prepared into the resulting clear solution maltodextrin was added with agitating at room temperature using this formulation the stability test for the aqueous solution of the mixture of various bile acids which can control the hydrophillicity or hydrophobicity was conducted the following solution dosage forms were prepared and they did not show any precipitation at any ph 80 ml of the aqueous solution in which soluble udca is dissolved was prepared and then maltodextrin as one of high molecular weight aqueous soluble starch conversion products was added into the clear solution with agitating at room temperature into the resulting clear solution sweetener preservatives and flavoring agents were added in quantities suitable for a pharmaceutical formulation purified water is added to make total 100 ml in these formulas the aqueous solution dosage forms of various concentrations of ursodeoxycholic acid or its salts with its corresponding minimal quantity or more of high molecular weight aqueous soluble starch conversion products for example maltodextrin liquid glucose dextrin dextran or soluble starch were prepared the minimal corresponding quantity of maltodextrin for the various amounts of udca in this solution preparation are as follows for 0 2 g of udca approx 5 g of maltodextrin for 0 4 g of udca approx 10 g of maltodextrin for 1 g of udca approx 25 g of maltodextrin for 2 g of udca approx 50 g of maltodextrin the minimal corresponding quantity of liquid glucose for the various amount of udca are as follows for 0 2 g of udca approx 16 g of liquid glucose for 0 5 g of udca approx 80 g of liquid glucose.
