IBUPROFEN AND FAMOTIDINE vs MECLOMEN
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.
Meclomen (meclofenamate) is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. This results in anti-inflammatory, analgesic, and antipyretic effects.
One tablet (ibuprofen 800 mg/famotidine 26.6 mg) orally three times daily.
50-100 mg orally every 6-8 hours; maximum 400 mg/day.

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: 0.8–1.1 hours for meclofenamic acid; 2–4 hours for metabolites. Short half-life requires frequent dosing (e.g., every 6–8 hours) for sustained 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 (approximately 70% as metabolites, <5% unchanged); fecal/biliary (approximately 30% as metabolites).
