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.
Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that selectively inhibits cyclooxygenase-2 (COX-2), reducing prostaglandin synthesis involved in inflammation, pain, and fever. It has no significant inhibition of COX-1 at therapeutic doses.

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).
2-4 hours (terminal); clinical context: short half-life necessitates frequent dosing for sustained relief; prolonged in hepatic impairment
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: ~60% unchanged; biliary/fecal: ~30% as metabolites; remainder as glucuronide conjugates
