WebbIbuprofen is an interesting case, in that the (5)- (+)-form is an active analgesic, but the ( )- (—)-enantiomer is inactive. However, in the body there is some metabolic conversion of the inactive (I )-isomer into the active (5 )-isomer, so that the potential activity from the racemate is considerably more than 50%.
