Abstract

Invenţia se referă la formele polimorfe de rifaximină, şi anume la formele δ şi ε.Forma polimorfă de rifaximină δ este caracterizată printr-un conţinut de apă de la 2,5% până la 6,0%, de preferinţă de la 3,0% până la 4,5%, şi o difractogramă pe pulbere cu raze X având vârfuri la valorile unghiurilor de difracţie 2Θ 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 polimorfă de rifaximină ε este caracterizată printr-o difractogramă pe pulbere cu raze X având vârfuri la valorile unghiurilor de difracţie 2Θ 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.Invenţia se referă de asemenea la procedee de obţinere a formelor polimorfe de rifaximină δ şi ε printr-un proces de cristalizare desfăşurat prin diluarea rifaximinei brute în alcool etilic şi precipitarea prin adăugarea apei la o anumită temperatură şi într-o perioadă prestabilită de timp cu uscarea ulterioară în condiţii de vid sau la o presiune atmosferică normală până la atingerea unui conţinut anumit de apă în produsul finit.Formele polimorfe de rifaximină obţinute pot fi utilizate în calitate de preparate medicamentoase cu acţiune antibiotică pentru administrare orală şi topică.
