This paper develops sustained-release nor-LAAM-loaded PLGA microparticles for OUD treatment, showing prolonged drug release and reduced fentanyl choice and withdrawal in rats.

This study shows that opioid withdrawal leads to sex-specific changes in fentanyl choice and mesolimbic gene expression in rats, with males showing increased fentanyl preference and females showing transcriptional hyperfunction.

This study shows that pain-related manipulations in rats do not increase opioid self-administration, reinstatement of seeking, or choice over food.

This study evaluates lorcaserin's effect on heroin-vs-food choice in rhesus monkeys, finding it ineffective compared to saline and naltrexone.
