Elixir of phosphate of iron and quinine, 16 fluidounces.
Strychnine, 1 1/4 grains.
Acetic acid, a sufficient quantity.
Triturate the strychnine in a mortar with acetic acid in amount sufficient to effect its solution, and then add the elixir. Filter if necessary.
Each fluidrachm (teaspoonful) of the finished elixir contains one-half grain each of phosphates of iron and quinine, and one-hundredth of a grain of strychnine.
In 1878 Mr. J. Creuse contributed an article to the Druggists' Circular regarding a preparation sold under the name of the foregoing elixir, which proved to be an elixir of pyrophosphate of iron. It is also true that other preparations containing pyrophosphate of iron are sometimes dispensed where phosphate is specified, and physicians should be careful and use the abbreviation phos. only when the phosphate is desired.
