Pharmacological properties

NSAIDs, a derivative of propionic acid. It has analgesic, anti-inflammatory and antipyretic effects. The mechanism of action is associated with inhibition of prostaglandin synthesis at the level of cyclooxygenase. In addition, ketoprofen inhibits lipoxygenase, has anti-bradykinin activity, stabilizes lysosomal membranes, and inhibits the release of enzymes involved in the inflammatory process.

Ketoprofen does not adversely affect articular cartilage.


When applied topically, ketoprofen is absorbed slowly and practically does not accumulate in the body. Bioavailability is 5%. Ketoprofen penetrates well into the subcutaneous tissue, ligaments and muscles, synovial fluid and reaches therapeutic concentrations there. The concentration of the drug in blood plasma is extremely low. Ketoprofen is metabolized in the liver to form conjugates, which are mainly excreted in the urine.

Ketoprofen metabolism does not depend on age, the presence of severe renal failure or cirrhosis.

Use in the I and II trimesters is possible in cases where the expected benefit of therapy for the mother outweighs the potential risk to the fetus.

Drug interactions

Since the concentration of the drug in plasma is extremely low, manifestations of symptoms of interaction with other drugs (similar to symptoms with systemic use) are possible only with frequent and prolonged use.

The simultaneous use of other dosage forms (ointments, gels) containing ketoprofen or other NSAIDs is not recommended.

The simultaneous administration of acetylsalicylic acid reduces the degree of binding of ketoprofen to plasma proteins.

Ketoprofen reduces the excretion of methotrexate and contributes to an increase in its toxicity.

Interactions with other drugs and the effect on their elimination are not significant. When prescribing the drug to patients receiving coumarins, medical monitoring is recommended.
