Abstract

Inventia se refera la formele polimorfe de rifaximina, si anume la formele Delta si Epsilon.Forma polimorfa de rifaximina Delta este caracterizata printr-un continut de apa de la 2,5% pana la 6,0%, de preferinta de la 3,0% pana la 4,5%, si o difractograma pe pulbere cu raze X avand varfuri la valorile unghiurilor de difractie 2Theta 5,7°±0,2, 6,7°±0,2, 7,1°±0,2, 8,0°±0,2, 8,7°±0,2, 10,4°±0,2, 10,8°±0,2, 11,3°±0,2, 12,1°±0,2, 17,0°±0,2, 17,3°±0,2, 17,5°±0,2, 18,5°±0,2, 18,8°±0,2, 19,1°±0,2, 21,0°±0,2, 21,5°±0,2.Forma polimorfa de rifaximina Epsilon.este caracterizata printr-o difractograma pe pulbere cu raze X avand varfuri la valorile unghiurilor de difractie 2Theta 7,0°±0,2, 7,3°±0,2, 8,2°±0,2, 8,7°±0,2, 10,3°±0,2, 11,1°±0,2, 11,7°±0,2, 12,4°±0,2, 14,5°±0,2, 16,3°±0,2, 17,2°±0,2, 18,0°±0,2, 19,4°±0,2.Inventia se refera de asemenea la procedee de obtinere a formelor polimorfe de rifaximina Delta si Epsilon. printr-un proces de cristalizare desfasurat prin diluarea rifaximinei brute in alcool etilic si precipitarea prin adaugarea apei la o anumita temperatura si intr-o perioada prestabilita de timp cu uscarea ulterioara in conditii de vid sau la o presiune atmosferica normala pana la atingerea unui continut anumit de apa in produsul finit. Formele polimorfe de rifaximina obtinute pot fi utilizate in calitate de preparate medicamentoase cu actiune antibiotica pentru administrare orala si topica.
