Elixir of valerianate of ammo nium with cinchonine and pyrophosphate of iron, 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 of valerianate of ammonium with cinchonine and pyrophosphate of iron. Observe precautions suggested with elixir of valerianate of ammonium with cinchonidine and pyrophosphate of iron.
Each fluidrachm (teaspoonful) of the finished elixir contains two grains of valerianate of ammonium, one grain of pyrophosphate of iron, one-half grain of cinchonine, and one-hundredth of a grain of strychnine. The alkaloids exist as acetates. This preparation should be as nearly neutral in reaction as it is possible to make it.
