Advances in Medications and Tailoring Treatment for Alcohol Use Disorder

Area of Science:

• Neuroscience
• Genetics
• Pharmacology

Background:

• Alcohol use disorder (AUD) is a complex, heritable brain condition with diverse clinical presentations.
• This heterogeneity suggests intricate environmental and biological interactions driving AUD's development and progression.
• Subgrouping AUD based on clinical or pathological traits can simplify understanding its molecular underpinnings.

Purpose of the Study:

• To review the efficacy of AUD medications, comparing outcomes with and without genetic considerations.
• To discuss advancements in preclinical genetic and genomic research applicable to clinical trials.
• To highlight the potential and challenges of a pharmacogenetic approach in treating AUD.

Main Methods:

• Review of existing literature on AUD genetic association studies.
• Comparison of medication efficacy in AUD treatment, with and without genetic data.
• Discussion of preclinical genetic and genomic research findings.

Main Results:

• Genetic polymorphisms are linked to AUD vulnerability, drinking severity, onset age, and craving.
• Some polymorphisms are associated with reduced alcohol consumption.
• Genetically informed patient selection may enhance the effectiveness of AUD treatments.

Conclusions:

• A pharmacogenetic approach offers a promising strategy for personalized AUD treatment.
• Integrating genetic insights into clinical trials could improve medication efficacy.
• Significant scientific, social, and logistical challenges must be addressed for widespread clinical adoption.
