  • Patent number: 5993846
    Abstract: The invention relates to novel methods for making oil-in-water emulsions having mucoadhesive properties which are primarily intended for administration of biologically active compounds to mucosal surfaces. The emulsion has an aqueous continuous phase and a plurality of submicron particles having an average particle diameter of from 10 nm to 600 nm, with the particles having a hydrophobic phase of a fat or oil which forms a hydrophobic core that is surrounded by a surfactant layer. The emulsion further includes a mucoadhesive polymer which is a polymer or copolymer of acrylic acid or methacrylic acid, a poly (methyl vinyl ether/maleic anhydride) copolymer, pectin, alginic acid, hyaluronic acid, chitosan, gum tragacanth, karaya gum or carboxymethylcellulose surrounding the hydrophobic one. A biologically active compound may also be included, if desired.

  • Patent number: 5985249
    Abstract: Sticky dental compositions which include a sticky, glue-like matrix material for treating a variety of tooth or gum ailments, and methods for treating teeth using such compositions. For maximum comfort, an improved dental tray that is thin-walled, flexible and lightweight is used to hold the sticky dental composition adjacent the desired tooth surfaces. The sticky dental compositions include a sticky matrix material into which is dispersed an appropriate dental agent, such as a bleaching agent, a desensitizing agent, and an anticariogenic agent, an antimicrobial agent. The matrix material preferably includes carboxypolymethylene that has been partially neutralized with a base to reduce etching of the enamel. The carboxypolymethylene adds a unique stickiness to the dental composition which helps to adhere and retain the soft tray material against the person's teeth.

  • Patent number: 5980947
    Abstract: Formation of a drug into microspheres by an oil-on-water solvent evaporation process in which a mixed solvent of at least one water-insoluble solvent and at least one water-miscible solvent is used as a solvent of an oil phase. A fatty acid or a salt thereof or at least one glycerin fatty acid ester and/or at least one propylene glycol fatty acid ester are added to the mixed solvent. The oil phase may also comprise the mixed solvent; a fatty acid or a salt thereof; and at least one glycerin fatty acid ester and/or at least one propylene glycol fatty acid ester. This oil phase is mixed and emulsified with an aqueous phase to form an oil-in-water emulsion. The emulsion with a drug contained therein is then subjected to an oil-in water solvent evaporation to produce the microspheres. The resulting drug-containing microspheres contain the drug at a high concentration and slowly release from the initial stage after administration.

  • Patent number: 5976571
    Abstract: A drug delivery system (10) includes a first capsule half (12) having an inner chamber (16) for containing a drug (18) therein. A plug (28) is disposed in a passageway (26) of the capsule half (12) for plugging the opening (24) thereof. The plug (28) is releasable from the passageway opening (24) upon the application of pressure from within the inner chamber (16). A pump mechanism, reactive with the external environment of the capsule half (12), causes an increase in pressure within the inner chamber (16) and forces the plug (28) out of the passageway (26) to release the drug (18) from the inner chamber (16) and out of the passageway (26). Thusly, after initial release of drug from a second capsule half (14) releasably mounted on the first capsule half (12), the first capsule half (12) provides a second pulse of drug release at a predetermined time after initial ingestion of the capsule.
