Inflamnation is mediated by prostaglandins produced by the cyclooxygenase pathway.
NSAIDs inhibit this pathway and serve as combined anti - inflammatory , antipyretics and analgesics .
NSADs are often classified on the basis of their chemical structure.
• Salicylates : aspirin, diflunisal, 5- aminosalicylate , sodium salicylate , magnesium salicylate , sulfasalazine , olasalzine.
• Acetic acids : indomethacin , diclofenac , sulindac , etodolac, ketorolac ,tolmetin.
• propionic acids : ibuprofen , naproxen, fenoprifen , ketoprofen, flurbiprofen, oxaprozin.
• Fenamic acids : meclofenamate, mefenamate.
• Enolic acids : piroxicam
• Ketones : nabumetone.
