Pharmacology
Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic actions. In addition to the inhibition of prostaglandin synthesis, it stabilizes lysosomal membranes in vitro and in vivo, inhibits leukotriene synthesis in vitro at high concentrations, and also exhibits antibradykinin activity in vivo. Ketoprofen produces analgesia by inhibiting the synthesis of prostaglandins peripherally and centrally. It has also been suggested that Ketoprofen causes the suppression of prostaglandin synthesis in the CNS (probably in the hypothalamus) leading to its antipyretic effect.
