About 50% of persons with an alcohol use disorder may have symptoms of alcohol withdrawal syndrome (AWS) when they reduce or discontinue their alcohol consumption. Protracted alcohol withdrawal (PAW), an underestimated and not yet clearly defined clinical condition that follows the acute stage of AWS, is characterized by the presence of substance-specific signs and symptoms (i.e. anxiety, irritability, mood instability, insomnia, craving) common to acute AWS, but persisting beyond the generally expected acute AWS time frames. Considering that PAW symptoms are mainly related to the neuro-adaptive changes of gamma-aminobutyric acid (GABA) and N-methyl-d-aspartate (NMDA) systems, naltrexone, nalmefene, and disulfiram may not be able to suppress the symptoms of PAW. After treatment of the acute phase of AWS, a more specifically pharmacological therapy able to suppress PAW symptoms could perhaps be used earlier and may be more helpful in preventing the risk of alcohol relapse, which remains higher during the first months of treatment. In light of this, medications acting on GABA and NMDA neurotransmitter systems to counterbalance the up-regulation of NMDA and the down-regulation of GABA could be employed in combination and started as soon as possible.

The recognition and management of protracted alcohol withdrawal may improve and modulate the pharmacological treatment of alcohol use disorder

Abstract

About 50% of persons with an alcohol use disorder may have symptoms of alcohol withdrawal syndrome (AWS) when they reduce or discontinue their alcohol consumption. Protracted alcohol withdrawal (PAW), an underestimated and not yet clearly defined clinical condition that follows the acute stage of AWS, is characterized by the presence of substance-specific signs and symptoms (i.e. anxiety, irritability, mood instability, insomnia, craving) common to acute AWS, but persisting beyond the generally expected acute AWS time frames. Considering that PAW symptoms are mainly related to the neuro-adaptive changes of gamma-aminobutyric acid (GABA) and N-methyl-d-aspartate (NMDA) systems, naltrexone, nalmefene, and disulfiram may not be able to suppress the symptoms of PAW. After treatment of the acute phase of AWS, a more specifically pharmacological therapy able to suppress PAW symptoms could perhaps be used earlier and may be more helpful in preventing the risk of alcohol relapse, which remains higher during the first months of treatment. In light of this, medications acting on GABA and NMDA neurotransmitter systems to counterbalance the up-regulation of NMDA and the down-regulation of GABA could be employed in combination and started as soon as possible.
