Abstract Amphetamines and methadone are synthetic chiral drugs with a high potential for abuse. As such, several analytical methods have been developed for their enantioseparation and analysis in biological tissues, and some of these are based on electrodriven techniques. In this review, the most important and recent of these latter methods are reviewed and their main advantages and disadvantages are discussed. Particular attention is paid to the suitability of each method for the application to the biological matrix of interest: while all methods have been successfully applied for one or more biological tissues, to reach this goal they must overcome the sensitivity problem that is common to almost all capillary electrophoretic techniques. Most methods use one or more cyclodextrin derivatives as the chiral selector, thus the separation mechanism is not particularly complicated or unusual.
