Final answer:
It is true that there is no specific antidote for mustard poisoning, and prevention is key. Treatments for nerve agents, such as anticholinergics and oximes, do not apply to mustard agents. Supportive care remains the main treatment for mustard agent exposure.
Step-by-step explanation:
It is true that there is no specific antidote treatment for mustard poisoning. Mustard agents, unlike nerve agents, do not have a dedicated antidote. For nerve agent poisoning, the standard treatment involves an anticholinergic to manage symptoms and an oxime as an antidote, where the oxime works by displacing phosphate molecules from the active site of cholinesterase enzymes. However, similar treatments do not exist for mustard agents, which damage DNA and cells in a different manner.
Prevention is the primary strategy against mustard agent poisoning, with decontamination and supportive care as the mainstay of treatment. In cases of acute arsenic poisoning, which differs from mustard agents, the focus is on treating dehydration and using chelating agents such as dimercaptosuccinic acid (DMSA) or dimercaptopropane sulfonate (DMPS), while dimercaprol (BAL) is not recommended.
