ACTRON vs IBUPROFEN SODIUM
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.
Non-selective inhibitor of cyclooxygenase (COX-1 and COX-2), decreasing prostaglandin synthesis, resulting in anti-inflammatory, analgesic, and antipyretic effects.
Oral: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/day.
200-400 mg orally every 4-6 hours, maximum 1200 mg/day; for OTC use, 200-400 mg every 6-8 hours as needed, maximum 1200 mg/day.

Terminal elimination half-life 2-4 hours; prolonged to 6-12 hours in elderly or renal impairment (CrCl <30 mL/min).
2.0-2.5 hours (terminal); no prolongation in mild hepatic impairment; increased in renal failure.
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
