摘要:
A granule of drug to remain in the stomach comprises a core comprising a pharmaceutically effective ingredient, a foaming layer coated on said core and an expansive film coated on said layer.
摘要:
A sustained-release multi-granule tablet is obtained by compressing sustained-release granules, which contains a basis, and a formulation adjuvant. Each of the granules has been coated in advance with a layer of the formulation adjuvant and/or a layer of a mixture of the formulation adjuvant and the basis. The tablet releases an active substance at a suitable velocity into the digestion tract, resulting in that the inbalance in the absorption of the drug in each patient and among individual patients is minimized to achieve maximum bioavailability.

摘要:
A multilayer granule of the invention comprises a core, a slow-release layer, a rapid-release layer to be provided outer of said slow-release layer and a film layer containing a metal stearate and being deposited between the slow-release layer and the rapid-release layer. A pharmacologically effective component is kept to discharge for long.
摘要:
A conjugate formed by the covalent bonding of a prostaglandin or a similar compound thereto and a polysaccharide. The prostaglandin is selected from prostaglandin E1, prostaglandin E2, prostaglandin F2.alpha., prostaglandin I2, carbacycline and iloprost and the polysaccharide is selected from pluran, amylose, amylopectin, cellulose, dextran and hydroxyethylated starch.

A sustained-release drug preparation comprises a water-soluble drug, a lipidic substance and an oil as its essential components. The drug level in the blood is sustained at a preferable concentation for a long period of time.
摘要:
A fuel cell system, comprising: (A) a cell multilayer element that is formed by stacking unit cell structures in layers, a unit cell structure including: a cell that includes a cathode, an anode, and electrolyte sandwiched between the cathode and the anode an oxidant channel unit with a plurality of oxidant channels that cross the cathode and enable oxidant to be supplied to the cathode; and a fuel channel unit with a plurality of fuel channels that cross the anode and enables fuel to be supplied to the anode; (B) oxidant supplying means for supplying the oxidant to the oxidant channels; and (C) fuel supplying means for supplying the fuel to the fuel channels, wherein the oxidant supplying means includes first switching means for reversing a flow direction of the oxidant in at least one of the oxidant channels and/or the fuel supplying means includes second switching means for reversing a flow direction of the fuel in at least one of the fuel channels.
摘要:
The object of the present invention is to provide fuel cell including a cell that is formed by sandwiching solid polymer membrane between an anode and a cathode that generates electricity with stability and high performance by evenly moistening the solid polymer membrane. For this purpose, in a gas diffusion layer 24, which is positioned adjacent to a cathode catalyst layer 22, the content of fluororesin in an area on the side of the entrance for the oxidizer is set to be higher than in another area on the side of the exit so that the water repellency in the entrance side area is higher than in the exit side area. As a result, a water permeation suppressing part 24A, where the water permeability is relatively low, is formed in the area on the entrance side, while a water permeable part 24B, where the water permeability is relatively high, is formed in the area on the exit side.
