There are plenty of variations in chelation therapy among individuals such as the fee of RBC transfusions, level of iron overload and organ distribution, and pharmacologic and toxicological areas associated with Each and every on the chelating drugs and in addition in the overall chelation therapy end result. The therapeutic responses also are connected to personal profile variations inside the absorption, distribution, metabolism, elimination and toxicity (ADMET) on the drugs [87,147].
