
Instill 1 drop into the affected eye(s) 4 times daily starting 24 hours before surgery and continuing for 2 weeks postoperatively.

Terminal elimination half-life 12-17 hours (mean 14 hours); prolonged in elderly and renal impairment
Terminal elimination half-life is approximately 42 hours. Clinical context: Due to its long half-life, steady-state is achieved after about 8 days of daily dosing, which contributes to sustained anti-inflammatory effect.
Renal (95%) as unchanged drug (10%) and conjugated metabolites (60%) and other metabolites (25%); biliary/fecal (5%)
Renal: ~70% (primarily as unchanged drug); Biliary/Fecal: ~15% (as metabolites); the remainder is eliminated via other minor pathways.
