    • Use of fatty acid esters as bioadhesive substances. The fatty acid esters have molecular weights below about 1000 dalton and the fatty acid component of the fatty acid ester is a saturated or unsaturated fatty acid having a total number of carbon atoms of from C.sub.8 to C.sub.22. Particularly suitable fatty acid esters for use according to the invention are fatty acid esters which are selected from the group consisting of fatty acid esters of polyhydric alcohols, fatty acid esters of hydroxycarboxylic acids, fatty acid esters of monosaccharides, fatty acid esters of glycerylphosphate derivatives, fatty acid esters of glycerylsulfate derivative, and mixtures thereof. Excellent bioadhesive properties have been observed for fatty acid esters are glyceryl monooleate, glyceryl monolinoleate or glyceryl monolinolenate.Methods are described for administering an active or protective substance to undamaged or damaged skin or mucosa of an animal such as a human by combining the active or protective substance with a bioadhesive fatty acid ester. The mucosa may be the oral, aural, nasal, lung, gastrointestinal, vaginal, or rectal mucosa. The administration may also be to body cavities such as the oral cavity, e.g. via buccal administration.
    • 使用脂肪酸酯作为生物粘附物质。 脂肪酸酯的分子量低于约1000道尔顿,脂肪酸酯的脂肪酸组分是碳原子数为C8〜C22的饱和或不饱和脂肪酸。 根据本发明使用的特别合适的脂肪酸酯是选自多元醇的脂肪酸酯,羟基羧酸的脂肪酸酯,单糖的脂肪酸酯,磷酸甘油酯衍生物的脂肪酸酯, 甘油硫酸酯衍生物的脂肪酸酯及其混合物。 已经观察到对于脂肪酸酯具有优异的生物粘合性质,是单油酸甘油酯,单烯醇甘油酯或甘油单苯三酸盐。 描述了通过将活性或保护性物质与生物粘附性脂肪酸酯组合来将活性或保护性物质施用于动物如人的未损伤或损伤的皮肤或粘膜的方法。 粘膜可以是口服,听觉,鼻,肺,胃肠道,阴道或直肠粘膜。 给药也可以是体腔,例如口腔,例如。 通过口腔管理。
