摘要： A pharmaceutical preparation in the form of a coated capsule which can release contents of a capsule at a lower part of the digestive tract comprising (a) a hard capsule containing at least an acidic substance, (b) a polymer film soluble at low pH which is formed on a surface of said hard capsule, and (c) an enteric coating film which is formed on a surface of said polymer film soluble at low pH. According to the pharmaceutical preparation of the present invention, any kind of a medicament can be delivered to any desired site between the upper part of the small intestine and the lower part of the large intestine in the digestive tract by controlling the amount of polymer(s) used for the polymer film soluble at low pH and/or by selecting the kind of the polymer film soluble at low pH and/or the acidic substance without any complicated requirements for each medicament.

摘要： A preparation capable of releasing a medicinal substance at a targeted site in the intestine, wherein the preparation dose not releases medicinal substance in endogastri at all, but can quickly release a medicinal substance when it reaches the desired site in the intestine after a certain period of time from discharge of the preparation from the stomach, and wherein a core material containing a medicinal substance is coated with a mixed film of a hydrophobic organic compound—an enteric polymer. The preparation is useful for a local therapy of inflammatory disease in the intestine such as ulcerative colitis or Crohn's disease, or an oral administrative therapy with a medicinal substance of a peptide which is apt to be decomposed chemically or enzymatically in any site except for a specific site in the intestine such as the large intestine, or with a medicinal substance whose absorption site in the intestine is limited, or the like, because a medicinal substance can be delivered selectively to a specific site in the intestine.
