Abstract
Patente de Invenção: <B>"FORMULAçãO DE LIBERAçãO PROLONGADA"<D>. Esta invenção refere-se a uma formulação de dosagem de liberação prolongada por 24 horas e a sua forma de dosagem unitária para cloridrato de venlafaxina, um antidepressivo, que proporciona um controle dos níveis plasmáticos sang³íneos melhor do que as formulações de comprimidos convencionais, que têm de ser administradas duas ou mais vezes ao dia, e também proporciona uma incidência de náusea e vómitos menor do que comprimidos convencionais. Em seu aspecto principal, esta invenção apresenta um núcleo aperfeiçoado de esferóides de liberação prolongada, composto por cloridrato de venlafaxina e celulose microcristalina, isto é, sem a adição de hidroxipropilmetil celulose.
