    摘要: A clonidine preparation for percutaneous administration comprising a support having provided thereon an active ingredient-containing layer is disclosed. The active ingredient-containing layer contains an acrylic polymer having a glass transition temperature of from -70.degree. C. to -10.degree. C. and pressure-sensitive adhesion at room temperature as a base, at least one of clonidine and clonidine hydrochloride as an active ingredient, and a decomposition inhibitor. The active ingredient can be stably maintained within the preparation without being decomposed, and, therefore, can be effectively released over a prolonged period of time.

    摘要: A vasodilator product having a sustained releasing function is produced by mixing and kneading an atoxic agent having vasodilating activity with a setting or thermoplastic resin and then molding them to form the molded product.Further, the vasodilator can be molded integratedly together with a medical device to be implanted into a human body. These vasodilators can be used not only for an operation of cerebral aneurysm, but also for drainage and vasodilator after microvascular anastomosis and endarterectomy.

    摘要: A mucous membrane-adhering film preparation wherein the film consists of two layers. One layer of the film consists of the pharmaceutical agents and water-soluble high polymer material. The other layer of the film material consists of poor water-soluble agents. The pharmaceutical agent and water-soluble high polymer material layer first layer and the poor water-soluble agents second layer are separately prepared in solvents. The first solution is coated on a base plate having a favorable releasing nature, and, by removing the solvent, the film is produced on the base plate, the second solvent is then coated on the first layer and by removing the solvent, the desired film having one poor water-soluble surface is produced.
