Abstract

"PROCESSOS PAPA GRANULAR áCIDO POLIACRìLICO, PARA FORNECER áCIDO POLIACRìLICO PARA APLICAçõES DE LIBERAçãO CONTROLADA E PARA FABRICAR UM TABLETE DE LIBERAçãO CONTROLADA, E, PRODUTO DE áCIDO POLIACRìLICO". A presente invenção diz respeito a um processo para formação de grânulos de ácido poliacrílico e grânulos formados destes em que os grânulos são fluíveis, têm uma densidade aparente aumentada relativo aos ácidos poliacrílicos polimerizados, e uma quantidade baixa de resíduo que é no geral aqui caracterizado como partículas que passam através de uma peneira reticulada 325. Os grânulos formados pelo processo da presente invenção podem ser usados para preparar os tabletes de liberação controlada, especialmente tabletes farmacêuticos de liberação controlada. As propriedades de liberação controlada dos tabletes formados dos grânulos preparados de acordo com a presente invenção são inesperadamente melhores do que os tabletes preparados dos grânulos formados por outros processos de granulação conhecidos.
