  • Patent number: 7858112
    Abstract: The present invention provides a percutaneous absorption system and a percutaneous absorption method, which have a simple constitution and can realize the easy and continuous percutaneous absorption of medicine even when the medicine is formed of a water-soluble oligomer solution or a high-molecular solution. In the percutaneous absorption system comprising a medicine reservoir portion having a medicine holding portion which holds medicine therein and a support portion for supporting the medicine reservoir portion, the support portion including an adhesive layer and a substrate having medicine non-permeating property, the system is provided with an elastic member for applying pressure to the medicine held in the inside of the medicine reservoir portion, and by breaking the substrate having medicine non-permeating property in the support portion using a mechanical stimulus such as an injection needle or the like, the medicine is released (delivered) at a fixed rate.

  • Publication number: 20050143476
    Abstract: The invention aims to provide an emulsion composite which is excellent in safety and stability and which can easily be produced. 20 g of soybean oil and 2.4 g of glycerin were mixed by being stirred with a magnetic stirrer. The mixture was added to strong alkali ionic water to adjust the total amount to 200 g. The solution was subjected to primary emulsification in a boiling water bath at 12,765 rpm for a stirring time of 30 minutes using an autohomomixer. Necessary amounts of strong alkali ionic water and glycerin were then added such that the volume and the osmotic pressure became predetermined values. This sample was subjected to secondary emulsification at a pressure of 1,000 bar with 40 pass times using a high-pressure homogenizer to prepare an O/W emulsion (emulsion composite).
