  • Polymeric Drug-Delivery Material, Method for Manufacturing Thereof and Method for Delivery of a Drug-Delivery Composition
    Publication number: 20170095419
    Abstract: A method for manufacturing a drug-delivery composition includes providing at least one pharmaceutically active compound, a dry powder comprising at least a polymer, and an aqueous solution. The dry powder, the pharmaceutically active compound and the aqueous solution are mixed to form a paste-like or semi-solid drug-delivery composition, wherein the aqueous solution is added in an amount of less than or equal to twice the total dry mass of the dry powder.
    Type: Application
    Filed: September 27, 2016
    Publication date: April 6, 2017
    Inventors: Andreas Voigt, Jörg Kriwanek, Scott Hampton, Andreas Reiff, Sonja Ludwig
