  • Publication number: 20200368357
    Abstract: The present invention relates to process for preparing a drug delivery composition comprising the steps of a) preparing a masterbatch comprising a drug and a first polymer by (i) extruding the first polymer, wherein said first polymer has a melting temperature below 140° C.; and (ii) introducing the drug during extrusion of the first polymer, with a drug content between 0.1% and 90%, based on the total weight of the masterbatch; and b) introducing the masterbatch in a polymer-based matrix during production of the drug delivery composition, wherein step a) is performed at a temperature at which the first polymer is in a partially or totally molten state, and step b) is performed at a temperature at which both the first polymer and at least a polymer of the polymer-based matrix are in a partially or totally molten state.
