Objective:
To investigate whether dexmedetomidine (DEX), as adjunctive therapy to benzodiazepine (BZD), is superior to BZD alone in critically ill patients with alcohol withdrawal syndrome (AWS).
Data Sources:
PubMed Central, Cochrane CENTRAL, ClinicalTrials.gov and Google Scholar were used as search databases. Specific keywords and MeSH terms were "dexmedetomidine," "benzodiazepine," and "alcohol withdrawal syndrome." The last search was on September 16, 2022.
Study Selection And Data Extraction:
Randomized controlled trials (RCTs) and nonrandomized/cohort studies exploring the use of DEX in the management of AWS were included. A total of 12 studies were included in the systematic review and 7 in the meta-analysis.
Data Synthesis:
The intensive care unit length of stay (ICU LOS) was found to have a mean difference (MD) of 48.06 [37.48, 58.64], P = <0.001 for the cohort subgroup, significantly favoring the DEX arm, but, in contrast, pooled RCT data showed a result of -20.07 [-36.86, -3.28], P = 0.02, a shorter ICU LOS for the DEX arm. Bradycardia and hypotension incidence significantly favored the BZD arm in both subgroups. This study compares the effectiveness of adjunctive DEX in clinical practice and aims to help providers in critical decision-making by compiling and analyzing the best current available evidence of its use in AWS.
Conclusions:
Based on low to very low level of evidence, adjunctive DEX showed no significant difference for ICU LOS when compared with BZD alone. Pooled randomized trials potentially show a benefit but are similarly limited by their low quality of evidence.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
