Differences in iron chelation therapy posology induce disappointing leads to neurodegenerative illnesses at reduced doses, but lifesaving outcomes in thalassemia significant (TM) when employing larger doses. Specifically, the transformation of TM from the lethal into a Serious illness is achieved working with productive doses of oral deferiprone (L1), which improved compliance and cleared surplus poisonous iron from the heart linked to enhanced mortality in TM.
