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) enzymes, reducing prostaglandin synthesis and thereby alleviating inflammation, pain, and fever.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.
50 mg orally once daily as needed for acute migraine, maximum 1 packet (50 mg) per 24 hours.

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.
12–17 hours (terminal); allows twice-daily dosing; prolonged in elderly and renal impairment
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%.
Renal: 95% (as unchanged drug, conjugated naproxen, and 6-O-desmethyl naproxen); Fecal: <5%
