Pharmacology

This is a combination of Paracetamol and Caffeine. Paracetamol has analgesic and antipyretic properties with weak anti-inflammatory activity. Caffeine is an alkaloid which is a theophylline-like xanthine derivative. By intermolecular association with Paracetamol, Caffeine increases the solubility and transmembrane permeation of Paracetamol. In addition, Caffeine increases the pain threshold and tolerance of pain. Caffeine has also an intrinsic power to raise vessel tone in the brain, which provides another benefit to treat migraine and headache.

Dosage & Administration

Adult dose: 1-2 tablets every 4-6 hours. Maximum dose: 8 tablets daily.

Child dose: Not recommended for children below 12 years.
