Yellowish or pinkish white powder or translucent scales, odorless and having a slightly bitter, astringent taste. Freely soluble in water (1:4) and nearly insoluble in alcohol.
Action and Uses: Manganese salts have been tried as hematinic tonics, but are of very doubtful value. The choice among the various salts is a matter of convenience. The soluble citrate is typical of the soluble manganese salts, the dioxide of the insoluble.
Dosage: 0.2 Gm. or 3 grains (N.F.).
Mangani Dioxidum Praecipitatum (Mangan. Diox. Praec.), Precipitated Manganese Dioxide, U.S.P.—Chiefly MnO2.
Heavy, odorless, tasteless black powder. Insoluble in water or alcohol.
Action and Uses: See Mangani Citras Solubilis.
Dosage: 0.25 Gm. or 4 grains (U.S.P.).
Mangani Glycerophosphas Solubilis (Mangan. Glycerophos. Sol.), Soluble Manganese Glycerophosphate, N.F. (Soluble Manganous Glycerinophosphate).—A mixture of manganese glycerophosphate and citric acid.
Yellowish or pinkish white, odorless powder, with an acid taste. Freely soluble in water (1:4); alcohol dissolves the citric acid and leaves a residue which is nearly insoluble in water.
Action and Uses: As a manganese compound it has no material advantage over other manganese salts. For a discussion of glycerophosphates, see Sodii Glycerophosphas.
