Abstract

Abstract : Background: Using a clinical case example, we describe and discuss the use of oral naltrexone as a novel treatment strategy for nitrous oxide use. Nitrous oxide is an inhalant drug that is readily available and legally obtained. Though frequency of reported cases of substance use disorder for nitrous oxide is low, previous case reports have described severe neurological and psychiatric harms associated with chronic use. Despite this, evidence for pharmacotherapy is currently lacking. Clinical studies have shown variable efficacy for naltrexone across a number of substances including alcohol, nicotine, and stimulants. Case: We present here a case of a 41-year-old man with a substance use disorder for nitrous oxide who was reportedly using of up to four hundred 8 g canisters of nitrous oxide per day. Oral naltrexone was initiated at 50 mg daily in an attempt to decrease cravings. The dose was subsequently titrated to 100 mg daily, resulting in a decrease in nitrous oxide use to less than sixty 8 g canisters per week over a 1-month timeframe. Discussion: Previous literature surrounding naltrexone provides both a plausible mechanism of action for craving reduction as well as a precedent for its use across a number of substances. To our knowledge, use of naltrexone for nitrous oxide use has not been previously described. While clinical studies are currently lacking, this case highlights naltrexone as a possible treatment strategy for nitrous oxide use, with potential to reduce significant harms associated with chronic use.
