Treatment for Alcohol Abuse
The most effective treatment for alcohol abuse is a combination of pharmacotherapy (particularly naltrexone or baclofen) with cognitive behavioral therapy (CBT) or another evidence-based psychotherapy, rather than usual care or non-specific counseling services. 1
Pharmacotherapy Options
First-line Medications
Naltrexone:
- Dosage: 50 mg once daily for 12 weeks 2
- Mechanism: Blocks opioid receptors, reducing alcohol craving and pleasure from drinking
- Evidence: Reduces relapse rates (31% vs 60%), increases abstention rates (51% vs 23%), and decreases drinking days compared to placebo 2
- Best for: Patients who want to reduce heavy drinking days
- Contraindications: Opioid use, severe liver disease
Baclofen:
- Dosage: Start at 5 mg TID, titrate up to 10 mg TID 3
- Mechanism: GABA-B receptor agonist
- Best for: Patients with liver disease (preferred medication for this population)
Acamprosate:
- Dosage: 666 mg TID for patients ≥60 kg 3
- Mechanism: Modulates glutamate neurotransmission
- Best for: Patients who have already achieved abstinence and want to maintain it
- Advantage: Safe in liver disease
Second-line Medications
- Disulfiram:
Psychosocial Interventions
Cognitive Behavioral Therapy (CBT)
- Meta-analysis shows CBT combined with pharmacotherapy is superior to usual care plus pharmacotherapy (g range, 0.18-0.28) 1
- Particularly effective for patients who drink to cope with negative emotions 3
- Focuses on identifying triggers and developing coping skills
Motivational Interviewing
- Effective for patients ambivalent about alcohol cessation 3
- Helps patients recognize problems and develop commitment to change
Support Groups
- Alcoholics Anonymous and other peer support groups recommended as adjuncts to formal treatment 3
Treatment Algorithm
Step 1: Assessment and Stabilization
- Assess withdrawal risk using CIWA-Ar score:
- ≤7: Mild - Monitor, may not require medication
- 8-14: Moderate - Initiate benzodiazepine treatment
- ≥15: Severe - Aggressive benzodiazepine treatment, consider inpatient management 3
- Provide thiamine supplementation: 100-300 mg IV three times daily for high-risk patients, followed by oral maintenance of 50-100 mg daily 3
- For patients with liver disease: Use short-acting benzodiazepines (oxazepam or lorazepam) 3
Step 2: Initiate Combined Treatment
- Start pharmacotherapy based on patient profile:
- No liver disease: Naltrexone 50 mg daily
- With liver disease: Baclofen starting at 5 mg TID
- Already abstinent: Acamprosate 666 mg TID
- Begin CBT or another evidence-based therapy concurrently
- CBT is equally effective as other evidence-based therapies when combined with pharmacotherapy 1
- Schedule regular sessions (typically weekly)
Step 3: Maintenance and Monitoring
- Continue medications for 3-12 months with ongoing psychosocial support 3
- Monitor using biomarkers such as Phosphatidylethanol (PEth), Ethyl Glucuronide (EtG), and Ethyl Sulfate (EtS) 3
- Schedule follow-up liver function tests in 2-4 weeks for patients with alcoholic liver disease 3
Nutritional Support
- Ensure adequate protein intake (1.2-1.5 g/kg/day) and caloric intake (35-40 kcal/day) 3
- Supplement with B vitamins, particularly thiamine, folate, and multivitamins 3
Common Pitfalls to Avoid
- Prescribing medications without psychosocial support - Combined treatment is superior to either alone 1
- Discontinuing treatment prematurely - Optimal duration is at least 3-12 months 3
- Failing to address comorbid psychiatric conditions - These can trigger relapse if untreated
- Not monitoring for medication side effects - Regular follow-up is essential
- Overreliance on disulfiram - Limited evidence supports its effectiveness outside supervised settings 4
Special Considerations
- For patients with liver disease, baclofen is the preferred medication 3
- Naltrexone and disulfiram are contraindicated in decompensated hepatic disease 3
- The COMBINE study showed that naltrexone with medical management could be effectively delivered in primary care settings, serving patients who might otherwise not receive treatment 5
The evidence clearly demonstrates that combining pharmacotherapy with evidence-based psychotherapy is more effective than either approach alone, with naltrexone and CBT showing particularly strong evidence of efficacy 1, 5.
