Abstract

The present disclosure is related to clear aqueous solutions of one or more bile acids and either an aqueous soluble starch conversion product or a non-starch polysaccharide. Solutions of the disclosure may be administered to a subject in conjunction with a pharmaceutical compound having one or more toxic effects. In some embodiments, solutions of the disclosure are administered to a mammal in conjunction with a pharmaceutical compound associated with a peripherial neurotoxicity (e.g., cisplatin and/or suramin) to reduce or eliminate the neuropathic effect(s).

Claims
