Drug used for cocaine withdrawal symptoms is-
**Core Concept**
The management of cocaine withdrawal involves pharmacological interventions to alleviate symptoms and reduce cravings. Cocaine withdrawal typically presents with symptoms such as irritability, anxiety, fatigue, and intense cravings for the drug.
**Why the Correct Answer is Right**
The correct answer is **B. Disulfiram**. Disulfiram acts by inhibiting the enzyme acetaldehyde dehydrogenase, which is involved in the metabolism of ethanol. Although it's primarily used for treating chronic alcoholism, disulfiram's mechanism of action can be utilized to deter individuals from consuming cocaine by inducing unpleasant symptoms when cocaine is used. This is achieved through the accumulation of toxic metabolites, such as ethylamine and benzoyl-ecgonine, which are produced when cocaine is metabolized.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because methadone is primarily used for opioid detoxification and maintenance therapy, not cocaine withdrawal.
**Option C:** This option is incorrect because naltrexone is an opioid antagonist used to treat opioid dependence and alcohol dependence, but it's not the primary choice for cocaine withdrawal.
**Clinical Pearl / High-Yield Fact**
It's essential to note that disulfiram is not a first-line treatment for cocaine withdrawal and should be used under close medical supervision due to its potential side effects. Additionally, the effectiveness of disulfiram in managing cocaine withdrawal symptoms is still a topic of ongoing research and debate.
**Correct Answer:** B. Disulfiram
