IBUPROFEN AND FAMOTIDINE vs XIBROM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, which decreases inflammation, pain, and fever. Famotidine is a histamine H2-receptor antagonist that inhibits gastric acid secretion by blocking histamine at H2 receptors on gastric parietal cells.
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.
One tablet (ibuprofen 800 mg/famotidine 26.6 mg) orally three times daily.
Instill 1 drop into the affected eye(s) 4 times daily starting 24 hours before surgery and continuing for 2 weeks postoperatively.

Ibuprofen: Terminal half-life 2-4 hours (normal renal function); prolonged to 3-6 hours in elderly or hepatic impairment. Famotidine: Terminal half-life 2.5-3.5 hours (normal renal function); extended to >20 hours in severe renal impairment (CrCl <10 mL/min).
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.
Ibuprofen: Renal excretion of metabolites (90%) and unchanged drug (<10%); biliary/fecal (minor). Famotidine: Renal excretion of unchanged drug (65-70%); metabolites (25-30%); biliary/fecal (minor).
Renal: ~70% (primarily as unchanged drug); Biliary/Fecal: ~15% (as metabolites); the remainder is eliminated via other minor pathways.
