Generic Name: Deferiprone
Product Name: Ferriprox
Indication of Ferriprox
Ferriprox tablets contain an ingredient called deferiprone. This is used to treat patients with thalassaemia major, because these patients need to undergo blood transfusion, iron is accumulated in the body over time. If the excess iron is not removed, it can cause serious damage to many organs in the body.
Usually a medication called desferrioxamine is used to treat these patients with iron overload. However, if the patients are unable to take desferrioxamine or this has proven ineffective, deferiprone is used.
Action of Ferriprox
Deferiprone binds to the iron in the blood and will be excreted from the body, hence, removing excess iron. Studies have shown that deferiprone can reduce the iron store in the body as well. However, the exact method on how it acts is unknown.
