FIELD: medicine.
SUBSTANCE: invention relates to composition for peroral introduction, which possesses properties of modified release. According to invention composition includes pharmaceutically acceptable excipients and complex medication-ion-exchanging resin with coating with modified release, which contains pharmaceutically active medication, combined with pharmaceutically acceptable ion-exchanging resin. Complex has solidified barrier coating with high rupture strength, water-permeable, water-insoluble, which contains polyvinyl acetate polymer, stabiliser and efficient amount of plastifier. Said coating is in fact non-sticky, when applied onto complex in absence of anti-adhesive preparation, if composition presents tablet, complex medication-ion-exchanging resin with coating additionally contains release-retarding substance in matrix together with complex medication-ion-exchanging resin. Invention also relates to product with modified release, including package which contains composition described above.
EFFECT: invention ensures regulated prolonged active agent release without breaking coating integrity, without application of water-soluble impregnating substances and without agglomeration of complex particles during application of coating.
