ACETAMINOPHEN AND IBUPROFEN vs INDICLOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetaminophen is a centrally acting analgesic and antipyretic whose exact mechanism is not fully understood, but is thought to involve inhibition of cyclooxygenase (COX) in the brain and modulation of cannabinoid receptors. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that non-selectively inhibits COX-1 and COX-2, reducing prostaglandin synthesis.
Alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription.
Oral: Acetaminophen 325 mg and ibuprofen 200 mg, 1-2 tablets every 6 hours as needed, not exceeding 6 tablets/24 hours.
INDICLOR is not a recognized drug; no standard dosing available.

Acetaminophen: 2-3 hours (normal hepatic function). Ibuprofen: 2-4 hours (immediate-release); prolonged in overdose or hepatic impairment.
Terminal elimination half-life is 12 hours (range 10-15 hours) in patients with normal renal function; prolonged in renal impairment (up to 25 hours in severe cases).
Acetaminophen: renal excretion of metabolites (glucuronide 55%, sulfate 30%, cysteine/mercapturate <10%); <5% unchanged. Ibuprofen: renal excretion of metabolites (conjugates) 90%; <10% unchanged; minor biliary/fecal.
Primarily renal excretion (approximately 70% unchanged drug); biliary/fecal excretion accounts for about 10-15% as metabolites.
