ACTION AND USES: Used for the oral administration of calcium. Employed in hemorrhagic conditions, in which it is probably useless. Has also been advised in inflammatory conditions of the skin and mucous membranes (urticaria, serum-rashes, hay-fever, etc.). DOSAGE: 0.5 Gm. or 8 grains (U.S.P.), in solution. =Calcii Glycerophosphas (Calc. Glycerophos.), Calcium Glycerophosphate, U.S.P.= (Calcium Glycerinophosphate).--CaC{3}H{7}O{6}P. White, odorless, almost tasteless powder. Soluble in water (1:50) and insoluble in alcohol. ACTION AND USES: Formerly believed to be a tonic, and used especially in neurasthenia, to improve the nutrition of the nervous system. There is no reliable evidence that it has any value. DOSAGE: 0.25 Gm. or 4 grains (U.S.P.), in solution. _Elixir Calcii et Sodii Glycerophosphatum (Elix. Calc. et Sod. Glycerophos.), Elixir of Calcium and Sodium Glycerophosphates, N.F._ (Elixir Glycerophosphatum N.F. III).--Solution of sodium glycerophosphate (2.5%), calcium glycerophosphate (0.875%), phosphoric acid (0.8%), in glycerin, aromatic elixir and distilled water. Absolute alcohol content about 7 per cent. USES: An irrational and inefficient "tonic" mixture. DOSAGE: 4 Cc. or 1 fluidrachm (N.F.). =Calcii Hypophosphis (Calc. Hypophos.), Calcium Hypophosphite, U.S.P.=--Ca(PH{2}O{2}){2}. Colorless crystals or white powder, odorless and having a nauseous, bitter taste. Freely soluble in water (1:6.5) and insoluble in alcohol. ACTION AND USES: The hypophosphites were introduced as of special value in tuberculosis; later they were used as general reconstructive tonics, but there is no experimental or reliable clinical evidence that the hypophosphite radical has any value as such. Calcium hypophosphite must be regarded merely as a means of administering calcium. DOSAGE: 0.5 Gm. or 8 grains (U.S.P.) in syrups. _Elixir Calcii Hypophosphitis (Elix. Calc. Hypophos.), Elixir of Calcium Hypophosphite, N.F._--Calcium hypophosphite (3.5%) in aromatic elixir. Absolute alcohol content about 20 per cent. DOSAGE: 8 Cc. or 2 fluidrachms (N.F.). _Elixir Hypophosphitum (Elix. Hypophos.), Elixir of Hypophosphites, N.F._--Calcium hypophosphite (5.25%), sodium hypophosphite and potassium hypophosphite (each 1.75%) in water, glycerin, compound spirit of cardamom and aromatic elixir. Absolute alcohol content about 12 per cent. DOSAGE: 8 Cc. or 2 fluidrachms (N.F.). _Elixir Hypophosphitum et Ferri._--See under =Ferri Hypophosphis=. _Liquor Hypophosphitum (Liq. Hypophos.), Solution of Hypophosphites, N.F._--Calcium hypophosphite (3.5%), sodium hypophosphite (2%) and potassium hypophosphite (1.75%) in water. DOSAGE: 4 Cc. or 1 fluidrachm (N.F.).
