Dosage: 0.2 Gm. or 3 grains (N.F.).

Calamina Praeparata (Calamin. Praep.), Prepared Calamine, N.F. (Lapis Calaminaris).—Native zinc carbonate.

A pink powder. Insoluble in water.

Action and Uses: Protective, similar to zinc oxide, over which it has no therapeutic advantage; has the cosmetic advantage of being slightly pink.

Unguentum Calaminae (Ung. Calamin.), Calamine Ointment, N.F. (Unguentum Zinci Carbonatis Crudi, Unguentum Calaminare, Turner’s Cerate).—Prepared calamine (17%) in ointment.

Calcii Bromidum (Calc. Brom.), Calcium Bromide, U.S.P.—Hydrated calcium bromide (not less than 84 per cent. of CaBr₂).

A white, odorless, deliquescent powder, with a sharp, saline taste. Very soluble in water (1:0.7) and in alcohol (1:1.3). Incompatible with alkali carbonates and phosphates.

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.
