    摘要： The present invention presents a pharmaceutical composition for oral use with improved absorption, which comprises drug, aminoalkyl methacrylate copolymer E, and acidic substance and is obtained by bringing said 3 components together and uniformly mixing at least this polymer and this acidic substance, and a method of improving oral absorption/by using this pharmaceutical composition. Moreover, the present invention presents an agent for improving oral absorption that increases drug permeability of the digestive tract mucous membrane and/or mucous layer present on the surface of this membrane, whose active ingredient is aminoalkyl methacrylate copolymer E. In addition, the present invention presents an oral agent for improving absorption by increasing drug permeability of the digestive tract mucous membrane and/or the mucous layer distributed over this mucous membrane, whose effective component is aminoalkyl methacrylate copolymer E.

    摘要： The present invention is to provide a stable pharmaceutical composition for oral use and preparation thereof in which changes are prevented in drug release at stored even under the exposure to light by adding yellow ferric oxide and/or red ferric oxide in a matrix type sustained-release preparation containing a drug, hydrophilic base, and polyethylene oxide. The present invention is to further provide a method for preventing changes in drug release at stored under the exposure to light in a matrix type sustained-release preparation containing a drug, hydrophilic base, and polyethylene oxide. The quality assurance period of the product can be prolonged and the product value can be improved by the present invention.

    摘要： The present invention was completed based on these discoveries and relates to in a hydrogel-forming compression-coated solid pharmaceutical preparation comprising a core tablet containing drug and outer layer made from hydrogel-forming polymer substance and hydrophilic base, the improvement, a timed-release compression-coated solid composition for oral administration, said composition comprising (1) drug and freely erodible filler are mixed with the core tablet, (2) the percentage erosion of the core tablet is approximately 40 to approximately 90%, and (3) the outer layer essentially does not contain the same drug as the above-mentioned drug. By releasing a drug after a specific lag time, it becomes possible to effectively deliver a drug to a specific site in the digestive tract. It is therefore useful as presented as a timed-release solid composition for oral administration of a drug that is to be effectively delivered in high concentrations to the afflicted site in the lower digestive tract, a drug that is to be effectively absorbed in the lower digestive tract, a drug that is effective for chronopharmacotherapy, etc.
