  • Patent number: 5128138
    Abstract: A mixture of estradiol or other estrogen and an uncrosslinked, water-insoluble vinylpyrrolidone copolymer provides a matrix which gradually releases the medicament upon application to the skin of a patient in the form of an ointment, gel or film. The polymer provides for the slow and sustained release of the medicament upon topical application to the skin so that the concentration of drug in the blood plasma of the patient is maintained within the levels required for clinical efficacy.

  • Patent number: 5086077
    Abstract: A novel endermic medicament having a consistency of a gel is proposed which is formulated, as a gel base, with non-ionic water-soluble cellulose ether, e.g., methyl cellulose and hydroxypropyl methyl cellulose, modified with a modification agent containing, in the molecule, an alkyl group having 6 to 26 carbon atoms and a functional group having reactivity with the hydroxyl group in the cellulose ether, e.g., stearyl glycidyl ether, decyl glycidyl ether and cetyl epoxide. The endermic medicament formulated with the modified cellulose ether is stable by virtue of the very little interaction between the active ingredients and the gel base and also can exhibit high percutaneous absorptivity of the active ingredients through the human skin.
