Ibuprofen isomers
WebbIbuprofen is a racemate. Its physicochemical properties and the short plasma-elimination half-life of the R(-) isomer, together with its limited ability to inhibit cyclo-oxygenase-1 (COX-1) and thus prostaglandin (PG) synthesis, compared with that of S(+)-ibuprofen, are responsible for the relatively low GI toxicity. Webb7 aug. 2008 · Because ibuprofen possesses an asymmetric carbon atom, it occurs as a dextro (+) or laevo (-) isomer.
