Glyceride Patents (Class 514/786)
  • Patent number: 5582837
    Abstract: Sustained release oral drug dosage forms that comprise a tablet or capsule containing a plurality of particles of a solid-state drug dispersed in alkyl cellulose such as hydroxyethylcellulose or hydroxypropylcellulose. Once ingested the tablet or capsule disintegrates to disperse the particles into the stomach where they imbibe water to cause them to swell and also to become slippery, thus enhancing their retention in the stomach. Imbibed water from the gastric fluid dissolves the drug entrapped in the particles and the resulting solution diffuses from the dispersed particles, assuring that no solid drug, which with some drugs is more irritating, contacts the mucosal tissue. A number of embodiments of the dosage form utilizing different drugs are exemplified and the benefits are explained. Aspirin is one example.

  • Patent number: 5244925
    Abstract: The invention relates to emulsions intended for parenteral administration and contaning a hydrophobic phase emulsified in a an aqueous phase. In accordance with the invention, a substantial part of the hydrophobic phase contains one or more alkyl esters of pharmacologically acceptable fatty acids, and particularly their ethyl esters. The emulsions can be used for parenteral nutrient supply and as vehicles for pharmacologically active substances or agents and may also be used for both purposes in combination.

  • Patent number: 5230895
    Abstract: An in vivo method is described for treating a subject for periodontal disease by placing a mixture of a glyceride composition and a therapeutic agent in the periodontal pocket of subject such that the therapeutic agent is released in a sustained manner. The glyceride composition is selected such that the mixture of the glyceride composition and the therapeutic agent is capable of forming a gel in the environment of the periodontal pocket. Also described is a sustained release delivery system comprising the mixture of the glyceride composition and therapeutic agent.

  • Patent number: 5221286
    Abstract: This invention relates to a nonionic cold mix emulsion and preparation thereof. More particularly, the present invention relates to a cosmetic composition in the form of a cream preparation which comprises a discontinuous phase dispersed in a continuous phase. The continuous phase contains water, an emulsifier, and at least one oxidizing agent. The discontinuous phase contains salts of fatty acid esters of lactylic acid, saturated monoglycerides and propylene glycol monoesters. The emulsions are particularly suitable as components of oxidizing preparations for the bleaching of hair and for the dying of hair with oxidation hair dyes and hair bleaches.

  • Patent number: 5215758
    Abstract: The controlled release of therapeutically active agents is achieved from a controlled release matrix of sodium alginate and a calcium salt. When the composition is to be administered rectally, the matrix is combined with a therapeutically active agent and a suitable suppository base. When the composition is to be administered orally, the matrix further includes a higher aliphatic alcohol.

  • Patent number: 5208031
    Abstract: This invention relates to the use of zinc salts as anti-viral agents in sexual lubricants. A zinc salt which releases divalent zinc ions in an aqueous carrier fluid is provided in a sexual lubricant formulation which is spread on the genitals before sexual intercourse. The mixture is non-irritating, and the zinc ions serve as an anti-viral agent to reduce the risk of contracting genital herpes if a sexual partner is infected. These lubricants may also reduce the risk of infection by other sexually transmitted viral diseases, such as hepatitis, papilloma viruses, and AIDS. A preferred lubricant formulation comprises water, a thickening or suspending agent, a lubricating agent, and a suitable zinc salt. Salts which have been tested and shown to be non-irritating during sexual intercourse include zinc acetate, zinc propionate, and zinc gluconate. Other zinc salts have also been identified which are soluble in water and have low pK values, which indicates a high rate of zinc ion release.
