BIO-COMPATIBLE NANO AND MICROPARTICLES COATED WITH STABILIZERS FOR PULMONARY APPLICATION

摘要

The present invention provides stabilizers for the coating of biocompatible nano- and microparticles which prevent aggregation of the particles during preparation, storage as well as before and after nebulization and which are suitable to be utilized for the manufacture of a pharmaceutical preparation for pulmonary application. Biocompatible nano- and microparticles of this invention have a stabilizer layer thickness ranging from 1 to 200 nm and contain an active substance. Said biocompatible nano- and microparticles of this invention can be synthesized for example using the emulsion method known to the expert with subsequent coating by mixing of uncoated particles with the stabilizer, by chemical vapor deposition, by spraying or by covalent attachment.
