Antidotes are substances that can counteract a poison or the effects of a toxin. They work through various mechanisms, including binding to the poison, preventing its absorption, blocking its action at its target site, or accelerating its elimination from the body. The development of an antidote is highly specific to the particular poison it is designed to treat.

There are several categories of antidotes. Some, like chelating agents, bind to heavy metals such as lead or mercury, forming complexes that can be excreted by the body. Others, like naloxone, are receptor antagonists that block the effects of opioids, reversing overdose symptoms. Activated charcoal is another common agent, not strictly an antidote, but used to adsorb poisons in the gastrointestinal tract, preventing their absorption.

The administration of an antidote is typically part of a broader treatment strategy for poisoning, which may also include supportive care to maintain vital functions. The effectiveness of an antidote depends on various factors, including the type and dose of the poison, the time elapsed since exposure, and the patient's overall health. Prompt medical attention is crucial in cases of suspected poisoning, as early intervention often leads to better outcomes. Research continues to develop new and more effective antidotes for a range of toxins.
