Patent number: 9040564Abstract: It is intended to provide a pharmaceutical composition which contains a proton pump inhibitor and is stable even if it is stored for a long time. It is also intended to provide a pharmaceutical composition which contains a proton pump inhibitor susceptible to acid, and does not dissolve in the stomach but dissolves in the intestine to release a primary drug product promptly. The object could be achieved by the pharmaceutical composition characterized in that a layer containing a proton pump inhibitor and ethyl cellulose, a layer containing an enteric polymer, and if necessary an intermediate layer composed of one or more layers are formed on a pharmacologically inactive core substance. The intermediate layer is composed of a water-insoluble polymer, a water-soluble polymer, a lubricant and the like.Type: GrantFiled: November 8, 2007Date of Patent: May 26, 2015Assignee: EISAI R&D MANAGEMENT CO., LTD.Inventors: Koji Ukai, Norishige Takami

Patent number: 8252362Abstract: Evaluation methods that employ the near infrared spectrum have generally had a low specificity and in particular have encountered difficulty in the evaluation of trace components, and the accurate measurement of coating quantity by methods using the near infrared spectrum has been quite problematic. The quantity of coating applied to a coating target, such as granules or uncoated tablets, is measured based on the absorption or scattering of light in the 800 to 1100 nm wavelength region by an additive coated on the coating target. The use of polyethylene glycol or a long-chain hydrocarbyl-containing compound as the additive is preferred.Type: GrantFiled: February 2, 2006Date of Patent: August 28, 2012Assignee: Eisai R&D Management Co., Ltd.Inventors: Makoto Yokoyama, Koji Ukai
