Alcohol use disorders (AUD) cause significant morbidity and mortality worldwide, but pharmacological treatments for them are underused, despite evidence of efficacy.Acamprosate, naltrexone, nalmefene and disulfiram are all approved in one or more region for the treatment of alcohol use disorders. Baclofen currently has a temporary indication in France. Safety considerations for using psychopharmacological treatments in this patient group include the impact of concurrent alcohol consumption at high levels, multiple physical comorbidities which may interfere with pharmacological effects, distribution and metabolism, and concomitant medication for the treatment of comorbid physical and psychiatric conditions. The five drugs, including an extended-release injectable suspension of naltrexone, have different safety profiles which need to be balanced with the objective of treatment (initiation or continuation of abstinence, or reduction of drinking), individual patient preferences and comorbid conditions. Appropriate treatment will be based on the unique riskbenefit profile in each case.
KEY POINTS Acamprosate has an excellent safety profile and is recommended as first line treatment for patients wishing abstinence. Naltrexone and nalmefene are contraindicated with opioid-containing medication, but have reasonable tolerability The disulfiram-alcohol reaction is integral to its use, but careful patient selection and monitoring can mitigate safety risks Baclofen is a CNS depressant so there are potential concerns regarding overdose: it may have a role in patients with severe liver disease Pharmacological treatments for alcohol dependence 3
