METHOD OF PRODUCING OF MICROCAPSULES OF TETRACYCLINE ANTIBIOTICS IN SODIUM ALGINATEMETHOD OF PRODUCING OF MICROCAPSULES OF AMINOGLYCOSIDE ANTIBIOTICS IN SODIUM ALGINATE Russian patent published in 2017 - IPC A61K31/65 A61K47/36 A61K9/51 A61J3/07 B82B3/00

Abstract RU 2611367 C1

FIELD: nanotechnology.

SUBSTANCE: an antibiotic powder is added to sodium alginate suspension in petroleum ether and 0.01 g of E472s drug as a surface-active substance, then, 5 ml of carbon tetrachloride is added, the obtained suspension is filtered and dried. The mass ratio core:shell in nanocapsules is 1:3 or 1:1.

EFFECT: nanocapsules of antibiotics manufacture process simplification and acceleration and weight yield increase.
