What medications are recommended for a 63-year-old male patient with alcohol use disorder (alcoholism) to manage withdrawal symptoms?

From the Guidelines

For alcohol withdrawal management in a 63-year-old male alcoholic patient, benzodiazepines are the first-line medication, with long-acting options like diazepam or chlordiazepoxide preferred for most patients, and shorter-acting options like lorazepam or oxazepam recommended for those with liver impairment, as stated in the most recent guidelines 1. When managing alcohol withdrawal, it's essential to assess the severity of symptoms using a validated scale like the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) to determine the appropriate dosage of benzodiazepines.

• The CIWA-Ar score can help guide the treatment, with a score >8 indicating moderate withdrawal and a score ≥15 indicating severe withdrawal.
• Benzodiazepines work by enhancing GABA activity, which counteracts the CNS hyperexcitability caused by alcohol withdrawal.
• For patients with liver impairment, shorter-acting benzodiazepines like lorazepam (1-4mg every 4-6 hours) or oxazepam (15-30mg every 4-6 hours) are safer, as they have a lower risk of accumulation and toxicity.
• After acute withdrawal, medications for maintaining sobriety, such as naltrexone, acamprosate, or disulfiram, may be considered, as well as gabapentin for post-acute withdrawal symptoms.
• It's crucial to start with lower doses and monitor the patient closely for adverse effects, especially in older patients.
• Thiamine supplementation is also recommended to prevent Wernicke encephalopathy, with a dosage of 100-300 mg/day for 4-12 weeks 1.
• The treatment goals are to provide symptomatic relief, prevent complications, and maintain abstinence as a long-term treatment, with psychiatric consultation recommended for evaluation and acute management of alcohol withdrawal syndrome and long-term abstinence planning 1.

From the FDA Drug Label

INDICATIONS Diazepam is indicated for the management of anxiety disorders or for the short- term relief of the symptoms of anxiety. Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic In acute alcohol withdrawal, diazepam may be useful in the symptomatic relief of acute agitation, tremor, impending or acute delirium tremens and hallucinosis INDICATIONS AND USAGE: Chlordiazepoxide HCI Capsules are indicated for the management of anxiety disorders or for the short-term relief of symptoms of anxiety, withdrawal symptoms of acute alcoholism, and preoperative apprehension and anxiety.

Medications suggested for alcohol withdrawal:

• Diazepam (PO) 2 may be useful in the symptomatic relief of acute agitation, tremor, impending or acute delirium tremens and hallucinosis in acute alcohol withdrawal.
• Chlordiazepoxide (PO) 3 is indicated for the short-term relief of withdrawal symptoms of acute alcoholism. Key considerations:
• The effectiveness of these medications in long-term use (more than 4 months) has not been assessed by systematic clinical studies.
• The physician should periodically reassess the usefulness of the drug for the individual patient.

From the Research

Medications for Alcohol Withdrawal

The following medications are suggested by medical guidelines for alcohol withdrawal:

• Benzodiazepines, which include:
  • Lorazepam
  • Chlordiazepoxide
  • Oxazepam
  • Diazepam 4, 5, 6, 7, 8
• The choice of benzodiazepine may depend on various factors, such as the patient's age, liver function, and the severity of withdrawal symptoms 4, 5, 7
• For elderly patients, short-acting benzodiazepines like oxazepam and lorazepam may be preferred to minimize the risk of excessive sedation 7
• Diazepam may be the preferred benzodiazepine for treating moderate to severe alcohol withdrawal due to its rapid onset of action and long elimination half-life 4

Dosage and Administration

• The dosage and frequency of benzodiazepines should be individualized and based on validated alcohol withdrawal severity measures 7
• A symptom-triggered regimen is often preferred over a fixed tapering dose regimen 6
• The use of adjunctive agents like beta-blockers, clonidine, carbamazepine, and haloperidol may be considered for symptoms not controlled by benzodiazepines 7

Special Considerations

• Elderly patients with alcohol withdrawal symptoms should be considered for admission to an inpatient setting for supportive care and management 7
• The age of the patient should not deter clinicians from helping the patient achieve successful alcohol treatment and rehabilitation 7
