Abstract
Pharmacokinetics refers to the effects the body has upon a consumed drug, by considering a variety of processes which a dug undergoes during its time within the body. In contrast pharmacodynamics can be considered as the effects a drug has upon the body that has consumed it, by considering the drug’s effects at its principal sites of action. Safe and effective therapeutic management of drugs for individual patients requires application of pharmacokinetic and pharmacodynamic principles to enhance efficacy and minimize toxicity. Chapter 5 (Pharmacogenomics and Psychopharmacology) provides a detailed review of the genes relevant for drug absorption, distribution, metabolism and excretion. As such these issues are only dealt with briefly in this chapter.
