METHOD OF SUBLIMATION DEHYDRATION OF HIGH-DISPERSE BIOLOGICALLY ACTIVE MATERIALS Russian patent published in 2012 - IPC A61K9/66 A61K35/74 A61K49/16 A61K47/04 F26B5/16

Abstract RU 2440106 C2

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to pharmaceutical industry and represents a method of sublimation dehydration of high-disperse biologically active materials found in a microdrop state characterised by the fact that the microdrop powder is frozen at temperature -35°C to -45°C for 1.5 to 8 h, and then dehydrated.

EFFECT: invention provides reduced duration of the dehydration process of biologically active materials.
