O presente trabalho discute a avaliacao da toxicidade aguda sistemica apos a eliminacao do teste da DL50 (dose letal mediana). Os tres testes alternativos em animais empregados hoje, Dose Fixa, Toxicidade Aguda de Classe e o Teste “Up and Down”, trouxeram significante melhora para o bem-estar animal. Embora a eliminacao total do uso de animais ainda nao seja possivel, a citotoxicidade basal in vitro tem sido empregada como adjuvante dos testes em animal para a selecao das doses iniciais reduzindo ainda mais o numero de animais empregados na avaliacao do toxicidade aguda sistemica. 10.5216/ref.v3i2.2083
