Ibuprofen is a nonsteroidal anti-inflammatory drug used worldwide to control pain, fever and inflammation.Oral intake of Ibuprofen produces a hypoalgesic effect due to biochemical inhibition of the COX enzymes, which convert arachidonic acid to prostaglandin H2 (PGH2). PGH2, which in turn, is converted by other enzymes to several types of prostaglandins and thromboxanes (which are mediators of pain and inflammation).
