Specific inhibitor of alcohol dehydrogenase –
**Core Concept**
Alcohol dehydrogenase is an enzyme involved in the metabolism of ethanol, converting it into acetaldehyde. Inhibiting this enzyme can reduce the metabolism of alcohol and potentially mitigate its toxic effects.
**Why the Correct Answer is Right**
The correct answer is a specific inhibitor of alcohol dehydrogenase, which works by binding to the enzyme and preventing it from converting ethanol into acetaldehyde. This can help reduce the accumulation of toxic metabolites and alleviate symptoms associated with excessive alcohol consumption. The specific inhibitor is also known to have therapeutic applications in managing alcohol-related disorders.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a specific inhibitor of alcohol dehydrogenase. Instead, it may be a general inhibitor of various enzymes involved in alcohol metabolism.
**Option B:** This option is incorrect because it is a drug that is used to treat a different medical condition, unrelated to alcohol metabolism.
**Option C:** This option is incorrect because it is a metabolite of ethanol, rather than an inhibitor of alcohol dehydrogenase.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that specific inhibitors of alcohol dehydrogenase can have therapeutic applications in managing alcohol-related disorders, such as reducing the risk of liver damage or mitigating the symptoms of withdrawal.
**Correct Answer:** Fomepizole. Fomepizole is a specific inhibitor of alcohol dehydrogenase, used in the treatment of methanol and ethylene glycol poisoning.
