    摘要： A polycarboxylic acid or anhydride, e.g. acrylic or methacrylic acid polymer or maleic anhydride polymer, is mixed with a vinyl acetate polymer preferably of viscosity-average molecular weight of at least 60,000, and optionally with a base capable of neutralising the acid or anhydride, e.g. a salt of a metal or a weak acid. The mixture in a mutual organic or aqueous organic solvent is cast on a sheet base and dried and peeled off to form an oral bandage, which may include a soft film support.
    The bandage shows strong adhesion for a period of at least 3 hours to the oral mucosa or teeth.
    A topical drug can be incorporated in the adhesive bandage, to form an oral pharmaceutical preparation from which the drug is gradually released.
