  • Publication number: 20190000768
    Abstract: There are manufactured an enteric capsule comprising: a seamless capsule consisting of a capsule fill and a shell layer; and an enteric coating layer on the shell layer, the enteric coating layer comprising one selected from a methacrylic acid-based polymer, polyvinyl acetate phthalate, organic acid ester of hydroxypropylmethylcellulose, carboxymethylethylcellulose, and cellulose acetate phthalate; and an enteric seamless capsule further comprising a subcoating layer between the shell layer of the seamless capsule and the enteric coating layer, the subcoating layer consisting of hydroxypropylcellulose and the like. The enteric seamless capsule has acid resistance and also enables controlled dissolution for each application site in the body.

  • Patent number: 9820947
    Abstract: An object is to provide a method of manufacturing a seamless soft capsule that is enteric and excellent in formulation properties. An enteric seamless soft capsule is manufactured by the following steps (a) and (b): (a) preparing an enteric capsule shell liquid comprising gelatin and low methoxy pectin having a degree of esterification of 0 to 40% and a degree of amidation of 0 to 25%, the enteric capsule shell liquid having a viscosity at 50° C. of 60 to 127 mPa·s; and (b) encapsulating capsule fills with the enteric capsule shell liquid prepared in the step (a) by dripping. Preferably, the jelly strength of the gelatin is 180 to 330 Bloom, an aqueous solution of the low methoxy pectin at a concentration of 2 mass % has a viscosity at 35° C. of 8 to 15 mPa·s, and the enteric capsule shell liquid comprises 10 to 20 parts by mass of the low methoxy pectin per 100 parts by mass of gelatin.
