Abstract
Drug effects (pharmacodynamics) are determined by drug concentration at target site and the affinity of the drug for a target. Pharmacogenetics describes inherited differences in drug metabolising enzyme activities and differences in drug transporters and receptors.Answers were sought on the following questions:1. What is the value of genotyping on polymorphic drug metabolising enzymes compared to the classical phenotyping stategies?2. What is the situation concerning CYP2D6 and CYP2C19 polymorphism in the Dutch population?3. Is knowledge of the individual metaboliser status of CYP2D6 or CYP2C19 valuable in clinical pharmacological research and practice of pharmacotherapy
