Which of the following is an antidote for ethylene glycol poisoning?

Fomepizole is the appropriate antidote for ethylene glycol poisoning as it acts as an alcohol dehydrogenase inhibitor. In cases of ethylene glycol ingestion, the body metabolizes this compound into toxic metabolites, namely glycolic acid and oxalic acid, which lead to metabolic acidosis and renal failure. Fomepizole prevents the conversion of ethylene glycol into these harmful metabolites by blocking the enzyme responsible for this process. By inhibiting alcohol dehydrogenase, fomepizole effectively reduces the production of toxic metabolites, helping to safeguard the kidneys and mitigate the associated metabolic derangements.

Furthermore, it is essential to note that timely administration of fomepizole is crucial in addressing the poisoning and is typically preferred over alternative treatments due to its efficacy and lower risk of side effects compared to other interventions that may require more intensive monitoring or have additional complications.
