Which benzodiazepine is preferred for alcohol withdrawal in patients with elevated liver enzymes due to glucuronidation?

• A. Diazepam
• B. Chlordiazepoxide
• C. Lorazepam
• D. Oxazepam

Answer: (C)

In alcohol withdrawal, the safest and most reliable control of symptoms in patients with liver impairment comes from using a benzodiazepine that is eliminated by glucuronidation rather than by hepatic oxidation. Lorazepam is conjugated through glucuronidation with minimal involvement of the cytochrome P450 system, and it has no active metabolites. This means it’s less likely to accumulate and cause prolonged sedation or cognitive impairment when the liver is stressed, providing a safer and more predictable course of withdrawal management in patients with elevated liver enzymes. In contrast, diazepam and chlordiazepoxide depend more on hepatic oxidative metabolism and produce long-acting active metabolites, which can accumulate in liver dysfunction and complicate treatment. Oxazepam also undergoes glucuronidation and is generally safe in liver disease, but lorazepam is commonly favored due to its dosing stability and well-established use in withdrawal protocols.
