Study Notes

Methanol Poisoning Antidote

The antidote for methanol poisoning is ethanol.

Ethanol as an Antidote

Ethanol acts as a competitive inhibitor of the enzyme alcohol dehydrogenase, blocking the conversion of methanol to its toxic metabolites.
Ethanol has a higher affinity for alcohol dehydrogenase than methanol, thereby inhibiting the metabolism of methanol.

Administration of Ethanol

It is important to administer ethanol as an antidote for methanol poisoning to prevent the formation of toxic metabolites, which can cause blindness, seizure, and even death.
Timely administration of ethanol can help reduce the risk of these severe complications.
