DRUG CLASS AND MECHANISM: Potassium preparations are used for supplementing potassium in order to treat or prevent low potassium levels in the blood (hypokalemia). Potassium is a major mineral (electrolyte) that is important for the function of every cell in the body. For example, it is important in nerve conduction, muscle contraction, and kidney function. Normal daily dietary intake of potassium is 40-150 mEq. Potassium deficiency occurs when potassium loss exceeds intake. Potassium depletion may be caused by excessive vomiting or diarrhea, diabetic ketoacidosis, diuretics (for example, furosemide [Lasix]), starvation, and rare disorders of the adrenal glands. Potassium deficiency causes weakness, fatigue, heart rhythm problems, paralysis, and kidney dysfunction.
