  • Patent number: 6193985
    Abstract: The present invention provides the use of a tocopherol or a derivative thereof as a solvent and/or emulsifier for substantially insoluble and sparingly soluble biologically active agents, especially in the manufacture of pharmaceutical compositions. Such compositions are particularly suitable for transmucosal, and especially intranasal or rectal administration, or administration via the oral cavity.

  • Patent number: 5433352
    Abstract: A liquid dispensing device which includes a housing and a spring actuated lever arm hingedly connected to the housing and having a latch operatively connected to a toothed bar wherein upon depression of the lever arm the toothed bar is axially displaced toward the front end of the housing and during return of the lever arm to its original position, the toothed bar is released, wherein the lever arm, the spring and the latch are integral, and the spring and latch are the same element.

  • Patent number: 5143934
    Abstract: Controlled delivery of biologically active agents such as pharmaceuticals to body sites is accomplished by combination with a monoglyceride and a vegetable oil. Upon contact with an aqueous liquid, the composition forms a reverse hexagonal liquid crystalline phase matrix which releases the active agent in controlled fashion. The method of delivery is particularly useful for the treatment of periodontal disease by insertion of the liquid crystalline phase precursor composition directly into the periodontal pocket, where water from the gingival fluid induces the spontaneous in situ formation of the reverse hexagonal liquid crystalline phase matrix.

  • Patent number: 4424229
    Abstract: Fluorosubstituted benzaldehydes are condensed with anisil and ammonium acetate to yield the corresponding 2-(fluorosubstituted phenyl)-4,5-bis(4-methoxyphenyl)imidazoles. Alternatively fluorosubstituted benzaldehydes are condensed with anisil monoxime and ammonium acetate to yield the corresponding 2-(fluorosubstituted phenyl)-4,5-bis(4-methoxyphenyl)-imidazole-3-oxides which can subsequently be reduced to yield the corresponding 2-(fluorosubstituted phenyl)-4,5-bis(4-methoxyphenyl)imidazoles. These imidazoles have interesting pharmacological properties.

  • Patent number: 4396610
    Abstract: New guanidine derivatives of polyene macrolides having at least one free amino group and at least one free carboxy group (e.g. nystatin, pimaricin, amphotericin B, candicidin and trichomycin) are prepared by reacting the macrolide with a carbodiimide of the formula:R.sup.1 --N.dbd.C.dbd.N--R.sup.2wherein R.sup.1 and R.sup.2 are independently alkyl, substituted alkyl, cycloalkyl, aralkyl, aryl or aroylalkyl. Esters and salts of the derivatives can also be formed. The new derivatives are water-soluble and can be used as anti-mycotic agents.
