Colon cleansing compositions
DCFirst Claim
1. A kit comprising:
- (a) a first container containing a first dry composition, said first dry composition comprising;
(i) 90 g to 125 g of polyethylene glycol (“
PEG”
);
(ii) 5 g to 10 g of an alkali metal sulfate, an alkaline earth metal sulfate or a mixture thereof;
(iii) 2 g to 4 g of sodium chloride; and
(iv) 0.5 g to 1.3 g of potassium chloride; and
(b) a second container containing a second dry composition comprising 5 g to 15 g of an ascorbate component, said ascorbate component comprising ascorbic acid and a salt thereof in an ascorbic acid;
salt weight ratio in the range of 2;
8 to 8;
2,wherein the calculated total number of moles of individual dissolved species in a solution made with the contents of the first and second containers made up to one liter with water is within the range of 300 to 700 mmol.

Abstract
A composition comprising, per liter of aqueous solution, from 30 to 350 g polyethylene glycol, from 3 to 20 g of an ascorbic acid component selected form the group consisting of ascorbic acid, a salt of ascorbic acid, or a mixture thereof, an alkali metal or alkaline earth metal sulphate, preferably from 1 to 15 g thereof, and optionally one or more electrolytes selected from sodium chloride, potassium chloride, and sodium hydrogen carbonate, and preferably also comprising flavorings, is effective in cleansing the gut in preparation for a endoscopy, especially colonoscopy. It is safer than conventional sodium phosphate-based gut cleansing compositions, and hence can be used for patients who would be at risk with sodium phosphate-based compositions, and is better tolerated than conventional PEG-based compositions, leading to better patient compliance and enabling effective out-patient use.
