Evaluation of the activity of albendazole in the therapy of experimentally-infected rats

Abstract

In order to settle the precise spectrum of activity of albendazole, its efficacy was tested in the treatment of Strongyloides venezuelensis in experimentally-infected rats. The results were compared to those obtained with two other benzimidaloze derivatives, cambendazole and mebendazole. The three compounds were shown to be effective in eradicating intestinal adult worms completely, when single doses of 625, 12.5, 25 of 50 mg/kg were used. However when smaller doses were employed (5 mg/kg) worm burdens were reduced in 87%, 98% and 80% by albendazole, cambendazole and mebendazole respectively.Com a finalidade de demarcar mais precisamente o espectro de ação do albendazol, foi estudada a atividade terapêutica desse anti-helmíntico em ratos experimentalmente infectados com Strongyloides venezuelensis, tendo sido usada, como termo de comparação, a ação do cambendazol e do mebendazol, dois outros benzimidazólicos. Os três compostos mostraram-se eficientes quando utilizadas doses únicas de 6,75, 12,5, 25 e 50 mg/kg, pois motivaram desaparecimento total das formas adultas no intestino. Com a posologia de 5 mg/kg sucederam porcentagens médias de reduções dos números de vermes de 87%, 98% e 80%, respectivamente, como decorrência do emprego do albendazol, do cambendazol e do mebendazol, traduzindo superioridade da segunda droga citada
