Heavy metal toxicity poses significant health risks to human populations worldwide due to exposure through various environmental sources. While prevention and mitigation efforts primarily focus on reducing exposure, pharmacological interventions play a crucial role in managing acute poisoning and chronic exposure cases. This article explores the pharmacological interventions used in heavy metal toxicity, including chelation therapy, supportive treatments, and emerging therapeutic approaches. Chelation therapy is a cornerstone pharmacological intervention for heavy metal toxicity, particularly in cases of acute poisoning or high-level exposure. Chelating agents are compounds that bind to heavy metals in the bloodstream, forming stable complexes that can be excreted via urine or faeces, thus reducing their toxicity. Ethylenediaminetetraacetic acid (EDTA), dimercaprol (BAL), dimercaptosuccinic acid (DMSA), and dimercaptopropane sulfonate (DMPS) are commonly used chelating agents in clinical practice. EDTA is effective in chelating divalent cations such as lead, cadmium, and mercury, while BAL is primarily used for arsenic, mercury, and lead poisoning. DMSA and DMPS are orally administered chelators with fewer adverse effects than BAL, making them suitable for outpatient treatment of chronic heavy metal exposure, especially in children. In addition to chelation therapy, supportive treatments are essential in managing heavy metal toxicity to alleviate symptoms and prevent complications. Supportive measures may include intravenous fluids to maintain hydration, electrolyte balance, and renal function, as well as symptomatic treatments for gastrointestinal symptoms, neurological manifestations, and organ damage. For example, calcium disodium versenate (CaEDTA) may be administered in combination with supportive treatments in cases of severe lead poisoning to enhance lead excretion and mitigate its neurotoxic effects. Furthermore, specific antidotes such as British Anti-Lewisite (BAL) may be used in cases of arsenic poisoning to counteract its systemic effects. Recent advances in pharmacology and toxicology have led to the exploration of novel therapeutic approaches for heavy metal toxicity. Nanotechnology-based interventions, such as metal-binding nanoparticles and nanocomposites, show promise in enhancing heavy metal chelation efficiency and reducing systemic toxicity. Furthermore, natural products and antioxidants have gained attention for their potential protective effects against heavy metal-induced oxidative stress and tissue damage. Compounds such as N-acetylcysteine (NAC), alpha-lipoic acid (ALA), and curcumin have demonstrated chelating properties and antioxidant activity, offering potential adjunctive therapy in heavy metal toxicity management. Despite the effectiveness of pharmacological interventions, several challenges exist in their implementation and optimization. Limited availability and affordability of chelating agents, especially in low-resource settings, may hinder timely treatment of heavy metal poisoning cases. Moreover, chelation therapy carries the risk of adverse effects, including nephrotoxicity, allergic reactions, and electrolyte imbalances, necessitating careful patient monitoring and dose adjustment. Furthermore, the choice of chelating agent and treatment regimen depends on various factors, including the type of heavy metal, route of exposure, severity of poisoning, and individual patient characteristics. Additionally, the long-term effects of chelation therapy on heavy metal distribution, tissue accumulation, and organ function require further investigation to optimize treatment outcomes and minimize potential risks. Pharmacological interventions play a crucial role in managing heavy metal toxicity, providing effective treatment options for acute poisoning cases and chronic exposure scenarios.
