Abstract: The invention relates to an oral multiparticle pharmaceutical dosage form in the form of a receptacle reducing the pH values of stomach, containing a plurality of pellets, particles, granules or agglomerates whose mean diameter ranges from 50 to 2500 ?n substentially consisting of a) an internal matrix layer containing an active agent which is neither peptide or protein, nor the derivatives or conjugates thereof, a lipophilic matrix whose melting point is greater than 37° C. and a polymer with mucoadhesive effect, b) an external film coating substentially consisting of a polymer or an anionic copolymer which is optionally formulated with conventional pharmaceutical additives, wherein the active agent has a water solubility according to DAB 10, of at least 30 volume parts of water for one part by weight of the active agent and is coated with the lipophilic matrix and said active agent-containing lipophilic matrix is coated with a matrix made of a polymer with mucoadhesive effect.

Abstract: A filter arrangement, for cleaning gases contaminated with particles, has at least one filter unit with an exterior and an interior filter (3.1, 3.2), wherein the exterior and interior filters can be moved relative to each other, thereby exposing an opening (3.4) in the bottom regions thereof. This allows cleaning of filter units at the site of the filter units without disassembly of the same (cleaning in place—CIP). A method for cleaning is provided in that the region of the filter unit on the clean gas side including introducing a fluid sprayed via a cleaning lance protruding into the clean gas region while exposing a gap (3.4) in the bottom region of the exterior and interior filters.
