Sensory evaluation of albendazole suspensions
Sensory analysis was used in the albendazole suspension stability study. Three formulations were prepared and stored for 1, 3, and 6 months at 4 ±1, 26 ±1, 37, 50 and 65 ºC. Samples were evaluated through the difference from control sensory test using 24 trained judges in individual cabins. Although...

Zusammenfassung: | Sensory analysis was used in the albendazole suspension stability study. Three formulations were prepared and stored for 1, 3, and 6 months at 4 ±1, 26 ±1, 37, 50 and 65 ºC. Samples were evaluated through the difference from control sensory test using 24 trained judges in individual cabins. Although albendazole content was not altered in the conditions studied, sensory test showed differences between control and stored samples, except for one of the formulations stored under refrigeration for one month. These results have shown that the sensory evaluation is an important tool for quality control of pharmaceutical preparations, in association with chemical, physicochemical and microbiological tests.
Três formulações contendo albendazol foram preparadas e armazenadas por 6 meses nas temperaturas de 4± 1, 26±1, 37, 50 e 65 °C. Para avaliação sensorial aplicou-se o teste de diferença do controle, com a participação de 24 provadores treinados. Determinou-se o teor de albendazol por cromatografia líquida de alta eficiência utilizando como fase móvel etanol -tampão fosfato 0,05 M (70:30; v/v). Os resultados encontrados nesta pesquisa indicaram que a avaliação sensorial é importante no controle de qualidade de medicamentos além dos testes químicos, físico-químicos e microbiológicos. Este fato é evidente principalmente para preparações farmacêuticas de administração oral, uma vez que os aspectos sensoriais dos medicamentos podem influenciar o efeito terapêutico. O paciente pode não ingerir medicamentos que não apresentem atributos sensoriais agradáveis. |
