Diclofenac Sodium Injection
Diclofenac is a non steroidal anti-inflammatory and analgesic drug derived from phenylacetic acid. Its mechanism of action is to inhibit the activity of cyclooxygenase, thus blocking the transformation of arachidonic acid into prostaglandins. At the same time, it can also promote the combination of arachidonic acid and triglyceride (triacylglycerol), reduce the concentration of free arachidonic acid in cells, and indirectly inhibit the synthesis of leukotrienes. Diclofenac is one of the most effective non steroidal anti-inflammatory drugs. Its inhibitory effect on prostaglandin synthesis is stronger than that of aspirin and indomethacin.
