Cimicoxib (C16H13ClFN3O3S, Mr = 381.8 g/mol) is a chlorinated and fluorinated benzenesulfonamide and imidazole derivative. It has a V-shaped structure like other COX-2 inhibitors, which allows binding to the Active Site of the enzyme.

Effects

Cimicoxib (ATCvet QM01AH93) is analgesic, antipyretic, and anti-inflammatory. Its properties are based on selective and potent inhibition of the enzyme cyclooxygenase-2 (COX-2). In clinical trials, it showed comparable effects to firocoxib and carprofen.

Indications

For the treatment of pain and inflammation associated with osteoarthritis and for perioperative pain management in orthopedic and soft tissue surgery in dogs. Cimicoxib is not approved as a human drug. Clinical trials are underway to determine whether it is suitable for the treatment of depression and schizophrenia in humans.
