Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby decreasing pain, fever, and inflammation.
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.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day without prescription, extended release forms: 600-800 mg orally twice daily.
One tablet (ibuprofen 800 mg/famotidine 26.6 mg) orally three times daily.

2-4 hours in children; prolonged in neonates and hepatic impairment.
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).
Renal (90%) as inactive metabolites and conjugates; fecal (<5%).
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).
