在EJ Ariens教授慷慨激昂地呼吁减少因忽视立体化学因素而引起的“药物动力学和临床药理学中复杂的废话”的扩散之后(Ariens, 1984),这个话题已经成为许多科学和监管辩论的主题。临床使用的60%以上的药物具有旋光性,大多数合成手性化合物以外消旋体形式给药。鉴于许多对映异构体的药理作用不同,主要问题是开发和规定单一异构体是否更可取。这个问题比另一个相关的问题更难回答,即如果使用外消旋体,是否要分离出单个对映体的动力学和动力学?只是随着最近改进的测量生物流体中异构体的技术的出现,才成为考虑这个问题的实际可能性。即便如此,分析任务的难度也不应被低估。此外,随着药物分子或药物代谢物中手性中心的数量增加,这项工作变得更加艰巨。药代动力学中的对映体特异性是由于在药物吸收、分布、代谢和排泄的一个或多个过程中对映体选择性而产生的。反过来,对映体选择性是手性药物与手性生物环境相互作用的结果。这次审查的目的是双重的。首先,指出对映体在吸收和处置现象方面的药代动力学差异的程度。其次,强调研究对映体特异性药代动力学的潜在好处,即基于测量单独异构体的时间过程而不是总外消旋药物混合物的动力学。
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.
