ORALLY ADMINISTRABLE TABLET FOR INTESTINAL LAVAGE

摘要

Disclosed is an orally administrable tablet for intestinal lavage, which is small in size and can be administered easily. The orally administrable tablet for intestinal lavage does not leave a residue in the intestinal tract after the intestinal lavage, and has dissolvability equivalent to that of conventional sodium phosphate-containing tablets in which crystalline cellulose is blended. Specifically disclosed is an orally administrable tablet for intestinal lavage, which contains the following components (A) and (B), while having a water-insoluble content of not more than 5% by mass. (A) 80-95% by mass of sodium phosphate (B) (B1) 7-11% by mass of hydroxypropylcellulose, not less than 99% of which passes through a mesh with openings of 350 µm, and a 2% by mass aqueous solution of which has a viscosity of 2.0-10.0 mPa·s; (B2) 5-13% by mass of hydroxypropylcellulose, not less than 99% of which passes through a mesh with openings of 150 µm, and a 2% by mass aqueous solution of which has a viscosity of 3.0-5.9 mPa·s; or (B3) 7-11% by mass of hydroxypropylcellulose, not less than 99% of which passes through a mesh with openings of 150 µm, and a 2% by mass aqueous solution of which has a viscosity of 6.0-4000 mPa·s
