Pharmaceutical compositions comprising polymorphic forms alpha, beta, and gamma of rifaximin |
| abstract |
Crystalline polymorphous forms of rifaximin (INN), referred to as rifaximin a and rifaximin 3, and a poorly crystalline form referred to as rifaximin γ, useful in the production of medicaments containing rifaximin for oral and topical use and 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 addition of water at a fixed temperature and for a fixed period of time, followed by a drying under controlled conditions until reaching a precise water content in the end product, are the object of the invention. |
