Biologia futura: animal testing in drug development—the past, the present and the future
Miklós Sántha
Abstract
Animal experiments have served to improve our knowledge on diseases and treatment approaches since ancient times. Today, animal experiments are widely used in medical, biomedical and veterinary research, and are essential means of drug development and preclinical testing, including toxicology and safety studies. Recently, great efforts have been made to replace animal experiments with in vitro organoid culture methods and in silico predictions, in agreement with the 3R strategy to "reduce, refine and replace" animals in experimental testing, as outlined by the European Commission. Here we present a mini-review on the development of animal testing, as well as on alternative in vitro and in silico methods, that may at least partly replace animal experiments in the near future.
