USES: An antiquated preparation, without the special advantages generally ascribed to it. Iron and acetates are better prescribed separately. DOSAGE: 15 Cc. or 4 fluidrachms (U.S.P.). =Ammonii Benzoas (Ammon. Benz.), Ammonium Benzoate, U.S.P.= A white, odorless or nearly odorless powder, with a bitterish taste. Very soluble in water (1:10) and soluble in alcohol (1:35). Incompatible with acids, fixed alkalies and ferric salts. ACTION AND USES: Resembles sodium benzoate in its action but is more irritant and has no advantage over it. DOSAGE: 1 Gm. or 15 grains (U.S.P.), in solution =Ammonii Bromidum (Ammon. Brom.), Ammonium Bromide, U.S.P.=--NH{4}Br. A white, odorless powder with a pungent saline taste. Incompatible with nitrous ether. ACTION AND USES: Those of the bromides; more irritant than potassium bromide, over which it has no advantage. DOSAGE: 1 Gm. or 15 grains (U.S.P.) in solution. _Elixir Ammonii Bromidi (Elix. Ammon. Brom.), Elixir of Ammonium Bromide, N.F._--Ammonium bromide (8.5%), syrup, distilled water and aromatic elixir. Absolute alcohol content about 5 per cent. DOSAGE: 4 Cc. or 1 fluidrachm. _Elixir Trium Bromidorum (Elix. Tri. Brom.), Elixir of Three Bromides, N.F._--Ammonium bromide, potassium bromide and sodium bromide (each 8%), with cudbear and compound elixir of almond. Absolute alcohol content about 4 per cent. USES: An irrational bromide mixture, as there is no good evidence that the bases influence the bromide action materially. DOSAGE: 4 Cc. or 1 fluidrachm (N.F.). =*Ammonii Carbonas (Ammon. Carb.), Ammonium Carbonate, U.S.P.=--A mixture of ammonium bicarbonate and ammonium carbamate, yielding about 31 per cent. of NH{3}. White, hard, translucent masses, with a strong ammoniacal odor and a sharp, ammoniacal taste. Very soluble in water; alcohol dissolves the carbamate and leaves the bicarbonate. ACTION AND USES: Alkaline and nauseant liquefying expectorant used in cough mixtures; also as reflex "diffusible" stimulant in smelling salts. DOSAGE: 0.3 Gm. or 5 grains (U.S.P.) in solution. _Mistura Pectoralis Stokes (Mist. Pect. Stokes), Stokes' Expectorant, N.F._--Ammonium carbonate (1.75%), fluidextracts of senega and squill (each 3.5%), camphorated tincture of opium (17.5%), water and syrup of tolu. Absolute alcohol content about 10 per cent. USES: Irrational expectorant mixture. DOSAGE: 4 Cc. or 1 fluidrachm (N.F.). _*Spiritus Ammoniae Aromaticus (Sp. Ammon. Arom.), Aromatic Spirit of Ammonia, U.S.P._--Ammonium carbonate (3.4%), ammonia water (9%) and oils of lemon, lavender and myristica in alcohol and distilled water. Absolute alcohol content about 68 per cent. USES: Useful aromatic alkali and carminative in flatulence, colic, etc. DOSAGE: 2 Cc. or 30 minims (U.S.P.). =*Ammonii Chloridum (Ammon. Chlor.), Ammonium Chloride, U.S.P.=--NH{4}Cl.
