METHOD OF BIOENCAPSULATION Russian patent published in 2015 - IPC A61K31/545 A61K9/50 A61K47/42 A61J3/07 B01J13/02 

FIELD: chemistry.

SUBSTANCE: invention relates to field of encapsulation, in particular to method of obtaining microcapsules of medications from cephalosporin group in human leukocyte interferon (β- or α-interferon) coat. In accordance to invention cephalosporin powder and E472c preparation are added to 1% water solution of human leukocyte interferon in α- or β-form and mixed until reaction mixture components dissolve. After formation of transparent solution butanol and acetone are added. Obtained suspension of microcapsules is filtered, washed and dried. Process of obtaining microcapsules is realised at 25°C for 15 min.

EFFECT: invention provides simplification and acceleration of process of obtaining microcapsules, reduction of loss in the process of their obtaining (increase of output by weight).
