• Carprofen is a non-steroidal anti-inflammatory drug (NSAID) of the propionic acid class that includes ibuprofen, naproxen, and ketoprofen. It is no longer used in the clinical setting, but is approved for use in dogs. Carprofen is non-narcotic and has characteristic analgesic and antipyretic activity approximately equipotent to indomethacin in animal models.

Documented Uses

• Animal Drugs -> FDA Approved Animal Drug Products (Green Book) -> Active Ingredients
• Pharmaceuticals -> Animal Drugs -> Approved in Taiwan
• For use as a pain reliever in the treatment of joint pain and post-surgical pain.
• Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
• Drugs that are pharmacologically inactive but when exposed to ultraviolet radiation or sunlight are converted to their active metabolite to produce a beneficial reaction affecting the diseased tissue. These compounds can be administered topically or systemically and have been used therapeutically to treat psoriasis and various types of neoplasms.
