ACTRON vs FLURBIPROFEN 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 cyclooxygenase (COX-1 and COX-2) inhibitor, thereby decreasing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Oral: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/day.
50 mg orally every 4 to 6 hours as needed; maximum 300 mg per day.

Terminal elimination half-life 2-4 hours; prolonged to 6-12 hours in elderly or renal impairment (CrCl <30 mL/min).
3-4 hours; in elderly or hepatic impairment may extend to 5-6 hours.
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
