Method for preparing colloidal solution of bismuth sodium tartrate

Abstract

A method for preparation of a semitransparent colloidal solution of bismuth sodium tartrate generally comprises producing an aqueous solution of bismuth sodium tartrate; extracting a magma of bismuth sodium tartrate from the aqueous solution at a pH of approximately 2.2; and then dissolving the magma into a salting-in mixture. After addition of preservative and strength testing, the base solution is diluted to elixir strength. The elixir is then buffered to a pH range of about 7.2 to about 7.3 in order to maintain for an extended duration the semitransparent nature of the elixir.
