Active Ingredient History

  • Now
Diflunisal is a salicylic acid derivative with analgesic and anti-inflammatory activity. It was developed by Merck Sharp & Dohme in 1971 after showing promise in a research project studying more potent chemical analogs of aspirin. Diflunisal is an aspirin-like nonsteroidal anti-inflammatory drug that inhibits cyclooxygenase-2 (COX-2), an enzyme involved in prostaglandin synthesis.In animals, prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain. Since prostaglandins are known to be among the mediators of pain and inflammation, the mode of action of diflunisal may be due to a decrease of prostaglandins in peripheral tissues.   NCATS
