Abstract
"PROCESSO PARA A PREPARAçãO DE UMA DISPERSãO ESTáVEL DE PARTìCULAS SóLIDAS EM UM MEIO AQUOSO, DISPERSãO ESTáVEL AQUOSA, PARTìCULA SóLIDA, COMPOSIçãO FARMACêUTICA, MéTODO PARA A INIBIçãO DO AMADURECIMENTO DE OSTWALD EM UMA DISPERSãO DE PARTìCULAS SóLIDAS SUBSTANCIALMENTE INSOLúVEIS EM áGUA EM UM MEIO AQUOSO, E, USO DE UM INIBIDOR". Um processo para a preparação de uma dispersão estável de partículas sólidas, em um meio aquoso, que compreende combinar (a) uma primeira solução, que compreende uma substância substancialmente insolúvel em água, um solvente orgânico miscível em água e um inibidor com (b) uma fase aquosa, que compreende água e opcionalmente um estabilizador, deste modo precipitando as partículas sólidas que compreendem o inibidor e a substância substancialmente insolúvel em água; e opcionalmente removendo o solvente orgânico miscível em água; em que o inibidor é um composto orgânico hidrofóbico não-polimérico, conforme definido na descrição. O processo provê uma dispersão de partículas sólidas em um meio aquoso, cujas partículas exibem um crescimento de partícula reduzido ou substancialmente nenhum crescimento de partícula mediado por amadurecimento de Ostwald.
