titleOfInvention |
Method for producing a drug delivery system on the basis of polyelectrolyte complexes |
abstract |
The invention relates to the fields of polymer chemistry, pharmacy and medicine and relates to a method by which for example medicaments as implant components are released in the environment of the implant. The aim of the invention is to provide a method which in a simple and easily reproducible manner produces a drug delivery system which releases medicaments in a locally targeted and controllably delayed manner. The aim is achieved by a method in which polyanions and polycations are mixed in a liquid in a non-stöchiometric ratio, based on the charged monomer units, wherein medicaments are added either before, during or after the mixing of the polyelectrolytes, or charge-carrying medicaments and an oppositely charged polyelectrolyte are mixed, and after mixing the resulting polyelectrolyte complex is applied to the surface of a medicinal agent or is positioned on the surface directly at the site where the medicament is to be released. |
