Patent ID: 8454995

Claim:
A method for bowel cleansing, comprising administering to a patient in need thereof a peroral tablet comprising: (A) 80 to 95 mass % of sodium phosphate, wherein the sodium phosphate (A) comprises sodium dihydrogenphosphate monohydrate and disodium hydrogenphosphate anhydrate, and wherein a content of sodium dihydrogenphosphate monohydrate is 70 to 75 parts by mass and a content of disodium hydrogenphosphate anhydrate is 25 to 30 parts by mass when a total amount of sodium dihydrogenphosphate monohydrate and disodium hydrogenphosphate anhydrate is 100 parts by mass; and (B) a cellulose comprising at least one selected from the group consisting of (B1) 7 to 11 mass % of a hydroxypropyl cellulose having particle sizes such that >99% of particles thereof pass through a mesh having an opening of 350 gm and whose 2-mass % aqueous solution has a viscosity of 2.0 to 10.0 mPa.s, (B2) 5 to 13 mass % of a hydroxypropyl cellulose having particle sizes such that >99% of the particles thereof pass through a mesh having an opening of 150 gm and whose 2-mass % aqueous solution has a viscosity of 3.0 to 5.9 mPa.s, and (B3) 7 to 11 mass % of a hydroxypropyl cellulose having particle sizes such that >99% of the particles thereof pass through a mesh having an opening of 150 jam and whose 2-mass % aqueous solution has a viscosity of 6.0 to 4,000 mPa.s, wherein the peroral tablet has a water insoluble ingredient content of 5 mass % or less.
