MYBULEN CAPSULES SCHEDULING STATUS: S3 PROPRIETARY NAME (and dosage form): MYBULEN CAPSULES COMPOSITION Each capsule contains: Ibuprofen 200,0 mg Paracetamol 250,0 mg Codeine Phosphate 10,0 mg PHARMACOLOGICAL CLASSIFICATION: A 2.8 Analgesic combinations. PHARMACOLOGICAL ACTION: Paracetamol has analgesic and antipyretic effects. Ibuprofen has analgesic, antipyretic and anti-inflammatory activities. Ibuprofen exerts its anti-inflammatory action peripherally in inflamed tissue by reducing prostaglandin activity and by inhibiting synthesis and/or actions of other local mediators of the inflammatory response. Codeine is metabolised to morphine, which in turn, exerts an analgesic effect. Pharmacokinetics: Paracetamol: Absorption following oral administration is rapid and almost complete. Paracetamol is metabolised in the liver primarily by conjugation. Paracetamol has a half-life of 1 to 4 hours, time to peak concentration of 0.5 to 2 hours, time to peak effect of 1 to 3 hours and a duration of action of 3 to 4 hours. Paracetamol is renally excreted primarily as metabolites and 3% of a dose may be excreted unchanged. Ibuprofen: Rapidly absorbed after oral administration. Onset of action for pain relief is 30 minutes and the time for peak effect for fever is 2 to 4 hours. The half-life of ibuprofen is about 2 hours and the duration of action for fever is 6 to 8 hours or more and is 4 to 6 hours for pain. More than 90% of an ingested dose is excreted in the urine as metabolites or their conjugates. Codeine: Readily absorbed from the gastrointestinal tract. Half-life is 2.5 to 4 hours. Codeine is metabolised in the liver. The cytochrome P450 enzyme 2D6 converts codeine to morphine, one of its metabolites. About 10% of the dose is demethylated to morphine.
