Polystyrene sulfonate

From WikiMD's Wellness Encyclopedia

(Redirected from Resonium A)

Polystyrene sulfonate is a type of polymer used in medicine to treat hyperkalemia, a condition characterized by high levels of potassium in the blood. It is also known by its brand names, such as Kayexalate, Kionex, and SPS.

Mechanism of Action[edit | edit source]

Polystyrene sulfonate works by exchanging its sodium ions for potassium ions in the gastrointestinal tract, particularly in the large intestine. This exchange process helps to lower the levels of potassium in the body.

Uses[edit | edit source]

Polystyrene sulfonate is primarily used to treat hyperkalemia. It may also be used in patients with chronic kidney disease or those who are on certain medications that can increase potassium levels.

Side Effects[edit | edit source]

Common side effects of polystyrene sulfonate include nausea, vomiting, and constipation. In rare cases, it can cause serious intestinal complications such as intestinal obstruction or colonic necrosis.

Precautions[edit | edit source]

Patients with a history of bowel obstruction, hypokalemia (low potassium levels), or congestive heart failure should use polystyrene sulfonate with caution. It should also be used with caution in patients who are on a low sodium diet.

Interactions[edit | edit source]

Polystyrene sulfonate can interact with certain medications, including lithium and thyroxine. It can also decrease the absorption of other medications taken by mouth.
