DICLOFENAC vs XIBROM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diclofenac inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
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.
Oral: 50 mg twice daily or 75 mg twice daily; maximum 150 mg/day. Topical: apply 4 times daily. IM: 75 mg once daily.
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 ~2 h (diclofenac immediate-release); enterohepatic recirculation may produce secondary peaks. Clinical context: Short half-life requires multiple daily dosing for sustained effect.
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 (65% as metabolites, <1% unchanged); biliary/fecal (35% as metabolites).
Renal: ~70% (primarily as unchanged drug); Biliary/Fecal: ~15% (as metabolites); the remainder is eliminated via other minor pathways.
