USES: It is very improbable that this complex mixture has any advantage over a simple bromide. DOSAGE: 4 Cc. or 1 fluidrachm (N.F.). =*Potassii Carbonas (Pot. Carb.), Potassium Carbonate, U.S.P.=--K{2}CO{3}. (A hydrated form is sold as salt of tartar). White, odorless, deliquescent granular powder with a strongly alkaline taste. Very soluble in water (1:0.9), but insoluble in alcohol. ACTION AND USES: Strongly alkaline and caustic; very dilute solutions sometimes used as antacid. DOSAGE: 1 Gm. or 15 grains (U.S.P.). =*Potassii Chloras (Pot. Chloras), Potassium Chlorate, U.S.P.=--KClO{3}. Colorless, lustrous crystals or white, granular powder, odorless and having a saline taste. Soluble in water (1:11.5) and almost insoluble in alcohol. ACTION AND USES: Used as mouthwash and gargles in stomatitis, etc. Large doses are actively poisonous, causing disintegration of the blood corpuscles. Has been used in the form of gargle and troches for sore throat (swallowing the latter may be dangerous). DOSAGE: 0.25 Gm. or 4 grains (U.S.P.). _Trochisci Potassii Chloratis (Troch. Pot. Chlorat.), Troches of Potassium Chlorate, U.S.P._--Each troche contains potassium chlorate (0.15 Gm. or 2-1/2 grains) with sugar and tragacanth. =Potassii Chloridum (Pot. Chlorid.), Potassium Chloride, N.F.=--KCl. Colorless crystals or white powder, odorless and having a saline taste. Freely soluble in water (1:2.8) and insoluble in alcohol. ACTION AND USES: Has been recommended for use as table salt in place of sodium chloride, in cases in which the absorption of salt was thought to be undesirable. Its value is not established. =*Potassii Citras (Pot. Cit.), Potassium Citrate, U.S.P.= Transparent crystals or white, granular powder; odorless and having a cooling saline taste. Very soluble in water (1:0.6) and almost insoluble in alcohol. ACTION AND USES: Systemic alkali and diuretic like potassium acetate, but more laxative. DOSAGE: 1 Gm. or 15 grains (U.S.P.). _*Potassii Citras Effervescens (Pot. Cit. Eff.), Effervescent Potassium Citrate, U.S.P._--An effervescent mixture representing potassium citrate (20%), sodium citrate (27.55%) and sodium tartrate (38.7%). DOSAGE: 4 Gm. or 1 drachm (U.S.P.). _Liquor Potassii Citratis (Liq. Pot. Cit.), Solution of Potassium Citrate, U.S.P._--Potassium citrate (8%) in water. DOSAGE: 15 Cc. or 4 fluidrachms (U.S.P.). =*Potassii et Sodii Tartras (Pot. et Sod. Tart.), Potassium and Sodium Tartrate, U.S.P.= (Rochelle Salt).
