Erythropoiesis-stimulating agents: development, detection and dangers

Epoetin alfa, the first member of the family of erythropoiesis stimulating agents (ESAs), was introduced to the market in 1989. Since then development has progressed to epoetins of the third generation. Currently drugs that use alternative approaches to stimulate erythropoiesis are under development. Uptake of all available ESAs into doping has occurred rapidly after their introduction. A multitude of dangers to health are associated with the illicit use of these substances. Different approaches to detect ESAs in doping control have been developed to comply with the very diverse nature of the compounds used. Future developments in the field of ESA require the development of new techniques in doping analysis. This review gives an overview of the development of ESA and its detection methods as well as future developments.
