Safety pharmacology: an essential interface of pharmacology and toxicology in the non-clinical assessment of new pharmaceuticals

Abstract

Safety pharmacology studies are defined as the studies that investigate the potential undesirable pharmacodynamic effects of a substance on physiological functions in relation to exposure. In consequence, these studies are an integral part of the non-clinical safety assessment of new pharmaceuticals, in association with toxicological studies. A retrospective shows the evolution of the discipline in these last years. Safety pharmacology studies are of special interest, and some drawbacks and pitfalls must be considered (i.e. invasive methods, difficulties related to GLP (good laboratory practices) requirements, choice of a strategy). In the future, some priority should be given to education, promotion of scientific activities, reinforcement of the links between pharmacologists and toxicologists and implementation of relevant guidelines.
