Indication

This combination tablet is indicated for the temporary relief of mild to moderate pain which has not been relieved by ibuprofen or paracetamol individually (such as migraine, headache, backache, menstrual pain, dental pain, rheumatic and joint pain, muscular pain, cold and flu symptoms, sore throat and fever).

Pharmacology

Paracetamol is a para-aminophenol derivative with analgesic and antipyretic properties and weak anti-inflammatory activity. It’s analgesic effect may include inhibition of central prostaglandin synthesis and modulation of inhibitory descending serotonergic pathways while its antipyretic property may be due to reduced production of prostaglandin in the hypothalamus. Ibuprofen is an NSAID which has analgesic, anti-inflammatory and antipyretic properties. It inhibits COX-1 and COX-2 enzymes, thereby also inhibiting prostaglandin synthesis.
