ELECTROLYTE PURGATIVE
The invention relates to compositions for use in purgatives, to purgatives comprising such compositions, and to methods for inducing purgation of the colon. The composition may comprise at least one water-soluble sodium salt; at least one water-soluble minimally degradable sugar in an amount, by weight, of from about 1 to about 3 times the weight of sodium ions in said composition; at least one water-soluble potassium salt in an amount, by weight, of from about 0.05 to about 1 time the weight of said sodium salt in said composition; and at least one water-soluble magnesium salt, wherein the weight of magnesium ions in said composition is from 0.1 to about 10 times the weight of sodium ions in said composition.

43 . The purgative composition of claim 37 , further comprising at least one composition or additive selected from the group consisting of a flavoring ingredient, a detergent stool-softening agent, citrate, lactate, acetate, a trace element and a nutritional element.
44 . The purgative composition of claim 37 , in the form of, or formulated as: a medicament, a soup or soup-like composition, a tablet, a gel cap, a capsule, a sachet, a hypertonic aqueous solution or a lavage solution.
45 . The purgative composition of claim 37 , in the form of a unit dose having a volume of from about 0.2 to 0.5 L and wherein the sodium salt or salts are present in an amount from about 1 to about 10 g per unit dose, the minimally degradable sugar or sugars in an amount of from about 2 to about 20 g, the potassium salt or salts in an amount of from about 0.5 to about 5 g and the magnesium salt or salts in an amount of from about 1 to about 10 g per unit dose of the purgative composition.
46 . A method of inducing purgation of the colon of a patient in need thereof, comprising administering to the patient a purgative composition of claim 37 , in an amount effective to induce purgation of the patient's colon.
47 . A method of inducing a pre-surgical lavage of the colon of a patient in need thereof, comprising administering to the patient a purgative composition of claim 37 , in an amount effective for pre-surgical lavage of the patient's colon.
48 . The purgative composition of claim 37 , further comprising one or more compositions comprising a citrate, a lactate, an acetate, a calcium, a zinc, a Vitamin B complex, a thiamine, a Vitamin A, a Vitamin C, a Vitamin E, a folic acid or a biotin or a mixture thereof.
