FIELD: medicine, pharmaceutics.SUBSTANCE: present invention refers to L-glucose monohydrate used for colon cleansing, to a method for preparing it, to compositions containing above monohydrate, to a method of colon cleansing and to a kit for colon cleansing. Generally, presented L-glucose monohydrate has an X-ray powder diffraction (XRPD) pattern containing one or more characteristic peaks at 9.24, 18.46, 19.78, 20.24 and 28.36±0.2 degrees 2?, optical rotation from -52.5 to -53.3 degrees calculated with reference to anhydrous L-glucose, and purity of at least 99%. The method for preparing L-glucose monohydrate involves (a) adding L-glucose to water and heating at low pressure, and (b) cooling the prepared solution to form L-glucose monohydrate.EFFECT: preparing the colon cleansing composition.22 cl, 1 dwg, 2 tbl, 33 ex |
