PGH2, in turn, is converted by other enzymes to several other prostaglandins (which are mediators of pain, inflammation, and fever) and to thromboxane A2 (which stimulates platelet aggregation, leading to the formation of blood clots). Properties of [34][35], Along with other NSAIDs, ibuprofen has been associated with the onset of bullous pemphigoid or pemphigoid-like blistering. These enzymes include acyl-CoA-synthetase, which converts the R-enantiomer to ()-R-ibuprofen I-CoA; 2-arylpropionyl-CoA epimerase, which converts ()-R-ibuprofen I-CoA to (+)-S-ibuprofen I-CoA; and hydrolase, which converts (+)-S-ibuprofen I-CoA to the S-enantiomer. Ibuprofen is a relatively non-polar molecule, so it can be absorbed easily through the outer skin layer, but has difficulty penetrating the inner layer. All three compounds are aromatic.

A modern, greener technique for the synthesis involves only three steps.[59]. Compare the structure of the starting material, 2-methylpropylbenzene, with the desired product of the synthesis reactions, ibuprofen: The so-called "Green" synthesis of ibuprofen involves 3 steps2. The first is the aromatic group or Benzene ring in the centre of the structure. antipyretics (to reduce the body temperature when it is Also, because ibuprofen and the other antipyretic and anti-inflammatory over-the-counter medications treat the symptoms of fever and inflammation, taking these drugs before seeing a physician may mask important diagnostic clues. [6] Compared to other NSAIDs, it may have other side effects such as gastrointestinal bleeding. Generally, the symptoms observed with an overdose of ibuprofen are similar to the symptoms caused by overdoses of other NSAIDs. \end{align*} This decreases the formation of the precursors of prostaglandins, thus reducing the synthesis of prostaglandins, the main physiologic effect of ibuprofen. hbbd```b`` (d+L["r`+m"9" `RLlA5`\ oX|jWm;XD X6D20]g``?S+ j* It functions by inhibiting the action of the enzyme cyclooxygenase (COX)(COX)(COX) which is required for the synthesis prostaglandin H2(PGH2)H_{2}(PGH{_{2}})H2(PGH2) by the arachidonic acid pathway.
