Ketoprofen uses

Pharmacological action

Ketoprofen is a NSAID, propionic acid derivative. This medication has analgesic, anti-inflammatory and antipyretic activity. The mechanism of action is associated with inhibition of COX activity - the main enzyme metabolism of arachidonic acid, a precursor of prostaglandins, which play a major role in the pathogenesis of inflammation, pain and fever. A pronounced analgesic effect of Ketoprofen is due to two mechanisms: peripheral and central (due to inhibition of prostaglandin synthesis in the central and peripheral nervous system, as well as the influence on the biological activity of other neurotrophic substances that play a key role in the release of neurotransmitters in the spinal pain brain). In addition, this drug has anti-bradykinin activity, stabilizes lysosomal membranes, causes a significant inhibition of neutrophils in patients with rheumatoid arthritis.

Cmax in plasma by ingestion is achieved through 1-5 hours (depending on dosage form), with rectal administration - after 45-60 min; IM administration - after 20-30 min; IV injections - after 5 minutes.
