1. Anti-Inflammatory Agents, Non-Steroidal 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. 2. Cyclooxygenase Inhibitors Compounds or agents that combine with cyclooxygenase and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes. 3. Gout Suppressants Agents that increase uric acid excretion by the kidney, decrease uric acid production (antihyperuricemics), or alleviate the pain and inflammation of acute attacks of gout. |
