_Liquor Potassae Chlorinatae (Liq. Pot. Chlorinat.), Solution of Chlorinated Potassa, N.F._ (Liquor Potassae Chlorate, Javelle Water).--Potassium carbonate (5.8%), chlorinated lime (8%) and water. ACTION AND USES: Same as those of Liquor Sodae Chlorinatae, which see under =Soda Chlorinata=. =Potassa Sulphurata (Pot. Sulphurat.), Sulphurated Potassa, U.S.P.= (Liver of Sulphur).--Chiefly potassium polysulphides and potassium thiosulphate. Irregular pieces, at first liver-brown, later greenish-yellow to gray, with a strong hydrogen sulphide odor and a bitter, acrid, alkaline taste. Very soluble in water; alcohol dissolves only the sulphides. Incompatible with acids and the salts of the heavy metals. ACTION AND USES: Employed as a parasiticide and to stimulate and soften the skin in chronic cutaneous diseases. =*Potassii Acetas (Pot. Acet.), Potassium Acetate, U.S.P.=--KCH{3}COO. White, odorless or nearly odorless powder or crystalline masses with a warming, saline taste. Freely soluble in water (1:0.5) and in alcohol (1:2.9). ACTION AND USES: Systemic alkali and diuretic, practically equivalent to sodium acetate. It can easily be administered in water and milk, so that there appears to be little excuse for the alcoholic elixirs. DOSAGE: 1 Gm. or 15 grains (U.S.P.). _Elixir Potassii Acetatis (Elix. Pot. Acet.), Elixir of Potassium Acetate, N.F._--Potassium acetate (8.5%), and aromatic elixir. Absolute alcohol content about 20 per cent. DOSAGE: 15 Cc. or 4 fluidrachms (N.F.). _Elixir Potassii Acetatis et Juniperi (Elix. Pot. Acet. et Junip.), Elixir of Potassium Acetate and Juniper, N.F._--Potassium acetate (8.5%), fluidextract of juniper (12.5%) and aromatic elixir. Absolute alcohol content about 23 per cent. DOSAGE: 15 Cc. or 4 fluidrachms (N.F.). =Potassii Arsenas, Potassium Arsenate.= _Liquor Arsenicalis Clemens (Liq. Ars. Clemens), Clemens' Solution of Arsenic, N.F._ (Liquor Potassi Arsenatis et Bromidi, N.F. III, Solution of Potassium Arsenate and Bromides).--Contains potassium arsenate corresponding to about 1 per cent. of arsenic trioxide, As{2}O{3}. USES: A superfluous arsenic solution. DOSAGE: 0.2 Cc. or 3 minims (N.F.). =Potassii Arsenis, Potassium Arsenite.= _*Liquor Potassii Arsenitis (Liq. Pot. Arsen.), Solution of Potassium Arsenite, U.S.P._ (Fowler's Solution, Liquor Arsenicalis, Liquor Arsenicalis Fowleri, P.I.).--Arsenic trioxide (1%) and potassium bicarbonate (2%) in compound tincture of lavender and water. Contains potassium arsenite corresponding to 1 per cent. of As{2}O{3}. USES: The most frequently used inorganic arsenical preparation. It has an alkaline reaction and therefore tends to precipitate alkaloids. DOSAGE: 0.2 Cc. or 3 minims (U.S.P.). =*Potassii Bicarbonas (Pot. Bicarb.), Potassium Bicarbonate, U.S.P.=--KHCO{3}.
