CHILDREN'S MOTRIN vs MEASURIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby decreasing pain, fever, and inflammation.
Measurin is an aspirin preparation that irreversibly inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin and thromboxane synthesis. This results in analgesic, antipyretic, anti-inflammatory, and antiplatelet effects.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day without prescription, extended release forms: 600-800 mg orally twice daily.
325-650 mg orally every 4-6 hours as needed; maximum 4 g/day.

2-4 hours in children; prolonged in neonates and hepatic impairment.
Plasma elimination half-life is 2-3 hours at low doses (antiplatelet) and increases to 15-30 hours at anti-inflammatory doses due to saturation of hepatic metabolism; clinical context: higher doses require longer dosing intervals to avoid accumulation.
Renal (90%) as inactive metabolites and conjugates; fecal (<5%).
Renal excretion of salicylate and its metabolites (salicyluric acid, salicyl phenolic glucuronide, salicyl acyl glucuronide, gentisic acid) accounts for >90% of elimination; minor biliary/fecal excretion (<5%) occurs.
