**Question:** A 46-year-old man presented to the casualty with acute onset of seeing lizards all around him in the room. He has been violent towards members of his brother who tried to bring him to hospital. On history he has a longstanding history of drinking alcohol and using cannabis for 7 years. He had missed his drinks for the last 3 days. On examination his blood pressure is high and he has global confusion. Which of the following can be used in the immediate treatment of the condition?

A. Haloperidol
B. Flumazenil
C. Naloxone
D. Benzodiazepine (e.g., Midazolam)

**Correct Answer:** **D. Benzodiazepine (e.g., Midazolam)**

**Core Concept:** The presented case demonstrates a scenario of acute alcohol withdrawal (AW) and delirium tremens (DTs) in a chronic heavy alcohol user. AW and DTs are severe complications of abrupt cessation of alcohol consumption in individuals with longstanding alcohol dependence.

**Why the Correct Answer is Right:** The correct answer is benzodiazepine (e.g., Midazolam) because this medication can rapidly control the agitation and neuropsychiatric symptoms associated with alcohol withdrawal, including DTs. Benzodiazepines act as GABA agonists, increasing the inhibitory neurotransmission in the central nervous system (CNS) and providing symptomatic relief. Midazolam is a commonly used choice for the management of DTs due to its rapid onset, short half-life, and easy titration.

**Why Each Wrong Option is Incorrect:**

**A. Haloperidol:** Haloperidol is an antipsychotic medication primarily used to treat schizophrenia and other psychotic disorders. Although it may have some antipsychotic effect in DTs, it is not a primary treatment option for alcohol withdrawal symptoms.

**B. Flumazenil:** Flumazenil is an antagonist of benzodiazepine receptors and is primarily used to reverse the effects of benzodiazepines (e.g., midazolam) overdose. In this case, it would not be effective in treating alcohol withdrawal symptoms.

**C. Naloxone:** Naloxone is an opioid antagonist used for opioid overdose reversal. It has no role in treating alcohol withdrawal symptoms.

**Clinical Pearls:**

1. In cases of alcohol withdrawal, it is essential to initiate the management with benzodiazepine (e.g., midazolam) and titrate the dose gradually to control agitation and neuropsychiatric symptoms.
2. Monitoring for complications like seizures, arrhythmias, and hypotension is crucial during benzodiazepine administration.
3. Consider referring the patient to a specialized ward or intensive care unit for further management and monitoring of alcohol withdrawal syndrome.
