Hyperkalemia is an elevated level of potassium (K +) in the blood. [1] Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels above 5.5 mmol/L defined as hyperkalemia. [3] [4] Typically hyperkalemia does not cause symptoms. [1] Occasionally when severe it can cause palpitations, muscle pain, muscle weakness, or ...
Potassium binders are medications that bind potassium ions in the gastrointestinal tract, thereby preventing its intestinal absorption. This category formerly consisted solely of polystyrene sulfonate, a polyanionic resin attached to a cation, administered either orally or by retention enema to patients who are at risk of developing hyperkalaemia (abnormal high serum potassium levels).
Mild hyperkalemia without symptoms can be treated with a loop diuretic and sodium polystyrene sulfonate, while a temporizing agent such as rapid acting insulin (in conjunction with glucose) and an agent to stabilize cardiac membranes such as calcium carbonate may be given in cases of severe hyperkalemia. [18] Concerning symptoms related to ...
Polystyrene sulfonate is usually supplied in either the sodium or calcium form. It is used as a potassium binder in acute and chronic kidney disease for people with hyperkalemia (an abnormally high blood serum potassium level). [ 3 ]
Several approaches are used to treat hyperkalemia. [12] Other approved potassium binders in the United States include patiromer and sodium polystyrene sulfonate. [13] Hyperkalemia, particularly if severe, is a marker for an increased risk of death. [14] However, there is disagreement regarding whether a modestly elevated levels directly causes ...
Hyperkalemia is the most serious adverse reaction to potassium. Hyperkalemia occurs when potassium builds up faster than the kidneys can remove it. It is most common in individuals with renal failure. Symptoms of hyperkalemia may include tingling of the hands and feet, muscular weakness, and temporary paralysis.
Hypoaldosteronism causes low sodium (hyponatremia), high potassium (hyperkalemia), and metabolic acidosis, a condition in which the body produces excess acid.These conditions are responsible for the symptoms of hypoaldosteronism, which include muscle weakness, nausea, palpitations, irregular heartbeat, and abnormal blood pressure.
A common group of medication that utilizes a combination of polystyrene and sulfonate functional groups are polystyrene sulfonates. [3] This medication is primarily used to treat hyperkalemia, a condition that results from an increased blood potassium level. [3] FDA approved equivalents of polystyrene sulfonates are KIONEX, KALEXATE, and SPS ...
