Abstract

FORMAS POLIMORFAS DE RIFAXIMINA, PROCESSOS PARA SUA PRODUçãO E USO DAS MESMAS EM COMPOSIçõES MEDICINAIS. A presente invenção refere-se a formas polimórficas cristalinas do antibiótico rifaximina (INN), denominadas de rifaximina <sym> e rifaximina <sym>, de utilidade na produção de composições medicinais contendo rifaximina para uso tópico e oral, obtidas através de um processo de cristalização efetivado mediante dissolução a quente da rifaximina bruta em álcool etílico, provocando a cristalização do produto através da adição de água a uma determinada temperatura e por um determinado período de tempo, seguido de secagem efetuada sob condições controladas, até se alcançar um teor de água estabelecido para o produto final.
