DIFLUNISAL vs XIBROM
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) enzymes, 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.
500 mg to 1000 mg orally initially, then 250 mg to 500 mg every 8 to 12 hours. Maximum daily dose: 1500 mg.
Instill 1 drop into the affected eye(s) 4 times daily starting 24 hours before surgery and continuing for 2 weeks postoperatively.

8-12 hours (prolonged in renal impairment; clinical context: permits twice-daily dosing)
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 (90% as glucuronide conjugates, <5% unchanged); biliary/fecal (<10%)
Renal: ~70% (primarily as unchanged drug); Biliary/Fecal: ~15% (as metabolites); the remainder is eliminated via other minor pathways.
