Animal Models of Drug Relapse and Craving after Voluntary Abstinence: A Review.

Pharmacol Rev 2021 Jul;73(3):1050-1083

Behavioral Neuroscience Branch, Intramural Research Program, National Institute on Drug Abuse, National Institute of Health, Baltimore, Maryland (I.F., M.V., D.J.R., J.J.C., J.M.B., Y.S.), and Center for Social and Affective Neuroscience, Linköping University, Linköping, Sweden

Relapse to drug use during abstinence is a defining feature of addiction. During the last several decades, this clinical scenario has been studied at the preclinical level using classic relapse/reinstatement models in which drug seeking is assessed after experimenter-imposed home-cage forced abstinence or extinction of the drug-reinforced responding in the self-administration chambers. To date, however, results from studies using rat relapse/reinstatement models have yet to result in Food and Drug Administrationapproved medications for relapse prevention. Read More
