Who gets antidotes? choosing the chosen fewAn antidote is a substance that can counteract a form of poisoning. Antidotes for anticoagulants are sometimes referred to as reversal agents. The antidotes for some particular toxins are manufactured by injecting the toxin into an animal in small doses and extracting the resulting antibodies from the host animals' blood. This results in an antivenom that can be used to counteract venom produced by certain species of snakes , spiders , and other venomous animals. Some animal venoms, especially those produced by arthropods such as certain spiders , scorpions , and bees are only potentially lethal when they provoke allergic reactions and induce anaphylactic shock ; as such, there is no "antidote" for these venoms; however anaphylactic shock can be treated e. Some other toxins have no known antidote.

Isoniazid poisoning, although the toxicant is unchanged and may still be active. By blocking receptors responsible for the toxic effect : The physiologic effect induced by a toxin is prevented by an antidote. Are you sure you want to Yes No. Manal Goud.
Antidotes to coumarins, methotrexate and thyroxine; toxins that work via metabolic processes? Nature Communications. Expert consensus guidelines for stocking of antidotes in hospitals that provide emergency care. The use of antidotes in mixed overdoses which represent the majority of cases presenting to hospital greatly increases the risks of adverse consequences.
Poisonings are a common problem. In , over 2 million exposures were reported to American poison information centres alone. The majority of poisoning exposures can be treated without major therapeutic intervention. If therapy is indicated, it is usually in the form of gastrointestinal decontamination with activated charcoal, to prevent absorption of the toxin and the subsequent toxicity that may occur. In a limited number of cases, more aggressive life-support measures may be necessary to treat the adverse effects of poisons. Occasionally, that intervention may include the use of pharmacological antagonists, more commonly referred to as antidotes. According to the American Association of Poison Control Centers, the most commonly used antidotes are acetylcysteine, naloxone, atropine, deferoxamine desferrioxamine and antivenins.
