DRUG DELIVERY SYSTEM
Abstract: the present invention relates to a drug delivery system () comprising a core () made of a first polymeric material () and comprising a first active ingredient (), and a sheath () made of a second polymeric material () and comprising a second active ingredient () dispersed and/or incorporated in the second polymeric material in a concentration of above 10 wt % based on the weight of the sheath (), and below the percolation threshold of said second active ingredient in the sheath (). using the drug delivery system according to the present the inventors have found that it is possible to attain independent and optimal release of two active ingredients without the need for complex assembly of parts and without the need to use sophisticated multi-layer extrusion technology.
Inventor(s): Wouter de Graaff, Hans Van Laarhoven
CPC Classification: A61K9/0036 (Medicinal preparations characterised by special physical form {(nuclear magnetic resonance contrast preparations or magnetic resonance imaging contrast preparations ; preparations containing radioactive substances )})
