ACETAMINOPHEN AND IBUPROFEN vs IBUPROHM COLD AND SINUS
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.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to anti-inflammatory, analgesic, and antipyretic effects. Pseudoephedrine is a sympathomimetic amine that acts as a vasoconstrictor via alpha-adrenergic receptors in nasal mucosa, reducing nasal congestion.
Oral: Acetaminophen 325 mg and ibuprofen 200 mg, 1-2 tablets every 6 hours as needed, not exceeding 6 tablets/24 hours.
1-2 tablets (each containing ibuprofen 200 mg and pseudoephedrine 30 mg) orally every 4-6 hours as needed; maximum daily dose: 6 tablets (ibuprofen 1200 mg, pseudoephedrine 180 mg).

Acetaminophen: 2-3 hours (normal hepatic function). Ibuprofen: 2-4 hours (immediate-release); prolonged in overdose or hepatic impairment.
1.8–2.5 hours in adults; prolonged to 3–4 hours in elderly or hepatic impairment due to reduced clearance.
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.
Renal excretion of unchanged drug and metabolites accounts for >90% of elimination, with approximately 1% excreted as unchanged ibuprofen. Biliary/fecal excretion is <10%.
