FIELD: chemistry.

SUBSTANCE: invention provides a method of encapsulating a medicinal preparation via nonsolvent deposition, characterised by that the core of the microcapsules used is fenbendazole, which is pre-dissolved in dioxane or dimethylsulphoxide, the envelope used is sodium carboxymethyl cellulose which is deposited from a solution in carbinol by adding, as the nonsolvent, isopropanol and water at 25°C.

EFFECT: simple and faster process of producing microcapsules, reduced losses when producing microcapsules, high mass output.
