Non-physiological mechanisms influencing disulfiram treatment of alcohol use disorder: A grounded theory study

Supervised Disulfiram Should Be Considered First-Line Treatment for Alcohol Use Disorder

ABSTRACT

Despite the prevalence of alcohol use disorder (AUD) in the United States, the armamentarium of FDA-approved medications available for AUD treatment is remarkably small. Disulfiram, 1 of only 3 approved medications, is consistently designated as a second-line option in national treatment guidelines, citing inconsistent evidence, lack of patient preference, and safety concerns. These concerns, however, stem from a misguided interpretation of the evidence that exclusively relies upon double-blind randomized controlled trials (RCT). When viewed instead as both a medication and a behavioral intervention, open-label RCTs become a more appropriate research method, yielding overwhelmingly favorable efficacy data for disulfiram, and supervised disulfiram, in particular. With these data in mind, supervised disulfiram should be redesignated as a first-line intervention in both treatment guideline creation and clinical pathway tools. The addiction medicine community can no longer afford to neglect this critical therapeutic resource.

Impact of an Alcohol-based hand sanitizer usage during COVID-19 pandemic on disulfiram treatment: A South Indian psychiatrist's practice experiences

Background: Alcohol-based hand sanitizer (ABHS) usage has become one of the COVID-19 pandemic-related adapted responses. Some disulfiram-ethanol reactions are reported in people who use alcohol-based hand rub/sanitizer and take Disulfiram as a treatment for their alcohol use disorders. Aim & Objective: To determine the practice experiences of psychiatrists on disulfiram prescription to alcohol use disorder victims. Methodology: A cross-sectional study on the psychiatrists to find the experiences of disulfiram prescription to their clients with alcohol use disorders during the COVID-19 pandemic. Results: Nearly 84 (51%) were reverted with a completed questionnaire. Among the respondents, 28 (33.3%) of the respondents decreased to prescribe Disulfiram, 48 (57.1%) reported that their patients stopped using ABHS due to fear of Disulfiram-Ethanol Reaction (DER), and 20 (23.8%) responders notified that their patients were expressed their worry on DER with Disulfiram and ABHS. Conclusion: Disulfiram prescribed for alcohol use disorders; treatment got peculiar experiences with the incidences of DER reported with Alcohol-based hand sanitizer. Many practitioners were scared to prescribe disulfiram due to DER with ABHS. The prevailing evidence that there is no possibility of cutaneous application of ABHS producing enough significant DER. Hence using ABHS is not a contraindication for disulfiram prescription.

Is Alcohol in Hand Sanitizers Absorbed Through the Skin or Lungs? Implications for Disulfiram Treatment

Aim

In view of the increase in the use of ethanol-containing hand sanitizers throughout the world due to the current COVID-19 pandemic, we wished to review the possible risks to patients treated with disulfiram, following a case report in which an apparent DER (disulfiram–ethanol reaction) was attributed to the cutaneous absorption of alcohol from hand sanitizers as well as by inhalation of vapour.

Method

Simple experiments to assess the levels of absorption by each route separately.

Results

Our results strongly suggest that while amounts of alcohol sufficient to cause a DER may be inhaled when hand sanitizers are used in confined spaces, absorption can be avoided by dispersal of the fumes, and absorption from the skin alone does not occur in pharmacologically significant quantities.

Conclusion

Warnings about absorption of alcohol through the skin from hand sanitizers and products such as perfumes, deodorants and after-shave (whose use is often warned against when disulfiram is prescribed) should be modified accordingly.
