These polymers are derived from polystyrene by the addition of sulfonate functional groups. Sodium polystyrene sulfonate was approved for medical use in the United States in 1958. [1] A polystyrene sulfonate was developed in the 2000s to treat Clostridioides difficile associated diarrhea under the name Tolevamer, [2] but it was never marketed.
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).
Measures to remove potassium from the body include diuretics such as furosemide, potassium-binders such as polystyrene sulfonate (Kayexalate) and sodium zirconium cyclosilicate, and hemodialysis. [1] Hemodialysis is the most effective method. [3] Hyperkalemia is rare among those who are otherwise healthy. [6]
These methods include polystyrene microspheres, nanoparticles, and solid foams. In the biomedical engineering field, these methods assist researchers in drug delivery, diagnostics, and imaging strategies. [1] [2] A common group of medication that utilizes a combination of polystyrene and sulfonate functional groups are polystyrene sulfonates. [3]

A treatment for hyperkalaemia (elevated blood potassium) uses sorbitol and the ion-exchange resin sodium polystyrene sulfonate (tradename Kayexalate). [17] The resin exchanges sodium ions for potassium ions in the bowel, while sorbitol helps to eliminate it.
The structure of sodium polystyrene sulfonate is shown. When this salt is dissolved in a solvent, the negatively charged side group can adsorb positively charged adsorbates. When this salt is dissolved in a solvent, the negatively charged side group can adsorb positively charged adsorbates.
Polystyrene sulfonate, a cation-exchange resin, is typically supplied with Na + as the counterion. In chemistry , a counterion (sometimes written as " counter ion ", pronounced as such) is the ion that accompanies an ionic species in order to maintain electric neutrality.
