Abstract

Crystalline polymorphous forms of rifaximin (INN) antibiotic named rifaximin alpha and rifaximin beta, and a poorly crystalline form named rifaximin gamma, useful in the production of medicinal preparations containing rifaximin for oral and topical use and obtained by means of a crystallization 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 determinate temperature and for a determinate period of time, followed by a drying carried out under controlled conditions until reaching a settled water content in the end product, are the object of the invention.

Abstract

The present invention relates to rifaximin polymorphic forms a, b and g, the processes for their prepn. and the use thereof in the manuf. of medicinal prepns. for the oral or topical route. A hydroalcoholic suspension of 5 g of rifaximin g was heated at 40 Deg for 24 h, the suspension was then filtered and the solid was washed with water, then dried under vacuum at room temp. until const. wt. 4 g of rifaximin was obtained, showing a powder X-ray diffractogram corresponding to that of the polymorphic form a and a water content equal to 2.6%.
