FIELD: pharmaceutical industry.
SUBSTANCE: invention relates to the pharmaceutical industry, in particular to a process for the preparation of phenibut microcapsules in sodium alginate, comprising obtaining a homogeneous suspension of phenibut in 1–2 % aqueous solution of sodium alginate, then adding the resulting suspension dropwise in 2 % solution of calcium chloride, which leads to gel formation and the production of mentioned microcapsules.
EFFECT: invention provides a control of the release rate of phenibut from the microcapsules.
