翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Potassium binder ： ウィキペディア英語版 Potassium binder Potassium binders are medications that bind potassium ions in the gastrointestinal tract, thereby preventing its intestinal absorption. They consist of polystyrene sulfonate resins attached to a cation and are administered either orally or by retention enema to patients who are at risk of developing hyperkalaemia (abnormal high serum potassium levels). Increased serum potassium levels are a condition likely to occur in patients suffering from chronic kidney disease in advanced stages. ==Clinical use== Potassium, the most abundant intracellular cation, is essential for life. An adequate gradient of potassium across the cell membrane is necessary in order to enable excitability of cell membranes. This is particularly important for nerve and muscle function. In humans, mainly the kidneys are responsible for the regulation of serum potassium levels by excreting excess potassium via the urine. As kidney failure progresses, with a consequent decline of excretory function, potassium is likely to accumulate with probable harmful effects on the cellular membrane potential and cardiac arrhythmias as the primary symptom. If the physiological potassium blood level of between 3.8 mmol/L and 5.2 mmol/L is exceeded, hyperkalaemia is diagnosed.〔Hagemann, O., Normal Serum Potassium Levels, URL: http://www.laborlexikon.de/Lexikon/Infoframe/k/Kalium_Serum.htm; Retrieved 21 January 2010.〕 The mainstay of the treatment for chronic kidney disease patients is potassium removal through the dialysis procedure. However, dietary restrictions and pharmaceutical therapy with potassium binders are important complementary treatment options. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Potassium binder」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
