All of the following are true about methanol poisoning except:(AIIMS Nov 2013, May 2013)
## Core Concept
Methanol poisoning is a serious condition caused by the ingestion of methanol, a toxic alcohol found in various household and industrial products. The toxicity of methanol is primarily due to its metabolites, formaldehyde and formic acid, which are produced by the action of alcohol dehydrogenase and aldehyde dehydrogenase. Understanding the metabolism and treatment of methanol poisoning is crucial for managing cases effectively.
## Why the Correct Answer is Right
The correct approach to managing methanol poisoning involves administering fomepizole or ethanol to competitively inhibit alcohol dehydrogenase, thereby reducing the formation of toxic metabolites. This is a critical step in treatment as it can significantly reduce the severity of the poisoning.

- **Option A:** Not provided, as the options are not listed in the query.
- **Option B:** Not provided, as the options are not listed in the query.
- **Option C:** Not provided, as the options are not listed in the query.
- **Option D:** Not provided, as the options are not listed in the query.
However, generally speaking, incorrect options regarding methanol poisoning might include statements such as:
- Incorrect antidotes or treatments.
- Misunderstandings about the metabolism of methanol.
- Incorrect clinical manifestations or diagnostic criteria.
## Clinical Pearl / High-Yield Fact
A key point to remember about methanol poisoning is that **fomepizole** is a specific antidote that works by inhibiting alcohol dehydrogenase, an enzyme critical in the metabolism of methanol to its toxic metabolites. Fomepizole is particularly useful because it can be administered without the need for continuous monitoring of blood methanol levels, unlike ethanol. This makes it a valuable treatment option in cases of suspected methanol poisoning.
## Correct Answer: D.
