“…Models can in turn make use of in silico predictions of transfer subprocesses or model parameters (based on e.g. physicochemical properties) as well as in vitro and ex vivo laboratory models (8) (providing information on tissue distribution and metabolism); this may become necessary to predict the transfer of substances for which little or no animal experimental data are available. Toxicokinetic models thus extract transfer information from those data and allow extrapolation to describe other situations of interest with a relatively small amount of additional data (9) .…”

“…Uma das vantagens da utilização destas técnicas é alcançar a redução do tempo e os custos experimentais. Devido ao menor custo envolvido, essas metodologias são, no geral, utilizadas em casos onde o uso in vivo é inapropriado, devido ao risco para os animais (Klevenhusen et al, 2021), ou como um experimento preliminar (Kent-Dennis et al, 2020), pois fornece os resultados mais rapidamente (Oliveira et al, 2014). Além disso, quando as metodologias in vitro são empregadas, os pesquisadores podem reduzir significativamente o número total de animais utilizados, já que apenas a coleta de inóculo é necessária, em vez de conduzir longos ensaios de digestibilidade ou produção de gases com um grande grupo para estudos in vivo, visto que as amostras podem ser coletadas de um pequeno número de animais canulados (Vinyard e Faciola, 2022).…”
