The three alternative animal tests now employed, the Fixed Dose Procedure, the Acute Toxic Class Method and the Up and Down Procedure, give rise to significant improvements in animal welfare. Although, the total replacement of animal tests it is not possible yet, basal cytotoxicity in vitro has been used as adjunct to these alternative animal tests to select initial doses, thus reducing the numbers of animals used during the evaluation of acute systemic toxicity.porAcesso AbertoToxicidade oral agudaMétodos alternativos de avaliação de toxicidadeCitotoxicidadeAcute toxicity evaluationAlternative methods of toxicity evaluationCytotoxicityAvaliação de toxicidade aguda: estratégias após a “era do teste DL50“Acute toxicity evaluation: strategies post “DL50 test era”Artigo10.5216/ref.v3i2.2083
