Epitome of the Pharmacopeia of the United States and the National Formulary — Part 37

ACTION AND USES: Similar to but more irritant than sodium bromide, over which it has ordinarily no advantage, although the calcium perhaps increases the sedative action.

DOSAGE: 1 Gm. or 15 grains, preferably administered in aqueous solutions, being too deliquescent for use in powder or cachets.

_Elixir Calcii Bromidi (Elix. Calc. Brom.), Elixir of Calcium Bromide, N.F._--Calcium bromide (8.5%) diluted hydrobromic acid (0.4%), syrup, distilled water and aromatic elixir. Absolute alcohol content about 7 per cent.

=*Calcii Carbonas Praecipitatus (Calc. Carb. Praec.), Precipitated Calcium Carbonate, U.S.P.= (Precipitated Chalk).--CaCO{ 3}.

A fine, white, odorless, tasteless powder. Nearly insoluble in water and insoluble in alcohol. Decomposed by acids with evolution of carbon dioxide.

ACTION AND USES: Chiefly used as a basis for tooth powder. Internally, employed as an antacid in diarrheas, etc.; externally in mixtures with cream or oil, has been used as an application to burns as an antacid and protective.

DOSAGE: 1 Gm. or 15 grains (U.S.P.), as powder or in suspension

=*Calcii Chloridum (Calc. Chlor.), Calcium Chloride, U.S.P.=--Hydrated calcium chloride (not less than 75 per cent. of CaCl{ 2}).

White, hard, deliquescent, odorless masses or granules, with a sharp, saline taste. Very soluble in water (1:0.62), and freely soluble in alcohol (1:10).

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.).
