_Extractum Stramonii (Ext. Stramon.), Extract of Stramonium, U.S.P._--Two forms: Pilular extract of stramonium and powdered extract of stramonium. One Gm. of extract represents about 4 Gm. of stramonium and yields about 1 per cent. of alkaloids. DOSAGE: 0.01 Gm. or 1/6 grain (U.S.P.). _Fluidextractum Stramonii (Fldext. Stramon.), Fluidextract of Stramonium, N.F._--Stramonium (100%), yielding about 0.25 per cent. of alkaloids. Absolute alcohol content about 55 per cent. DOSAGE: 0.05 Cc. or 1 minim (N.F.). _Tinctura Stramonii (Tr. Stramon.), Tincture of Stramonium, U.S.P._--Stramonium (10%), yielding about 0.025 per cent. of stramonium alkaloids. Absolute alcohol content about 40 per cent. DOSAGE: 0.5 Cc. or 8 minims (U.S.P.). _Unguentum Stramonii (Ung. Stramon.), Stramonium Ointment, U.S.P._--Pilular extract of stramonium (10%), diluted alcohol, hydrous wool fat and benzoinated lard. =Strontii Bromidum (Stront. Brom.), Strontium Bromide, U.S.P.=--SrBr{2} + 6H{2}O. Colorless, odorless crystals, having a bitter, saline taste. Very soluble in water (1:0.35); soluble in alcohol. ACTION AND USES: Similar to those of sodium bromide over which it has no definite advantage. DOSAGE: 1 Gm. or 15 grains (U.S.P.) =Strontii Carbonas (Stront. Carb.), Strontium Carbonate, N.F.=--SrCO{3}. White, odorless, tasteless powder. Insoluble in water and in alcohol. Decomposed by acids. ACTION AND USES: Of use only in the making of soluble salts of strontium =Strontii Iodidum (Stront. Iod.), Strontium Iodide, U.S.P.=--SrI{2} + 6H{2}O. Colorless crystals or white powder or crystalline crusts, turning yellow on exposure to light; odorless, deliquescent and having a bitter saline taste. Very soluble in water (1:0.2); somewhat less soluble in alcohol. ACTION AND USES: Similar to, but without definite advantage over potassium iodide. DOSAGE: 0.3 Gm. or 5 grains (U.S.P.) =Strontii Salicylas (Stront. Salicyl.), Strontium Salicylate, U.S.P.=--Sr(C{6}H{4}.OH.COO){2} + 2H{2}O. White, odorless powder, having a somewhat sweet, saline taste. Soluble in water (1:19) and in alcohol (1:61). ACTION AND USES: Identical with those of sodium salicylate, over which it has no advantage. DOSAGE: 1 Gm. or 15 grains (U.S.P.) =*Strophanthinum (Strophanthin.), Strophanthin, U.S.P.=--A glucoside or mixture of glucosides obtained from strophanthus. White or yellowish powder. Very soluble in water and in diluted alcohol. ACTION AND USES: Like those of digitalis. Strophanthin acts more rapidly and is excreted sooner, but its absorption from the alimentary canal is so variable that its administration by mouth is inadvisable. DOSAGE: Daily by mouth, 0.001 Gm. or 1/60 grain (U.S.P.); intravenous, 0.00075 Gm. or 1/80 grain (U.S.P.). Caution should be used if patient has been taking digitalis =*Strophanthus (Strophanth.), Strophanthus, U.S.P.=--Ripe seeds.
