White masses or powder, odorless when perfectly dry; deliquescent in the air and exhaling the odor of hydrocyanic acid. Freely soluble in cold water.
Action and Uses: Sodium cyanide replaces potassium cyanide, U.S.P. VIII. The alkaline cyanides are rarely administered internally, but their use in solution has been suggested as a substitute for diluted hydrocyanic acid.
Sodii Glycerophosphas (Sod. Glycerophos.), Sodium Glycerophosphate, U.S.P. (Sodium Glycerinophosphate).—Hydrated sodium glycerophosphate. Represents not less than 68 per cent. of the anhydrous salt.
White, odorless plates, scales or powder, having a saline taste. Very soluble in hot or cold water and nearly insoluble in alcohol.
Action and Uses: Has been recommended in solutions as a nerve tonic in all kinds of wasting and nervous diseases. The weight of evidence indicates that the glycerophosphates are not superior to ordinary phosphates and that the claims for them as nerve tonics are, therefore, unfounded.
Dosage: 0.25 Gm. or 4 grains (U.S.P.).
Elixir Glycerophosphatum Compositum (Elix. Glycerophos. Co.), Compound Elixir of Glycerophosphates, N.F. (Compound Solution of Glycerophosphates).—Solution of sodium glycerophosphate (4%), calcium glycerophosphate (1.6%), ferric glycerophosphate (0.3%), soluble manganese glycerophosphate (0.2%), quinine glycerophosphate (0.1%), strychnine glycerophosphate (0.015%), lactic acid (1%) and compound spirit of cardamom, in alcohol, glycerin and water. Absolute alcohol content about 12 per cent.
Uses: A highly complex and therefore irrational preparation of the inactive glycerophosphates.
Dosage: 8 Cc. or 2 fluidrachms (N.F.).
Liquor Sodii Glycerophosphatis (Liq. Sod. Glycerophos.). Solution of Sodium Glycerophosphate, U.S.P.—Anhydrous sodium glycerophosphate (not less than 50%) in water.
