Description Sodium polystyrene sulfonate is a medication used to treat abnormally high potassium levels. It may be taken orally or by rectum, as an enema, and functions as a potassium-binding resin in the intestines. It is also an effective topical microbicide and spermicide, inhibiting the genital transfection of, among others, HIV. [Wikipedia]

Indication Used to treat abnormally high potassium levels.
Pharmacology Polystyrene sulfonate affects the exchange of sodium and potassium in the body. Polystyrene sulfonate is used to treat high levels of potassium in the blood, also called hyperkalemia. It is a potassium-binding ion-exchange resin that can be administered orally (25 grams in 20% sorbitol) or rectally (50 grams in 20% sorbitol).
Mechanism of Action Polystyrene sulfonate, which is not absorbed, binds excess potassium, carrying it out of the body.
Absorption Not absorbed following oral administration.
Toxicity Overdose symptoms may include confusion, irritability, trouble thinking or concentrating, muscle weakness, or trouble breathing.
