ANAPROX DS vs HYDROCODONE BITARTRATE AND IBUPROFEN
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.
Hydrocodone is a semisynthetic opioid agonist with selectivity for mu-opioid receptors, producing analgesia and sedation. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby providing anti-inflammatory, analgesic, and antipyretic effects.
550 mg orally every 8 to 12 hours; maximum 1375 mg/day.
One tablet (hydrocodone bitartrate 5 mg/ibuprofen 200 mg) orally every 4 to 6 hours as needed for pain; maximum 5 tablets per day.

Terminal elimination half-life is approximately 12–17 hours (mean ~14 hours), allowing twice-daily dosing. Steady-state is achieved after 4–5 doses.
Hydrocodone: 3.8-4.5 hours (immediate release); Ibuprofen: 1.8-2.5 hours (racemic, S-enantiomer slightly shorter). Clinical context: dosing every 4-6 hours due to hydrocodone half-life.
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%).
Hydrocodone: primarily renal (60-70% as metabolites, <12% unchanged); Ibuprofen: primarily renal (90% as metabolites and conjugates, <1% unchanged), minor biliary/fecal.
