Following an impassioned plea from Professor EJ Ariens to curtail the proliferation of'sophisticated nonsense in pharmacokinetics and clinical pharmacology'arising from the neglect of stereochemical factors (Ariens, 1984), this topic has been the subject of much scientific and regulatory debate. Over 60% of drugs in clinical use are optically active and a majority of the synthetic chiral compounds are administered as racemates. Given that many enantiomers differ in their pharmacological effects the main issue is whether it is preferable to develop and prescribe single isomers. This question is rather more difficult to answer than a related one, namely that if a racemate is used whether to dissect out the kinetics and dynamics of the individual enantiomers? It is only with the very recent advent of improved technology for measuring isomers in biological fluids that it becomes a practical possibility to consider this problem. Even so, the difficulty of the analytical task should not be underestimated. Moreover, as the number of chiral centres in a drug molecule, or in the metabolite of a drug, increases the more formidable the exercise becomes.Enantiospecificity in pharmacokinetics arises because of enantioselectivity in one or more of the processes of drug absorption, distribution, metabolism and excretion. In turn, enantioselectivity results from the interaction of chiral drugs with a chiral biological milieu. The aims of this review are twofold. Firstly, to indicate the extent of differences in the pharmacokinetics of enantiomers with respect to absorption and disposition phenomena. Secondly, to emphasise the potential benefits of studying enantiospecific pharmacokinetics, that is, kinetics based on the measurement of the time-course of separate isomers rather than of the total, racemic drug mixture.
