Abstract: A coating material for controlling drug release, useful for long acting formulations--e.g. for once-a-day administration, and to a long acting granular composition comprising a drug (especially one conventionally difficult to prepare in long acting form) coated with the coating material. This composition may be mixed with other granular drug formulations. The drug-release controlling coating material comprising, in a specific ration, one specific water-insoluble and low water-permeability polymers and two materials differing from each other in the pH-dependency of their solubility (pH-dependent polymer-materials).
Abstract: Described is an article for the controlled release and delivery to animal tissue of a pharmacologically active agent with or without an excipient and/or enhances which may be a causative factor in the occurrence of non-allergic or allergic contact dermatitis comprising an anti-dermatitis substance.

Abstract: The invention relates to a pharmaceutical composition in the form of a gelatin capsules consisting of a filling containing as active ingredient ranitidine or a physiologically acceptable salt thereof surrounded by a gelatin shell. The filling is formulated based on a non-aqueous matrix consisting of at least one fatty acid glyceride and/or mineral oil or paraffin. Preferably the matrix contains at least one surfactant. The matrix is essentially hydrophobic in character but is also sufficiently hydrophilic to permit dispersion and dissolution of the capsule filling in the gastrointenstinal tract.
Abstract: A sustained-release pharmaceutical preparation comprising an admixture of uncoated and/or single walled coated drug, and multi-units of microparticles of a multi-walled coated drug. The microparticle structure preferably has a core drug, an inner wall microencapsular enteric coating, such as a polymethyacrylic acid/acrylic acid copolymer or cellulose acetate phthalate, a solid acid such as citric acid, adipic acid, or an acidic ion exchange resin layered onto or included in the enteric layer, and an outer wall microencapsulated control coating, such as a polymethacrylic acid ester copolymer or ethyl cellulose. The multi-walled coated drug has a delayed, gradual, long-term release which takes place in the intestines while the uncoated and/or single walled coated drug has immediate therapeutic properties upon dissolution in the stomach. The enteric coating and control coating may be applied to core drug granules by a coacervation, spray coating or other process.
Abstract: A novel glycoside, 4.sup.G -alpha-D-glucopyranosyl rutin, is formed by a saccharide-transferring enzyme and glucoamylase in a solution which contains rutin together with glucoamylase. The 4.sup.G -alpha-D-glucopyranosyl rutin formed in such a solution is purified with a synthetic macroreticular resin, and crystallization in an organic solvent yields a complex crystal with the organic solvent. 4.sup.G -Alpha-D-glucopyranosyl rutin exhibits the same molecular absorption coefficient as intact rutin, and is readily water-soluble, substantially tasteless and odorless, and readily hydrolyzable in vivo to exhibit physiological activities inherent to rutin. These render 4.sup.G -alpha-D-glucopyranosyl rutin very useful as a highly-safe, natural yellow coloring agent, antioxidant, stabilizer, quality-improving agent, preventive, remedy, uv-absorbent and deterioration-preventing agent in foods, beverages, tobaccos, cigarets, feeds, pet foods, pharmaceuticals, cosmetics and plastics.
Abstract: Novel, linear, film-forming polymers and copolymers can be coated on certain metal surfaces, which polymers or copolymers are derived from one or more classes of ethylenically-unsaturated monomers and include at least one novel monomer having a bidentate chelating moiety. The polymers which contain bidentate chelating groups provide significant and varied chemical modification to a metal surface. When coated on a metal surface the polymers are useful as a protective coating or a priming layer.

Abstract: Controlled release microspheres of hydroxybutyrate polymer comprise active ingredient and hydroxybutyrate/hydrovalerate copolymer. The microspheres comprise a skin which is distinct from the general bulk of the microspheres, and this skin may have a porosity covering from 0-50% of the total surface area of the microsphere, this porosity being largely controlled by varying the hydroxyvalerate content of the polymer. The porosity of the interior of the microspheres can also be regulated. Control of the two porosities permits the attainment of a wide range of release rates for a wide range of active ingredients. The microspheres can be used in a wide variety of pharmaceutical, veterinary and agricultural applications.
