'''Non-steroidal anti-inflammatory agents''', also called '''non-steroidal anti-inflammatory drugs''' (NSAIDs) are defined as "anti-inflammatory agents that are not [[glucocorticoid|steroids]]. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They are used primarily in the treatment of chronic arthritic conditions and certain soft tissue disorders associated with [[pain]] and inflammation. They act by blocking the synthesis of [[prostaglandin]]s 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. Certain NSAIDs also may inhibit lipoxygenase enzymes or phospholipase C or may modulate T-cell function."<ref name="title-">{{cite web |url=http://www.nlm.nih.gov/cgi/mesh/2007/MB_cgi?term=Non-steroidal+anti-inflammatory+agents |title=Non-steroidal anti-inflammatory agents|author=National Library of Medicine |accessdate=2007-11-19 |format= |work=}}</ref>

Effectiveness

Combined with acetaminophen

For lumbalgia, acetaminophen one gram orally four times a day combined with diclofenac, a non-steroidal anti-inflammatory agent, was not better than acetaminophen alone in a randomized controlled trial.[1]

For reducing fever, acetaminophen combined with ibuprofen may be better than either drug alone according to a randomized controlled trial.[2]
