METHOD OF BIOENCAPSULATION Russian patent published in 2015 - IPC A61K31/155 A61K47/42 A61K9/64 A61J3/07 B01J13/02 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention relates to field of encapsulation, in particular to method of obtaining microcapsules Biopag-D in envelope of human leukocytic interferon (β- or α-interferon). According to invention method, suspension of Biopag-D in water is added to 1-% water solution of interferon in presence of medication E472c and mixed to transparent solution. Suspension of Biopag-D and interferon solution are taken in weight ratio 3:1 or 2.5:1. Butanol, and then acetone taken in ratio 1:5% vol/vol 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 ensures simplification and acceleration of process of obtaining microcapsules, reduction of loss in the process of their obtaining (increase of output by weight).
