EC-NAPROSYN vs IBUPROFEN LYSINE
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-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Ibuprofen lysine is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This results in anti-inflammatory, analgesic, and antipyretic effects.
500-1000 mg orally twice daily; maximum 1500 mg/day.
200-800 mg orally every 6-8 hours as needed; maximum 2400 mg/day. Intravenous: 400-800 mg every 6 hours; maximum 3.2 g/day.

Terminal elimination half-life 12-17 hours (mean 14 hours); prolonged in elderly and renal impairment
2–4 hours in adults; extended to 4–6 hours in neonates. In severe hepatic or renal impairment, half-life may increase up to 8–10 hours.
Renal (95%) as unchanged drug (10%) and conjugated metabolites (60%) and other metabolites (25%); biliary/fecal (5%)
Renal excretion of metabolites and conjugates accounts for >90% of elimination; less than 1% is excreted unchanged in urine. Fecal excretion is minimal (<5%).
