Disclosed is a drug delivery system from which a macrocyclic lactone can be released with a desirable zero order release profile. The system is based on the use of thermoplastic polymers, and particularly of polyethylene vinyl acetate copolymers (EVA). The drug delivery system of the invention comprises a solid non-porous reservoir in which the macrocyclic lactone is contained, preferably in a concentration well above the saturation concentration, and a non-porous skin covering the reservoir not initially loaded with the drug. The system is preferably in the form of a rod, wherein the core and the skin are concentric, and the end surfaces of the rod are not skin-covered.

Macrocyclic lactone drug delivery system

The present invention relates to a veterinary zoo-technical drug delivery system (device) for the simultaneous release of two or more active substances, which system releases the active substances in a substantially constant ratio over a prolonged period of time. The drug delivery system can be in different forms, such as e.g. an implant, or a intravaginal device such as a helical coil, a spring or a ring.

The subject invention provides a drug delivery system comprising at least one compartment comprising (i) a drug-loaded thermoplastic polymer core layer, (ii) a drug-loaded thermoplastic polymer intermediate layer and (iii) a non-medicated thermoplastic polymer skin covering the intermediate layer, wherein said core layer is loaded with crystals of a first (pharmaceutically) active compound and said intermediate layer is loaded with, crystals of the second (pharmaceutically) active compound.

The subject invention provides an X-ray visible drug delivery device for subdermal administration of a contraceptive or hormone replacement therapy.

X-ray visible drug delivery device

An intrauterine system is disclosed for use in the treatment of dysfunctional uterine bleeding; menorraghia; dysmenorrhoea; endometriosis; uterine fibroids; climacteric complaints; osteoporosis; and urogenital atrophy. The system is formed by a frame defining an interior space for receipt of a deposit of a therapeutically effective dose of a biologically active compound. The frame has an open structure allowing access to a substantial part of an outer surface of the deposit, and the deposit has a rate controlling structure that controls a rate of release of the compound within the uterus. One or more retention elements are provided on the frame for retaining the frame within the uterus of a female mammal.
