Compositions for pharmaceutical and other uses comprising clear aqueous
solutions of bile acids which do not form any detectable precipitates
over selected ranges of pH values of the aqueous solution and methods of
making such solutions. The compositions of the invention comprise water;
a bile acid in the form of a bile acid, bile acid salt, or a bile acid
conjugated with an amine by an amide linkage; and either or both an
aqueous soluble starch conversion product and an aqueous soluble
non-starch polysaccharide. The composition remains in solution without
forming a precipitate over a range of pH values and, according to one
embodiment, remains in solution for all pH values obtainable in an
aqueous system. The composition, according to some embodiments, may
further contain a pharmaceutical compound in a pharmaceutically effective
amount. Non-limiting examples of pharmaceutical compounds include
insulin, heparin, bismuth compounds, amantadine and rimantadine.
