What is the first-line treatment for withdrawal?

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

Answer: (D)

The main idea is to reduce the brain’s hyperarousal from withdrawal by boosting GABA inhibition. Benzodiazepines do this most effectively, binding to GABA-A receptors and increasing the time the chloride channel stays open. That dampens excitability, helps control autonomic symptoms, lowers the risk of seizures, and prevents delirium tremens during detox. They’re preferred over other options because they have a wider safety margin and a smoother, longer-acting effect for detoxification. Long-acting benzodiazepines like diazepam or chlordiazepoxide are often used to allow gradual tapering, while in liver impairment, lorazepam or oxazepam are chosen for safer metabolism. Barbiturates can be effective but carry a higher risk of significant respiratory depression and coma, making them less desirable as first-line. Propofol is a potent IV sedative used for deeper sedation or intubated patients, not for routine withdrawal management. Antipsychotics may help with agitation or delirium but do not address the underlying withdrawal neurochemistry and can introduce other risks.
