Background and Purpose: Ketamine has emerged as a promising treatment candidate for alcohol use disorder (AUD), yet whether its S- and R-enantiomers differentially regulate ongoing binge-like alcohol self-administration remains unknown. We compared the acute and repeated effects of S- and R-ketamine in a chronic binge-like, front-loaded operant alcohol self-administration paradigm. Experimental...
The drug development process in psychiatry faces significant challenges due to low reproducibility rates in animal testing, which often leads to translation failures. To address this issue, we introduce a new approach in psychiatric drug development: a preclinical randomized controlled trial (preRCT). To demonstrate its potential utility, we conducted a multi-center preRCT using the alcohol...
Abstract The use of psilocybin to treat alcohol use disorder is very promising, but its mechanisms of action remain poorly understood. We combined behavioural, pharmacological and gene expression analyses to decipher the mechanisms of action of psilocybin, for the first time, when injected into the brain. Male Long Evans rats underwent chronic operant ethanol self-administration before testing...
