定義
ChEBI: The anhydrous form of the tripotassium salt of citric acid.
調(diào)製方法
Potassium citrate is produced by adding potassium bicarbonate or potassium carbonate to a solution of citric acid until effervescence ceases, filtering the solution and evaporating to granulation.
工業(yè)用途
Potassium citrate is used in the United Kingdom as an over-the-counter drug for the relief from discomfort
experienced in mild urinary-tract infections by increasing the urinary pH. It should be not given to men if
they experience pain in the kidney area (risk of kidney stones) or if blood or pus is present in the urine. Also,
patients with raised blood pressure or diabetes should avoid taking potassium citrate without consultation
with their general practitioner (GP). Caution is generally advised to patients with renal impairment, cardiac
problems and the elderly [3a].
安全性プロファイル
Poison by intravenous
route. When heated to decomposition it
emits toxic fumes of K2O.
予防処置
Potassium citrate is usually administered by mouth in dilute aqueous solution. This is because of its somewhat caustic effect on the stomach lining, and the potential for other mild health hazards.
In states where non-prescription potassium citrate is legal, the maximum allowable over-the-counter (OTC) dose for elemental potassium is regulated by the FDA to be no more than 100 mg (approximately 3 % of the daily allowance ) . Pure potassium citrate contains 38.28 % potassium.
