=Mangani Citras Solubilis (Mangan. Cit. Sol.), Soluble Manganese Citrate, N.F.= (Manganese and Sodium Citrate).

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 MnO{2}.

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=.

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

=Mangani Hypophosphis (Mangan. Hypophos.), Manganese Hypophosphite, N.F.=--Mn(H{2}PO{2}){2} + H{2}O.

Pink, odorless, nearly tasteless powder. Freely soluble in water and insoluble in alcohol.

ACTION AND USES: As a manganese compound, has no material advantage over other manganese salts. For a discussion of hypophosphites, see =Calcii Hypophosphis=.

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

=Mangani Sulphas (Mangan. Sulph.), Manganese Sulphate, N.F.=--MnSO{4} (about 65%).

Pale rose-colored, translucent, odorless crystals, with a slightly bitter taste, slightly efflorescent in moist air. Freely soluble in water (1:1) and insoluble in alcohol.

ACTION AND USES: Without material advantage over other manganese salts.

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

DOSAGE: 8 Cc. or 2 fluidrachms (N.F.).

=Ma.s.sAE, Ma.s.sES.=--Soft solid preparations of such consistency that they can readily be made into pills. For the various ma.s.ses, see under the names of the respective drugs.

=Mastiche (Mastic.), Mastic, N.F.=--A resin.

Completely soluble in ether and almost completely soluble in alcohol.

_Fluidextractum Matico (Fldext. Matic.), Fluidextract of Matico, N.F._--Matico (100%). Absolute alcohol content about 60 per cent.

DOSAGE: 4 Cc. or 1 fluidrachm (N.F.).

=Matricaria (Matricar.), Matricaria, U.S.P.= (German Chamomile, Wild Chamomile).--Flower heads.
