Chelation agents

Class Summary

Deferoxamine is a specific iron chelator. In the presence of ferric iron, deferoxamine forms the complex ferrioxamine, which is excreted by the kidneys. This complex imparts a reddish, vin rosé, color to the urine. Deferoxamine does not bind iron that is present in hemoglobin, hemosiderin, or ferritin. Deferoxamine is a parenteral iron chelator. It is administered IV or IM in the management of acute iron toxicity.

Deferoxamine mesylate (Desferal)

Freely soluble in water. Approximately 8 mg of iron is bound by 100 mg of deferoxamine. Most effective when continuously provided to the circulation by infusion. May be administered either by IM injection or by slow IV infusion. Does not effectively chelate other trace metals of nutritional importance. Provided in vials containing 500 mg or 2 g of lyophilized sterile drug. Add 2 mL or 8 mL of sterile water for injection to each vial, bringing the concentration to 250 mg/mL. For IV use, this may be diluted in 0.9% sterile saline, 5% dextrose solution, or Ringer solution.

Deferasirox (Exjade)

Tab for PO susp. PO iron chelation agent demonstrated to reduce liver iron concentration in adults and children who receive repeated RBC transfusions. Binds iron with high affinity in a 2:1 ratio. Approved to treat chronic iron overload due to multiple blood transfusions. Treatment initiation recommended upon evidence of chronic iron overload (ie, transfusion of about 100 mL/kg packed RBCs [about 20 U for 40-kg person] and serum ferritin level consistently >1000 µg/L).

Class Summary

Polyethylene glycol is used to increase GI transit time, decreasing absorption. It is not absorbed and is excreted entirely through the GI tract.

Polyethylene glycol (GoLYTELY, NuLytely, Colovage, Colyte)

Laxative with strong electrolyte and osmotic effects that has cathartic actions in GI tract.
