METHODS FOR PREPARING TRANSDERMAL THERAPEUTIC SYSTEMS BASED ON POLY(LACTIC-CO-GLYCOLIC ACID) (VERSIONS)

摘要

FIELD: medicine, pharmaceutics.;SUBSTANCE: invention refers to medicine. What is described is a method for preparing a transdermal therapeutic system based on poly(lactic-co-glycolic acid) involving dissolving poly lactide-co-glycolide and a pharmaceutically active substance in an organic solvent, mixing the prepared solution until dissolved completely, hot air drying until dry completely and having a constant weight to prepare a film, cutting the film into sections and packing, with the relation of lactide and glycolide varying within the range of 95:5 to 5:95 (versions).;EFFECT: preparing the transdermal therapeutic system based on poly(lactic-co-glycolic acid) that is biodegradable.;33 cl, 1 dwg, 3 tbl, 6 ex
