  Polymorphous forms of rifaximin, processes for their production and use thereof in medicinal preparations
  Patent 7,045,620
  Issued: May 16, 2006
  Inventor(s): Viscomi; Giuseppe C. & Campana; Manuela & Braga; Dario & Confortini; Donatella & Cannata; Vincenzo & Severini; Denis & Righi; Paolo & Rosini; Goffredo
  Assignee(s): Alfa Wassermann, S.p.A.
  Crystalline polymorphous forms of the rifaximin (INN) antibiotic named rifaximin α and rifaximin β, and a poorly crystalline form named rifaximin γ have been discovered. These forms are useful in the production of medicinal preparations for oral and topical use and can be obtained by means of a crystallization process carried out by hot-dissolving the raw rifaximin in ethyl alcohol and by causing the crystallization of the product by the addition of water at a determinate temperature and for a determinate period of time. The crystallization is followed by drying carried out under controlled conditions until a specific water content is reached in the end product.
