| 摘要 |
The present invention is directed to a bowel lavage composition which comprises one or more of a water-soluble polymer selected from the group consisting of polyethylene glycol, dextran, dextrin, hydroxyethylated starch, polydextrose, arabic gum, pullulan and pectin; a sodium salt of an organic acid; a potassium salt of an organic acid; sodium chloride; potassium chloride and sodium sulfate, having the following formulation: Water-soluble polymer 10 - 150 g Sodium salt of an organic acid 5 - 60 mmol Potassium salt of an organic acid 0 - 12 mmol Sodium chloride 7 - 60 mmol Potassium chloride 0 - 12 mmol Sodium sulfate 0 - 20 mmol wherein total potassium ion content in said composition ranges from 2 to 12 mEq. The bowel lavage composition is easily prepared in the form of a lavage solution when used. It is easily taken by patients, has reduced absorption of water, does not exert influence upon the electrolyte balance in a living body, has an excellent cleansing effect, does not contain hydrogen carbonate ions, and hence, is pharmaceutically stable and can be stored for a long period of time.
