Title: INTRAVAGINAL DRUG DELIVERY SYSTEM, METHOD FOR MANUFACTURING SUCH SYSTEM AND ITS USE IN GYNECOLOGICAL THERAPIES AND CONTRACEPTION
Abstract:
The invention relates to an intravaginal ring consisting of an inert carrier material (A) embedding at least on drug containing insert, wherein the insert(s) are made of a biocompatible polymer material (B) which is enclosed with a cylinder wall (sleeve) made of an inert material impermeable to the drag to reduce the amount of unused drag substance at the end of the wearing period and thus reducing the environmental burden when the IVR is disposed.
