ANAPROX vs CAMBIA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.

250-500 mg orally twice daily; maximum 1.5 g/day; for extended-release: 375-750 mg orally twice daily
50 mg orally once daily as needed for acute migraine, maximum 1 packet (50 mg) per 24 hours.

Terminal elimination half-life 12-17 hours; prolonged in elderly (up to 20 hours) and in renal impairment.
Terminal elimination half-life of diclofenac (active moiety) is approximately 1.9-2.1 hours. The clinical context: short half-life supports twice-daily dosing for acute pain.
Renal excretion of metabolites (95%) and unchanged drug (<5%); biliary/fecal elimination minor (<5%).
Approximately 50% of a dose is excreted in urine primarily as metabolites and conjugates, with less than 10% as unchanged drug. Biliary/fecal excretion accounts for about 40%.
