Mechanism of Action

The exact mechanism of action of Orudis is unknown. It is thought to work by inhibiting the synthesis of prostaglandins, which are chemicals that play a role in pain and inflammation.


Orudis is rapidly absorbed from the gastrointestinal tract. The bioavailability of Orudis is approximately 50%. The peak plasma concentration is reached within 1-2 hours. Ketoprofen is 97% bound to plasma proteins.


The elimination half-life of ketoprofen ranges from 4 to 6 hours.


Ketoprofen is metabolized in the liver by cytochrome P450 enzymes, specifically by CYP2C9. The primary metabolites are hydroxyketoprofen, ketoprofen glucuronide, and 5-hydroxyketoprofen glucuronide.


Ketoprofen and its metabolites are excreted mainly in the urine. Less than 2% of the dose is excreted in the feces.
