ACTRON vs IBUPROHM COLD AND SINUS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetaminophen (paracetamol) is a non-opioid analgesic and antipyretic. Its mechanism is not fully understood but involves inhibition of cyclooxygenase (COX) enzymes in the central nervous system, reducing prostaglandin synthesis. It also modulates the endocannabinoid system and serotonergic pathways.
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: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/day.
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).

Terminal elimination half-life 2-4 hours; prolonged to 6-12 hours in elderly or renal impairment (CrCl <30 mL/min).
1.8–2.5 hours in adults; prolonged to 3–4 hours in elderly or hepatic impairment due to reduced clearance.
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
Renal excretion of unchanged drug and metabolites accounts for >90% of elimination, with approximately 1% excreted as unchanged ibuprofen. Biliary/fecal excretion is <10%.
