What medication is used to prevent alcohol withdrawal seizures?

• A. Barbiturates
• B. Antipsychotics
• C. Benzodiazepines
• D. Antidepressants

Answer: (C)

Alcohol withdrawal seizures are driven by a sudden loss of alcohol’s depressive effect on brain activity, leading to increased neuronal excitability. The medication used to prevent these seizures is a benzodiazepine. They work by enhancing the inhibitory action of GABA at the GABA-A receptor, increasing chloride influx into neurons and dampening CNS hyperexcitability. This directly counteracts the surge in activity that drives withdrawal seizures, reducing the risk as withdrawal progresses. In clinical practice, benzodiazepines are started during withdrawal and can be given on a symptom-triggered or scheduled basis to control agitation, autonomic signs, and prevent progression to more severe withdrawal. They are preferred over other classes because they have a safer profile and effectively stamp out the hyperexcitability that leads to seizures. Barbiturates can be used in more refractory cases but carry higher risks, while antipsychotics and antidepressants do not prevent withdrawal seizures and are not the primary choice for this purpose.
