Abstract: The invention relates to a mucoadhesive medicinal preparation for administering active substances in veterinary or humane medicine, containing at least one active substance, which preparation is characterized in that it is a mucoadhesive matrix disintegratable in aqueous media, which matrix contains at least one matrix-forming polymer and wherein at least one active substance is dissolved or dispersed, and in that the said preparation disintegrates or erodes within maximally 15 minutes after introduction in an aqueous medium or in body fluids, or in that the preparation initially gels within maximally 15 min after its introduction in an aqueous medium or in body fluids, and disintegrates or erodes within maximally 30 min after said introduction.

Abstract: The invention relates to thin film-shaped or wafer-shaped pharmaceutical preparations for oral administration of active substances. The preparations contain at least one matrix-forming polymer which has at least one active substance and at least one carbon dioxide-forming substance dissolved or dispersed therein.

Abstract: The present invention relates to film-shaped administration forms for transmucosal administration of active substances to the human or animal body. The administration forms are characterized by an adaptation or approximation of the pH value of the base mass intended for the production of the administration form to the physiological pH value of the mucosa to which the administration form is to be applied, said base mass comprising a solvent or a mixture of solvents, at least one matrix-forming polymer and at least one active substance. The invention further comprises a process for the production of such preparations, and the use thereof as administration forms, particularly for pharmaceutical active substances, such that when the resultant administration forms are used, an irritation of the mucous membrane is reduced or even prevented.

Abstract: Process for the production, transport and storage of a therapeutic system which is in the form of a plaster and has an active layer supersaturated with active ingredient and containing the active ingredient in homogeneous dispersion or in solution, characterized in that it is carried out avoiding process parameters which favour or induce crystallization of active ingredient, and any type of pressure operating on the plaster and, in particular, on the active layer is avoided while it is carried out.

Abstract: An active substance-containing patch for the controlled release of nitroglycerin to the skin, consisting of an impermeable backing layer, a reservoir attached thereto and comprising pressure-sensitive hot melt adhesive and active substance, and a removable protective layer, in which patch the reservoir comprises in homogeneous mixture:a) tackifying soft and/or hard resins,b) plasticizers,c) nitroglycerin preparation.
