    • PURPOSE: A process of preparing a drug which is improved in dissolution and oral absorption characteristics by binding a drug which is unstable in the stomach and susceptible to disintegration during absorption to fine particles having a particle size of 10 to 12 μm, together with an absorption enhancer is provided which can prevent inconvenience and adverse side-effects associated with its use and increase bioavailability of drugs which cause its use value to degrade by the loss of activity when administered orally. CONSTITUTION: To improve biodegradability of salmon calcitonin, protein, peptide material and a drug, the drug is dissolved in a mixed solution of methanol, ethanol, acetone, isopropanol, etc. and then mixed with an absorption enhancer such as bile acid, bile salts, transferrin, folic acid, etc. and a biodegradable polymer. Thereafter, the mixed solution is dispersed in an aqueous solution, heated at 40deg.C for 1hr, centrifuged and dried.
    • 目的:制备药物的制备方法,其通过将吸收期间不稳定并容易崩解的药物与粒径为10〜12μm的细颗粒结合使用,吸收改善了溶出度和口服吸收特性, 提供增强剂,其可以防止与其使用相关的不便和不良副作用,并增加药物的生物利用度,其通过口服给药时其活性丧失导致其使用价值降低。 构成:为了提高鲑鱼降钙素,蛋白质,肽材料和药物的生物降解能力,将药物溶解在甲醇,乙醇,丙酮,异丙醇等的混合溶液中,然后与吸收增强剂如胆汁酸,胆汁盐 ,转铁蛋白,叶酸等,以及可生物降解的聚合物。 此后,将混合溶液分散在40℃加热1小时的水溶液中,离心并干燥。
