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, thereby reducing the synthesis of prostaglandins involved in pain, inflammation, and fever.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis.
400 mg (two 200 mg Liqui-Gels) orally every 6 to 8 hours as needed; maximum 1200 mg per day.
550 mg orally every 8 to 12 hours; maximum 1375 mg/day.

Terminal elimination half-life is approximately 2 hours (range 1.8–3.5 hours). In clinical context, this short half-life supports dosing every 4–6 hours for acute migraine treatment, but drug effects may persist beyond this due to slow dissociation from COX enzymes.
Terminal elimination half-life is approximately 12–17 hours (mean ~14 hours), allowing twice-daily dosing. Steady-state is achieved after 4–5 doses.
Renal excretion of unchanged drug and metabolites accounts for approximately 90% of an administered dose, with about 10% excreted in feces via bile. Less than 1% is excreted unchanged in urine; the remainder as conjugates and oxidative metabolites.
Renal elimination of naproxen and its metabolites accounts for approximately 95% of the dose, with about 60% as unchanged drug and 40% as conjugated or hydroxylated metabolites. Biliary/fecal excretion is negligible (<5%).
