ACTRON vs Ibuprofen
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 inhibition of cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to anti-inflammatory, analgesic, and antipyretic effects.
Oral: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/day.
200-800 mg orally every 6-8 hours; maximum 3200 mg/day.

Terminal elimination half-life is 2-4 hours; no accumulation with repeated dosing in normal renal function.
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
Renal excretion of conjugated metabolites (about 90% as glucuronide and sulfate conjugates, <10% as unchanged drug); minor biliary/fecal elimination (<5%).
