Abstract

"FORMAS POLIMóRFICAS DE RIFAXIMIN, PROCESSOS PARA SUA PRODUçãO E SEU USO EM PREPARAçõES MEDICINAIS". A presente invenção refere-se a formas polimórficas cristalinas de rifaximin (INN), referidas como rifaximin alfa e rifaximin beta, e a uma forma pobremente cristalina referida como rifaximin gama, úteis na produção de medicamentos contendo rifaximin para o uso oral e tópico e obtidas por meio de um processo de cristalização realizado por dissolução quente de rifaximin bruto em álcool etílico e causando a cristalização do produto pela adição de água em uma temperatura fixada e por um período de tempo fixado, seguido por secagem sob condições controladas até atingir um preciso teor de água no produto final, são os objetos da invenção.
