_Elixir Lithii Bromidi (Elix. Lith. Brom.), Elixir of Lithium Bromide, N.F._--Lithium bromide (8.5%) in syrup, water and aromatic elixir. Absolute alcohol content about 7 per cent. DOSAGE: 8 Cc. or 2 fluidrachms (N.F.). =Lithii Carbonas (Lith. Carb.), Lithium Carbonate, U.S.P.=--Li{2}CO{3}. Light white, odorless powder with an alkaline taste. Soluble in water (1:78); almost insoluble in alcohol. ACTION AND USES: Used in the same way as sodium carbonate; without advantage over the latter. Lithium was formerly given to promote the elimination of urates because it was supposed to have special urate-solvent properties, but under the conditions existing in the body these properties do not come into play. DOSAGE: 0.5 Gm. or 8 grains (U.S.P.). =Lithii Citras (Lith. Cit.), Lithium Citrate, U.S.P.= White, odorless powder or granules, with a cooling, faintly alkaline taste. Freely soluble in water (1:1.4), very slightly soluble in alcohol. ACTION AND USES: Used like citrates of sodium or potassium, over which it has no advantage. For the supposed urate-solvent properties of lithium, see Lithii Carbonas. DOSAGE: 0.5 Gm. or 8 grains (U.S.P.). _Elixir Lithii Citratis (Elix. Lith. Cit.), Elixir of Lithium Citrate, N.F._--Lithium citrate (8.5%), in aromatic elixir. Absolute alcohol content about 21 per cent. USES: An objectionable alcoholic preparation of lithium. DOSAGE: 8 Cc. or 2 fluidrachms (U.S.P.). _Sal Lithii Citratis Effervescens (Sal. Lith. Cit. Eff.), Effervescent Salt of Lithium Citrate, N.F._--Lithium citrate (5%), sodium bicarbonate (57%), tartaric acid (30%) and citric acid, the three last-named yielding sodium tartrate and sodium citrate. USES: Superfluous, and in view of its small lithium content, misnamed. DOSAGE: 8 Gm. or 2 drachms (N.F.). =Lithii Salicylas (Lith. Salicyl.), Lithium Salicylate, N.F.=-- White or grayish white odorless powder, with a sweetish taste; deliquescent in a moist atmosphere. Very soluble in water or alcohol. ACTION AND USES: As a salicylate, inferior to sodium salicylate. Adequate doses would produce the toxic effects of lithium. For the supposed urate-solvent effects of lithium salts, see =Lithii Carbonas=. DOSAGE: 1 Gm. or 15 grains (N.F.). _Elixir Lithii Salicylatis (Elix. Lith. Salicyl.), Elixir of Lithium Salicylate, N.F._--Lithium salicylate (8.5%) in aromatic elixir. Absolute alcohol content about 21 per cent. USES: An objectionable alcoholic salicylic preparation. DOSAGE: 8 Cc. or 2 fluidrachms (N.F.). =Lobelia (Lobel.), Lobelia, U.S.P.= (Indian Tobacco).--Leaves and flowering tops. ACTION AND USES: Expectorant, nauseant and emetic, resembling nicotine. Has fallen into disuse because of dangerous effects. DOSAGE: 0.15 Gm. or 2-1/2 grains (U.S.P.). _Fluidextractum Lobeliae (Fldext. Lobel.), Fluidextract of Lobelia, U.S.P._--Lobelia (100%). Absolute alcohol content about 40 per cent.
