As time lines for drug discovery, testing and approval are compressed, the importance of planning and effective teamwork across scientific disciplines increases.The role of the regulatory professional at the interface of numerous scientific and legal disciplines also becomes more critical to successful drug development.Experience as a chemist can provide a strong science background and anal. thinking skills which are valuable tools in regulatory work.A knowledge of chem. is also directly applicable to addressing the regulatory aspects of many areas of drug development such as drug design, synthesis, formulation, manufacturing, quality testing, and measurement of drugs and metabolites in humans and animals.This presentation will breifly describe the role of chem. in regulatory and the role of regulatory in drug development, using the example of one chemist′s transition from the laboratory to regulatory.
