Method for the low-waste manufacture of diskoid moulded bodies containing active ingredients, and transdermal therapeutic systems containing same

Abstract From the Canadian patent

The invention relates to laminate bodies or disks containing active ingredients, which are especially suitable as active ingredient reservoirs for transdermal therapeutic systems and are obtained on the basis of an oblong moulded shape whose outer surface area corresponds to the contours of the laminate bodies to be manufactured and whose cross-sectional structure corresponds to the structure of the laminate bodies by slicing off sections , at right angle to the lengthways direction of the oblong moulded body. In the simplest case, the moulded body consists of a homogeneous mass of active ingredient and has the form of a full cylinder which is sliced perpendicular , to its axis at …
