Claims59
A powdered effervescent laxative composition, the powdered composition comprising:
- about 70 weight percent or more of polyethylene glycol having a weight average molecular weight of between about 3,000 and about 4,000 g/mol;
- an effervescent system including (i) an acid component selected from the group consisting of monosodium citrate, disodium citrate, trisodium citrate, maleic acid, fumaric acid, adipic acid, and combinations thereof and (ii) an alkaline component selected from the group consisting of sodium bicarbonate, sodium carbonate, potassium bicarbonate, potassium carbonate, calcium bicarbonate, calcium carbonate, and combinations thereof;
- and
- wherein the effervescent system has a molar ratio of (i) the acid component to (ii) the alkaline component of about 1:1 to about 1:4.
