Disadvantages of chelation therapy include things like drug toxicity in certain sufferers and likewise the huge use of suboptimal chelation protocols, resulting in ineffective therapies. Drug metabolic results, and interactions with other metals, drugs and dietary molecules also affected iron chelation therapy. Drug range as well as identification of effective or ideal dose protocols are important for constructive therapeutic results in the usage of chelating drugs in TM and other iron-loaded and non-iron-loaded disorders, along with standard iron toxicity.
