The future lies in chiral purity: a perspective.
Racemates are fixed-dose combinations of stereoisomers. Each isomer may have different pharmacokinetic or pharmacodynamic properties. Recent research has allowed appreciation of the need to purify racemates and develop useful unichiral molecules. Some examples are: S-amlodipine besylate, S-atenolol, S-metoprolol succinate, S-pantoprazole sodium and R-ondansetron hydrochloride.
