DESCRIPTION Sodium Polystyrene Sulfonate Suspension USP (SPS ® Suspension) can be administered orally or in an enema. It is a cherry-flavored suspension containing 15 grams of cation-exchange resin (Sodium Polystyrene Sulfonate USP); 21.5 mL of Sorbitol Solution USP (equivalent to approximately 20 grams of Sorbitol) ; 0.18 mL (0.3%) of Alcohol per 60 mL of suspension.
Overview
DESCRIPTION Sodium Polystyrene Sulfonate Suspension USP (SPS ® Suspension) can be administered orally or in an enema. It is a cherry-flavored suspension containing 15 grams of cation-exchange resin (Sodium Polystyrene Sulfonate USP); 21.5 mL of Sorbitol Solution USP (equivalent to approximately 20 grams of Sorbitol) ; 0.18 mL (0.3%) of Alcohol per 60 mL of suspension.
Uses
INDICATION AND USAGE SPS ® Suspension is indicated for the treatment of hyperkalemia.
Dosage
DOSAGE AND ADMINISTRATION Administer sodium polystyrene sulfonate suspension at least 3 hours before or 3 hours after other oral medications. Patients with gastroparesis may require a 6 hour separation (see WARNINGS and PRECAUTIONS, Drug Interactions ). The average daily adult dose is 15 g (60 mL) to 60 g (240 mL) of suspension. This is best provided by administering 15 g (60 mL) of SPS ® Suspension one to four times daily. Each 60 mL of SPS ® Suspension contains 1500 mg (65 mEq) of sodium. Since the in-vivo efficiency of sodium-potassium exchange resins is approximately 33%, about one-third of the resin's actual sodium content is being delivered to the body.
Side Effects
ADVERSE REACTIONS SPS ® Suspension may cause some degree of gastric irritation. Anorexia, nausea, vomiting, and constipation may occur especially if high doses are given. Also, hypokalemia, hypocalcemia, hypomagnesemia and significant sodium retention, and their related clinical manifestations, may occur (See WARNINGS ). Occasionally diarrhea develops. Large doses in elderly individuals may cause fecal impaction (See PRECAUTIONS ). Rare instances of intestinal necrosis have been reported. Intestinal obstruction due to concretions of aluminum hydroxide, when used in combination with sodium polystyrene sulfonate, has been reported.
Interactions
Drug Interactions General Interactions No formal drug interaction studies have been conducted in humans. Sodium polystyrene sulfonate suspension has the potential to bind other drugs. In in-vitro binding studies, sodium polystyrene sulfonate was shown to significantly bind the oral medications (n=6) that were tested. Decreased absorption of lithium and thyroxine have also been reported with co-administration of sodium polystyrene sulfonate. Binding of sodium polystyrene sulfonate suspension to other oral medications could cause decreased gastrointestinal absorption and loss of efficacy when taken close to the time sodium polystyrene sulfonate suspension is administered. Administer sodium polystyrene sulfonate suspension at least 3 hours before or 3 hours after other oral medications.
Warnings
WARNINGS Intestinal Necrosis Cases of intestinal necrosis, which may be fatal, and other serious gastrointestinal adverse events (bleeding, ischemic colitis, perforation) have been reported in association with sodium polystyrene sulfonate use. The majority of these cases reported the concomitant use of sorbitol. Risk factors for gastrointestinal adverse events were present in many of the cases including prematurity, history of intestinal disease or surgery, hypovolemia, and renal insufficiency and failure. Concomitant administration of additional sorbitol is not recommended (see PRECAUTIONS, Drug Interactions ). • Use only in patients who have normal bowel function. Avoid use in patients who have not had a bowel movement post-surgery. CONTRAINDICATIONS SPS ® Suspension is contraindicated in the following conditions: patients with hypokalemia, patients with a history of hypersensitivity to polystyrene sulfonate resins, obstructive bowel disease, oral or rectal administration in neonates (See PRECAUTIONS ).
Pregnancy
Pregnancy Category C Animal reproduction studies have not been conducted with sodium polystyrene sulfonate. It is also not known whether sodium polystyrene sulfonate can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Sodium polystyrene sulfonate should be given to a pregnant woman only if clearly needed.
