Abstract: A device for producing a patch which includes a plurality of microstructures has at least one die. The die is used to produce a microstructure and has a plurality of depressions for this purpose. Additionally, a support layer, which is provided with an adhesive layer, is provided. In a preferred embodiment, it is possible to move the microstructure formed in the die in the direction of the support layer using a lifting device such that said microstructure adheres to the face of the support layer, which is provided with the adhesive layer. For example, by carrying out a corresponding method multiple times, multiple microstructures can be provided on the support layer adjacently to one another. Optionally, multiple dies can also be provided so that multiple microstructures can be simultaneously arranged on the support layer.

Abstract: An apparatus for producing microarrays includes a die. A plurality of cavities is formed in the die. A cover element is additionally provided in order to cover regions between the cavities. In this manner it is possible to remove an active agent-containing liquid from the regions formed between the cavities when metering said liquid. This is achieved in that the cover element is removed again. An active agent-free liquid can then be metered, with which a remaining portion of the cavities are filled, and a support layer is formed on the upper surface of the die.

Abstract: Topical pharmaceutical compositions are described comprising: (a) bexarotene; (b) a corticosteroid; and (c) a carrier or vehicle. Said compositions are useful for the treatment of skin disorders.
