ADME/PK as part of a rational approach to drug discovery

Drug Discov Today. 2000 Sep;5(9):409-414. doi: 10.1016/s1359-6446(00)01540-3.


Rational drug discovery requires an early appraisal of all factors impacting on the likely success of a drug candidate in the subsequent preclinical, clinical and commercial phases of drug development. The study of absorption, distribution, metabolism, excretion and pharmacokinetics (ADME/PK) has developed into a relatively mature discipline in drug discovery through the application of well-established in vitro and in vivo methodologies. The availability of improved analytical and automation technologies has dramatically increased our ability to dissect out the fundamentals of ADME/PK through the development of increasingly powerful in silico methods. This is fuelling a shift away from the traditional, empirical nature of ADME/PK towards a more rational, in cerebro approach to drug design.
