  • Patent number: 10280177
    Abstract: Polyols stabilize polymorphous form of rifaximin, in particular the ? form. When polyols having at least two hydroxy groups are added to rifaximin powder, polymorph ? is stable and remains stable in time independently from the environment humidity. In this invention a method to prepare formulations constituted by pure and stable polymorphous forms able to give a pharmaceutical product is described.
