Abstract
Abstract An ibuprofen-containing medicament which contains ibuprofen only in the (S)-(+)-form is disclosed. (S)-(+)-ibuprofen is more than twice as active as the racemate which has until now been used in the treatment of rheumatism. This permits reduction of the quantity of active ingredient and the size of the tablets or dragees.
