Abstract

<B>SISTEMAS LIQUISSóLIDOS E MéTODOS DE PREPARAçãO DOS MESMOS<D>. Sistemas liquissólidos são formas em pó aceitavelmente fluentes e compressíveis de medicações líquidas. De acordo com o conceito de sistemas liquissólidos, drogas lipofílicas líquidas ou drogas insolúveis em água dissolvidas em solventes não voláteis adequados podem ser convertidas em pós facilmente compressíveis e de fluxo livre mediante mistura simples com excipientes em pó selecionados referidos como materiais portador e de revestimento; um esboço esquemático das etapas pode ser traçado para o processo. Vários tipos de celulose microcristalina ou amorfa podem ser usados como portadores, ao passo que pós de sílica com tamanho de partícula muito fino podem ser usados como materiais de revestimento. Baseado na teoria de que os materiais portador e de revestimento podem reter apenas certas quantidades de líquido e ao mesmo tempo manter propriedades de fluxo e de compressão aceitáveis, um novo modelo matemático de formulação é provido para calcular as quantidades ótimas de materiais portador e de revestimento exigidos para produzir misturas de líquido/pó aceitavelmente fluentes e compressíveis.
