Which medication class is first-line for treating acute alcohol withdrawal tremors and seizures?

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

Answer: (A)

The key idea is that acute alcohol withdrawal causes a surge of brain excitability, which can produce tremors and, more importantly, seizures. Benzodiazepines top this situation because they enhance GABA’s inhibitory effect at the GABA-A receptor. By increasing chloride flow into neurons, they calm neural activity, reducing tremors, autonomic symptoms, and the risk of seizures or progression to delirium tremens. Because they address the core withdrawal physiology, they’re considered the first-line treatment.

In practice, longer-acting benzodiazepines are commonly used to provide steady GABAergic support—think of diazepam or chlordiazepoxide for typical inpatient management. Lorazepam is often chosen for patients with liver disease since it’s less dependent on hepatic metabolism. When a seizure occurs acutely, an IV benzodiazepine such as diazepam or lorazepam is given promptly to stop the seizure activity. As the withdrawal symptoms improve, the dose is tapered gradually, guided by the patient’sSigns and symptoms and scoring systems like CIWA-Ar.

其他 drug classes don’t fit as well for this scenario because they don’t reliably address the underlying mechanism. Barbiturates can also depress respiration but carry higher overdose risk and more complicated monitoring. Antipsychotics might help agitation but don’t prevent withdrawal seizures and can worsen delirium or other complications. Opioids don’t treat alcohol withdrawal and can complicate management.
