Non-steroidal anti-inflammatory agents, also called non-steroidal anti-inflammatory drugs (NSAIDs) are defined as "anti-inflammatory agents that are not 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 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. Certain NSAIDs also may inhibit lipoxygenase enzymes or phospholipase C or may modulate T-cell function."[1]
Classification
Non-selective inhibitors of clooxygenase
These drugs inhibit both cyclooxygenase isozymes.
Selective inhibitors of cyclooxygenase 2
Adverse reactions
Gastrointestinal
NSAIDs may contribute to gastrointestinal ulceration including peptic ulcer disease.
Renal
NSAIDs may cause acute kidney injury due to acute tubular necrosis. This may rarely occur after just a few doses.[2]
