What is the importance of antidote?
Introduction. Antidotes are agents that negate the effect of a poison or toxin. Antidotes mediate its effect either by preventing the absorption of the toxin, by binding and neutralizing the poison, antagonizing its end-organ effect, or by inhibition of conversion of the toxin to more toxic metabolites.
When should the antidote be administered?
Antidotes. Antidote administration is appropriate when there is a poisoning for which an antidote exists, when the actual or predicted severity of the poisoning warrants its use, when expected benefits of therapy outweigh its associated risk, and when there are no contraindications.
How many types of antidotes are there?
Antidotes developed for treatment of nerve agent intoxication can be divided into two types: prophylaxis, as preexposure administration of antidotes; and post-exposure treatment, consisting of anticholinergic drugs, AChE reactivators, and anticonvulsants.

“Treat the patient, not the toxin” is hence the guiding dictum in clinical toxicology. In a small proportion (<2%) of toxins,1antidotes have been identified. It must be stressed that the expected benefit of the antidote must be determined and weighed against the potential side effects and toxicity of the antidote.
How is activated charcoal used as an antidote?
13. How is activated charcoal used as an antidote? As an antidote, activated charcoal is mainly known both for its use in drug overdoses and chemical poisonings.
