KCl

KCl, or potassium chloride, is a chemical compound used primarily to treat or prevent potassium deficiency in patients, particularly those on diuretics or with conditions like renal failure. It is crucial in maintaining normal cellular function, nerve transmission, and muscle contraction, including cardiac function. An important complication of KCl administration is hyperkalemia, which can lead to life-threatening cardiac arrhythmias if not monitored carefully.
