INHALATION COMPOSITIONS CONTAINING GLYCOPYRRONIUM SALTS

摘要

FIELD: medicine. ^ SUBSTANCE: declared invention refers to chemical-pharmaceutical industry, and concerns a method for making dry powder glycopyrronium salt inhalation compositions characterised by high stability. The method involves (a) finish grinding of glycopyrronium salt together with an anti-adhesive agent and (b) mixing with carrier particles with making a dry powder composition where the carrier particles are mixed with the fine mixture of glycopyrronium salt and the anti-adhesive agent at the mass ratio varying within 200:1 to 20:1. ^ EFFECT: prepared inhalation compositions possess high storage stability. ^ 13 cl, 2 ex, 1 tbl
