FIELD: medicine.
SUBSTANCE: the [present innovation deals with manufacturing intestinally soluble capsular forms of medicinal preparations, particularly, to the technology for creating capsular membranes of improved protective properties. The innovation deals with the method for obtaining capsular membrane out of calcium alginate due to successive keeping capsular nuclei in solutions of sodium alginate and calcium chloride, in which sodium alginate solution at concentration of 1.5-2.0% (weight/volume) should be pre-treated with ultrasound for about 8-10 at the power of 400-450 W/sq. cm. Calcium chloride solution should be applied at concentration of 2.0-2.5%, moreover, the terms for keeping capsular nuclei in solutions of sodium alginate and calcium chloride corresponds to 5 min in every solution.
EFFECT: higher efficiency.
