a racemic mixture has 50-50% of the 2 different enantiomers. There are racemate drugs out there in the world. The misunderstanding I have is that usually 1 out of the 2 enantiomers molecules have a different reaction with the body, so if you perform racemisation to form a racemic mixture, ain’t that drug going to be still harmful in your body ? Or does FDA not accept racemic mixture where 1 of the enantiomers in it are harmful to the body? Thus they only accept racemic mixture where both enantiomers have to perform the same therapeutic effect on the body ?
