- 摘要:
- A polymorphic mixture of α / β form of rifaximin in a relative proportion of 85/15 ± 3 characterized by an X-ray spectrum with characteristic 2theta values at (relative intensity): 5.32 (11%), 5.78 ( 19%), 6.50 (27%), 7.24 (45%), 7.82 (61%), 8.80 (100%), 10.50 (59%), 11.02 (35% ), 11.58 (32%), 13.08 (20%), 14.42 (26%), 17.32 (48%), 17.68 (93%), 18.58 (79%), 19.52 (61%), 21.04 (52%), 21.60 (30%), 21.92 (46%).Una mezcla polimórfica de forma α/ß de rifaximina en una proporción relativa de 85/15 ± 3 caracterizada por un espectro de rayos X con valores de 2theta característicos a (intensidad relativa): 5,32 (11 %), 5,78 (19 %), 6,50 (27 %), 7,24 (45 %), 7,82 (61 %), 8,80 (100 %), 10,50 (59 %), 11,02 (35 %), 11,58 (32 %), 13,08 (20 %), 14,42 (26 %), 17,32 (48 %), 17,68 (93 %), 18,58 (79 %), 19,52 (61 %), 21,04 (52 %), 21,60 (30 %), 21,92 (46 %).
