EC-NAPROSYN vs INDOMETHACIN
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.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.
500-1000 mg orally twice daily; maximum 1500 mg/day.
25-50 mg orally 2-3 times daily; maximum 200 mg/day. Also available as 75 mg sustained-release capsule orally once daily, or 50 mg rectally 3-4 times daily.

Clinical Note
moderateIndomethacin + Trovafloxacin
Terminal elimination half-life is approximately 4.5 hours (range 2.6-11.2 hours) in adults; prolonged in neonates (up to 17 hours) and in patients with renal impairment or cholestasis; clinical context: dosing interval adjustments needed in hepatic or renal disease.
Renal (95%) as unchanged drug (10%) and conjugated metabolites (60%) and other metabolites (25%); biliary/fecal (5%)
Renal excretion of unchanged drug and metabolites (approximately 60% as parent drug and glucuronide conjugate; 23% as O-desmethyl metabolite; 13% as glucuronide of O-desmethyl metabolite); biliary/fecal elimination accounts for 30-40%, primarily as glucuronide conjugates.
