preparation example 1
[0204] Preparation of sustained-release part (core matrix tablet)
[0205] Lansoprazole (hereinafter sometimes referred to as compound A; 6.0 g), hydroxypropylmethylcellulose (trade name: Metolose 90SH-100SR, manufactured by Shin-Etsu Chemical Co., Ltd., 6.67 g), D-mannose Sugar alcohol (5.07 g), crystalline cellulose (trade name: Ceolus PH-101, manufactured by Asahi Kasei Chemicals, 4.59 g), magnesium stearate (0.23 g), and Aerosil (1.1 g) were mixed in a mortar. The resulting mixture (170 mg) was compressed into tablets using a hydraulic pump press (manufactured by Riken Seiki) (Tablet pressure: 1 ton / cm 2 ), thereby obtaining a core skeleton sheet with a diameter of 7 mm. It is used as the sustained-release part of the solid preparation of the present invention.
preparation example 2
[0207] Preparation of Immediate Release Partial Granular Powders
[0208] Compound A (10g), calcium carbonate (166.67g) and D-mannitol (155.8g) were loaded in a fluidized bed granulator, and hydroxypropyl cellulose (13.87g) was dissolved in purified water (231.11g) The aqueous solution in ® was sprayed, the mixture was granulated, and the granules were dried to obtain a granulated powder (340 g) for the immediate release portion.
