Abstract

"MéTODOS PARA PRODUçãO DE FORMULAçõES FARMACêUTICAS QUE COMPREENDEM MICROPARTìCULAS AGLOMERADAS". São fornecidos métodos para produção de formulação farmacêutica de mistura em pó seco que compreendem (i) formação de micropartículas que compreendem um agente farmacêutico; (ii ) o fornecimento de pelo menos um excipiente na forma de partículas tendo um diâmetro médio de volume que é maior que o diâmetro médio de volume das micropartículas; (iii) mistura das micropartículas com o excipiente para formar uma mistura em pó; e (iv) moagem em jato da mistura em pó para desaglomerar pelo menos uma porção de quaisquer das micropartículas que se aglomeraram, embora mantenha substancialmente o tamanho e morfologia das micropartículas individuais. A moagem em jato pode eliminar de forma vantajosa a necessidade por processos de desaglomeração úmidos mais complicados, pode diminuir os níveis de umidade residual e de solvente nas micropartículas (que leva a melhor estabilidade e propriedades de manuseio para formulações em pó seco) , e pode melhorar a capacidade de umedecimento, capacidade de suspensão, e uniformidade de conteúdo de formulações de mistura em pó seco.
