[Pharmacological post-acute treatment of alcohol use disorder: Established strategies and innovative approaches].

Alcohol use disorders are common and contribute significantly to the global burden of disease. The treatment of alcohol dependence includes the acute withdrawal phase and the post-acute rehabilitation phase. The primary goal of post-acute treatment is long-term abstinence, although reduction of alcohol consumption is also recognized as an intermediate goal. In addition to psychosocial and psychotherapeutic interventions, the use of medications is recommended. In Switzerland, four medications (acamprosate, naltrexone, nalmefene, and disulfiram) are approved for post-acute treatment. Their efficacy in reducing relapse risk, drinking days, and overall alcohol consumption is well established. Baclofen, topiramate, and gabapentin are used "off-label", but sufficient evidence of their effectiveness is still lacking. Innovative approaches such as cannabidiol, psilocybin, and glucagon-like peptide-1 receptor agonists show promising therapeutic potential, which needs to be confirmed in further clinical studies. The use of pharmacological interventions can help improve patient outcomes, reduce the need for inpatient treatment, and lower healthcare costs.
