Abstract: A novel granular drug delivery system having a gel-forming dietary fiber that can be made into a an orally-ingestible dispersion by admixture with a liquid that can deliver an effective dose of a pharmaceutically-active compound. The granular drug delivery system comprises granules consisting essentially of a pharmaceutically active compound, and a gel-forming dietary fiber, the granules being coated with at least one of the following: a gel-forming dietary fiber, a starch or a protein. The composition may further include a mineral salt that releases a physiologically-acceptable gas upon ingestion. The composition of the granular drug delivery system will deliver microgram quantities of a pharmaceutically-active compound in an orally-ingestible dispersion without forming a thick gel and without forming "hot" and "cold" spots of the pharmaceutically-active compound.
Abstract: A material for tissue separation at healing processes in injured soft tissue in mammals including man is described. The material consists of a porous flexible sheet of a protein-free bioresorbable polymer. Processes for preparation of the material and use thereof are also described.

Abstract: Absorbent products, especially catamenial tampons, for absorbing body fluids, such as menstrual fluid, blood and wound exudates, comprise an amount of a compound effective to inhibit the production of toxic shock syndrome toxin-1 by Staphylococcus aureus bacteria when the products are brought into contact with the bacteria. The compound is selected from the group consisting of monoesters of a polyhydric aliphatic alcohol and a C.sub.8 -C.sub.18 fatty acid; diesters of a polyhydric aliphatic alcohol and a C.sub.8 -C.sub.18 fatty acid; and mixtures thereof. The monoesters and diesters have at least one hydroxyl group associated with their aliphatic alcohol residue.
Abstract: Various embodiments of a delivery system for the effective and efficient administration of low viscosity cosmetic and dermatological ingredients without the use of plasters or repetitive applications that are currently necessary. The claimed embodiments eliminate migration of the low viscosity application liquid to areas where treatment is not required and/or sensitive areas of the patient's body which could be adversely affected if contacted by the application liquid.
Abstract: The present invention is concerned with improving the delivery of a drug from a ruminal delivery device to give a consistent delivery of drug to the ruminal environment. Thus, the invention is directed to an improved ruminal drug delivery device comprising a semipermeable membrane having an exit orifice and defining a compartment, the compartment containing a swellable osmotic agent expandable driving member, a drug to be dispensed, a density element and, optionally, a partition layer between the osmotic expandable driving member and the drug formulation, wherein the improvement comprises an essentially gas-impermeable barrier means that separates the density element from the other components within the delivery device for isolating gases evolved from the density element from the other components within the delivery device. The barrier means further includes a coupling to transfer osmotic pressure to the semipermeable wall.

Abstract: The applicants have discovered that by simultaneously administering particular combinations of drugs at particular dosage levels by means of a transdermal delivery system, anesthesia may be induced in patients requiring such treatment. It has been found that profound sedation or an analgesic effect may be produced by means of a particular combination of pharmacologic agents which are administered simultaneously by transdermal administration. A patch system has been devised which is useful for reversing anesthesia.

Abstract: Disclosed is the feed or feed additive granular agent containing a phisiologically active substance and a coating layer having a laminar structure in which the tabular crystals are arranged in a laminated state. The coating layer comprises (a) one or more substances selected from the group consisting of a specific fatty acid or ester thereof, a specific animal or vegetable fat and fatty oil which may be hardened by hydrogenation, and a specific wax, and (b) tabular crystals of a substance which is sparingly water-soluble under a neutral condition but is readily water-soluble under an acidic condition and which has an average particle size of 5 to 30 .mu.m, wherein said coating layer is present in a coating ratio of 5% by weight or more and 50% by weight or less, wherein said first coating material and said second coating material are in a proportion of 3:2 to 1:3 by weight, and process for producing the same.
Abstract: A device for the transdermal administration of a drug comprising a microporous tie layer located between the drug reservoir and the contact adhesive. The tie layer eliminates blooming and delamination and has no appreciable adverse effect on either the drug flux or release rate from the device.
Abstract: A method and apparatus for manufacturing a wound dressing, and a wound dressing produced thereby. The upper surface of a perforated carrier material (2) is coated with a curable silicone mixture (3) and cold air is blown onto the underside of the coated carrier material. Heat is then applied to the silicone mixture until it has cured to a silicone gel.
Abstract: The invention concerns pastilles made from completely or partly water-soluble, natural and/or synthetic polymers selected from the group comprising gums, alginates, carrageen, starch, pectin and gelatin and containing polydimethylsiloxanes (dimeticon, simethicone). The invention also concerns a method of producing such pastilles.
Abstract: A method of administering nicotine transdermally in which a nicotine patch, capable of administering nicotine for at least 16 hours at rates that are efficacious in smoking cessation therapy, is applied in the morning upon waking and removed prior to sleep. This method is effective even though nicotine is not essential during sleep and many smokers experience morning craving.

Abstract: An adhesive dressing suitable for moist wounds includes a first layer comprising a substrate having a layer of pressure sensitive adhesive on a wound facing surface and a second layer comprising a moisture vapour permeable continuous film. The second layer is attached to the non wound facing surface of the first layer at spaced apart intervals thereby to form a plurality of discrete cellular voids between said first and second layers. The first layer has apertures therein to allow passage of liquids therethrough into the cellular voids and total area of the dressing defined by the cellular voids is from 20% to 80% of the total operable area of the dressing.
