METHOD FOR PRODUCING ASPIRIN NANOCAPSULES IN SODIUM ALGINATE Russian patent published in 2015 - IPC A61K31/616 A61K9/50 B82B1/00 B01J13/06

Abstract RU 2565396 C1

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to chemical-pharmaceutical industry and represents a method for drug encapsulation by non-solvent addition,differing by the fact that a nanocapsule core is aspirin, and a coating is sodium alginate deposited from butanol suspension by adding carbon tetrachloride as a non-solvent and water that is followed by drying at room temperature.

EFFECT: invention provides simplifying and accelerating the nanoencapsulation process, reducing accompanying loss (higher weight yield).
