Ibuprofen pills 200mg №50

Mechanism of action

NSAID, a derivative of phenylpropionic acid. It has anti-inflammatory, analgesic and antipyretic effects.
The mechanism of action is associated with inhibition of the activity of COX - the main enzyme in the metabolism of arachidonic acid, which is a precursor of prostaglandins, which play a major role in the pathogenesis of inflammation, pain and fever. The analgesic effect is due both to the peripheral (indirectly, through suppression of prostaglandin synthesis) and to the central mechanism (due to inhibition of the synthesis of prostaglandins in the central and peripheral nervous system). Suppresses platelet aggregation.

When ingestion ibuprofen is almost completely absorbed from the gastrointestinal tract. Simultaneous food intake slows down the rate of absorption. Metabolized in the liver (90%). The half-life is 2-3 hours.
80% of the dose is excreted in the urine mainly in the form of metabolites (70%), 10% - unchanged; 20% is excreted through the intestines as metabolites.
