These could involve the use of new chelating drugs and best chelation therapy protocols for expanding iron excretion, chosen meal plans and therapies for inhibiting iron absorption and the use of modulators for regulatory molecules involved with erythropoiesis and iron metabolism like activators of HbF production, proteins affecting iron transport, utilisation and storage, in addition to combos of these kinds of treatment plans.
Frequently, drugs bind non-especially to albumin within the plasma. In addition, one drug, digoxin, has a tendency to bind non-specially to skeletal muscle mass, when, in actual fact, its desired actions manifest in the center.
