Abstract

Способ получения нанокапсул умифеновира (Арбидола) в альгинате натрия, характеризующийся тем, что в качестве оболочки нанокапсул используется альгинат натрия, а в качестве ядра - умифеновир при получении нанокапсул методом осаждения нерастворителем с применением петролейного эфира в качестве осадителя.A method of producing nanocapsules of umifenovir (Arbidol) in sodium alginate, characterized in that sodium alginate is used as the shell of the nanocapsules, and umifenovir is used as the core when nanocapsules are prepared by the non-solvent precipitation method using petroleum ether as a precipitant.
