How does the remedy work?

The active ingredient paracetamol primarily has an analgesic and fever lowering effect. This effect arises from the inhibition of the production of prostaglandins (messenger substances). In contrast to other painkillers such as non-steroidal anti-inflammatory drugs (NSAIDs), Mexalen has only a weak anti-inflammatory effect, but is better tolerated by the stomach. Paracetamol is broken down in the liver and excreted mainly in the urine.
