る。(Prior Art) Bandages for intraoral application have been prepared for the purpose of protecting damaged or diseased areas in the oral cavity or for the purpose of absorbing certain medicinal ingredients into the body through the oral mucosa. Bandages for intraoral application are required to be able to be applied to moist oral mucosa and not to be easily peeled off due to saliva secretion, eating and drinking, etc. As a bandage for intraoral application, for example, Japanese Patent Publication No. 5B-7605
The publication discloses a bandage for intraoral application having a composition containing hydroxypropyl cellulose and an acrylic acid (co)polymer or a salt thereof. Japanese Patent Publication No. 59-1869
No. 13 discloses a bandage for intraoral application having a composition containing gelatin or agar, gluten, carboxyvinyl polymer, and vinyl acetate or gums. JP-A-60215622 discloses a bandage for intraoral application having a composition containing polyvinylpyrrolidone, polyvinyl alcohol, polyethylene glycol, alginic acid or its salt, maleic anhydride-methyl vinyl ether copolymer, and acrylic acid (co)polymer. is disclosed. JP-A-60-142927 discloses a bandage for intraoral application having a composition containing chitosan or a chitosan derivative. JP-A-61-249473 discloses a bandage for intraoral application having a composition containing polycarboxylic acid, polycarboxylic anhydride, and vinyl acetate copolymer.

付性基剤の粘膜への付着性が低下するという欠点がある
。The bandages disclosed in each of the above-mentioned publications all have a base layer containing a hydrophilic polymer as a main component. Such hydrophilic polymers become sticky when a small amount of water such as saliva is added to them in the oral cavity, and adhere to the oral mucosa. However, hydrophilic polymers tend to swell and disintegrate due to excess water from saliva or eating and drinking. In order to compensate for this lack of water resistance, the above publications all use water-insoluble or poorly water-soluble polymers in addition to hydrophilic polymers.
is contained in the base. However, since the water-insoluble (poorly soluble) polymer is present, although the water resistance is improved, there is a drawback that the adhesion of the mucosal adhesive base to the mucous membrane is reduced.

性基剤から非貼付性基剤が剥離し易くなるという欠点が
ある。Furthermore, a bandage with a two-layer structure consisting of a mucosal adhesive base and a water-resistant non-mucosal adhesive base has also been proposed. However, in order to impart water resistance to a non-mucosal adhesive base, the main component of this base must be hydrophobic, and for this reason, it lacks compatibility with mucosal adhesive bases. There is a drawback that the non-stick base tends to peel off from the sticky base when it contains water.
また、貼付後もバンデージが柔らかすぎるため、飲食や
会話による物理的な影響を受は易く、バンデージが粘膜
から剥離し易いという欠点がある。Furthermore, since the bandage is too soft even after application, it is susceptible to physical effects from eating, drinking, and talking, and has the disadvantage that the bandage is easily peeled off from the mucous membrane.
このように、口腔粘膜への付着性が良好であり、かつ、
充分な耐水性を有する口腔内貼付用バンデージは得られ
ていないのが現状である。In this way, it has good adhesion to the oral mucosa, and
At present, a bandage for intraoral application with sufficient water resistance has not been obtained.

うになる。The hydrophilic polymer contained in the mucous membrane adhesive base layer is a polymer having acidic groups such as carboxyl groups, hydroxyl groups, and sulfonic acid residues. These polymers are soluble in water and at least one type of solvent that is miscible with water (for example, highly polar solvents such as alcohols, acetone, and acetonitrile). Examples of such polymers include poly(meth)acrylic acid, poly(meth)acrylic anhydride, maleic anhydride (co)polymer, and the like. These polymers absorb small amounts of moisture and become highly adhesive, as described in the prior art section.

In the present invention, this chitosan and its derivatives (including chitin, chitosan salts, and chitosan derivatives) are used (hereinafter, chitosan and its derivatives will be referred to as "chitosan j").Such "chitosan" exists in an undissolved state in the mucosal adhesive base. For example, it is preferable to use it in the form of particles or short fibers. If it is particulate, 100

付着性に劣る。Moreover, in the case of short fibers, it is preferable that the fiber diameter is 10 IIm or less and the fiber length is 1 mm or less. This "chitosan" and the above-mentioned hydrophilic polymer have a weight ratio of 5:95 to 7.
Mixed at a ratio of 0/30. If the hydrophilic polymer is too much and the chitosan is too little, the resulting bandage will have poor water resistance. On the other hand, there is too little hydrophilic polymer,
If the amount of "chitosan" is excessive, the adhesion of the bandage to the oral mucosa will be poor.

い。(Function) The mucosal adhesive base of the bandage exhibits strong mucoadhesive force by absorbing a small amount of water using a hydrophilic polymer. In addition, after application, the "chitosan" contained in the base material interacts with the acidic groups of the hydrophilic polymer due to moisture from the mucous membrane and the outside, and as a result, the hydrophilic polymer becomes insoluble in water. By forming and maintaining an elastic body, it is highly effective in covering and protecting damaged and diseased areas in the oral cavity.

基剤であることから、単独の使用でも長時間にわたり口
腔内粘膜表面に貼付することが可能となる。Although this interaction is not clear, "chitosan"
This is thought to be due to the bond between Chitosan J and the hydrophilic polymer, which is caused by ionic bonding or hydrogen bonding between the amino group of the chitosan and the acidic group of the hydrophilic polymer, such as the carboxyl group. When the compound is further present, such effects are enhanced.Thus, since it is a mucosal adhesive base with excellent adhesiveness, water resistance, and shape retention, it is difficult to use it alone. However, it can be applied to the oral mucosal surface for a long period of time.
また、粘膜貼付性基剤に含有される「キトサン」により
抗菌・抗ウイルス効果及び創傷治癒促進効果も期待され
る。Furthermore, the "chitosan" contained in the mucosal adhesive base is expected to have antibacterial and antiviral effects and wound healing promoting effects.

能となる。Furthermore, after the mucosal adhesive base adheres to the mucous membrane, it is irradiated with light and the photosensitive resin is cured, thereby reducing the amount of moisture absorbed by the mucosal adhesive base per unit time and maintaining the shape when applied. By doing so, it is less susceptible to physical influences in the oral cavity, so it has superior water resistance and durability compared to a mucosal adhesive base alone, and can be stably adhered for a longer period of time.
また、このバンデージは、貼付時は柔軟なシート状であ

ための基剤として有用である。(Effects of the Invention) According to the present invention, an intraoral patch bandage that exhibits excellent adhesion to the oral mucosa and has excellent water resistance and durability is provided. This bandage is in the form of a flexible sheet, so it does not cause discomfort when applied, and after application, the mucosal adhesive base absorbs water from the mucous membrane to form and maintain an elastic body, allowing it to be used in the oral cavity. The effect of covering and protecting damaged and diseased areas is increased. Furthermore, by curing the photosensitive resin after application, it retains its shape at the time of application and makes the mucosal adhesive base less susceptible to external physical influences, allowing it to adhere stably for a long time. It has the effect of sufficiently protecting the mucous membrane area to which it is applied. Such bandages can be applied to the surface of the oral mucosa for a long period of time, and can be used to sufficiently protect damaged or diseased areas in the oral cavity, and can also absorb medicinal ingredients transmucosally, allowing them to be absorbed throughout the body. It is useful as a base for expressing sexual and local effects.
