IBUPROFEN AND FAMOTIDINE vs VIMOVO
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.
VIMOVO (esomeprazole and naproxen) is a fixed-dose combination. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), decreasing prostaglandin synthesis, thereby reducing inflammation, pain, and fever. Esomeprazole is a proton pump inhibitor (PPI) that suppresses gastric acid secretion by inhibiting the H+/K+ ATPase in gastric parietal cells. The combination is intended to reduce the risk of NSAID-associated gastric ulcers.
One tablet (ibuprofen 800 mg/famotidine 26.6 mg) orally three times daily.
One tablet (naproxen 500 mg/esomeprazole 20 mg) orally twice daily.

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).
Naproxen: 12-17 hours (prolonged in elderly and renal impairment; dosing interval typically 12 hours). Esomeprazole: 1-1.5 hours (metabolized by CYP2C19 and CYP3A4; no accumulation after repeated dosing).
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 50% as naproxen metabolites, <1% unchanged naproxen; less than 1% excreted unchanged in feces as esomeprazole; esomeprazole metabolites excreted in urine 80% and feces 20%.
