OPTICAL ISOMER OF PHENYLPROPIONIC ACID AND ITS MEDICINAL USE

摘要

Optical isomers of phenylpropionic acid drugs are a mixture having R-type optical isomer and S-type optical isomer at a ratio of 10:1-1:10 by weight, wherein the ratio of 1:1 is excluded. A use of the optical isomers includes that the R-type optical isomer is used for manufacturing anti-inflammatory and analgesic drugs and the mixture having the R-type optical isomer and the S-type optical isomer at a ratio of 10:1-1:10 by weight, wherein the ratio of 1:1 is excluded, is used for manufacturing anti-inflammatory and analgesic drugs. The therapeutic indexes of anti-inflammatory and analgesic drugs of the present optical isomers are all higher than those of the S-type optical isomers and the racemate.
