CLEAR BISMUTH TREATMENTS AND METHODS FOR MAKING

摘要

Applicants' invention relates to methods of making and using a bismuth sodium tartrate solution for treating parvovirus, colic and other gastro-intestinal disorders, involving the preparation of a clear pharmaceutical bismuth solution through careful processing and the use of a salting-in process to obtain the resulting solution, starting with an aqueous solution of bismuth sodium tartrate, extracting a highly acidic precipitate of bismuth sodium tartrate from the aqueous solution, dissolving the precipitate into a salting-in mixture to form a transparent or semitransparent colloidal solution of bismuth sodium tartrate; adding a preservative and diluting it appropriately to produce a safe and effective, orally-administered liquid bismuth pharmaceutical that is clear in appearance and texture.
