How Does Ketoprofen Work?

Ketoprofen works as an NSAID by inhibiting the COX-1 and COX-2 enzymes, which produce prostaglandins that cause inflammation, pain, and fever. By reducing prostaglandins, ketoprofen decreases inflammation, lessens pain, and lowers fever. It may also inhibit lipoxygenase enzymes, adding to its anti-inflammatory effects, and has some central nervous system action for pain relief. Ketoprofen is rapidly absorbed, reaching peak levels in 0.5 to 2 hours, but has a short half-life of about 2 hours, requiring frequent dosing. It is highly protein-bound in plasma, affecting its distribution and elimination.
