Resumen
A contaminação por endotoxinas é uma ameaça à segurança dos produtos farmacêuticos, especialmente dos medicamentos parenterais. Qualquer produto farmacêutico estéril e/ou livre de pirogênios requer especificações regulatórias para garantir a segurança de uso para o paciente. Este estudo abrange o estudo de avaliação de desempenho empregando o kit comercial Endozyme II® Go para quantificação de endotoxina, por Fator C recombinante (FCr), em amostras de cloreto de sódio 0,9% para uso parenteral. As amostras foram fortificadas com cinco concentrações distintas de soluções de endotoxina na faixa entre 0,0005 e 10 UE/mL. Cada um dos cinco níveis foi testado pelo menos cinco vezes para avaliação dos critérios de precisão, exatidão, limites de detecção e quantificação, linearidade e robustez. O desvio padrão relativo para os testes de precisão variou de 1,9 a 8,3%. Os valores de recuperação de endotoxina para o parâmetro exatidão estiveram compreendidos entre 61% e 125%. Os resultados demonstraram que o método por FCr permite a quantificação de endotoxinas com exatidão, precisão, especificidade e linearidade para a faixa de 0,005 e 10 UE/mL em amostras de cloreto de sódio 0,9% para uso parenteral.
