Abstract
Rationale: Glucagon-like peptide-1 (GLP-1) receptor agonists reduce alcohol consumption in rodents and non-human primates. Semaglutide is a new long-acting GLP-1 receptor agonist, widely used in the clinic against type 2 diabetes and obesity. It is also reported to reduce alcohol intake in rodents.
Objectives: This study investigates the possible inhibitory effect of semaglutide on alcohol intake in alcohol-preferring African green monkeys.
Methods: We performed a vehicle-controlled study on male monkeys that had demonstrated a preference for alcohol. In the monkeys selected for voluntary alcohol drinking, alcohol consumption was measured for ten days at baseline (Monday to Friday for two weeks). During this period, the monkeys had access to alcohol 4 h per day and free access to water 24 h per day. After two weeks of baseline measurements, the monkeys were randomized to semaglutide or vehicle. Each group consisted of ten monkeys, and the two groups were balanced with respect to baseline alcohol intake. Following the baseline period, the monkeys were treated with escalating doses of semaglutide (up to 0.05 mg/kg) or vehicle subcutaneously twice weekly for two weeks during which period alcohol was not available. After uptitration, the monkeys had access to alcohol 4 h daily for 20 days (Monday to Friday for 4 weeks), and alcohol consumption was measured. During this alcohol exposure period, treatment with semaglutide (0.05 mg/kg twice weekly) or vehicle continued for three weeks followed by a one-week washout period.
Results: Compared to the vehicle, semaglutide significantly reduced alcohol intake. There were no signs of emetic events or changes in water intake.
Conclusions: These data demonstrate for the first time the potent effect of semaglutide in reducing voluntary alcohol intake in non-human primates and further substantiate the need for clinical trials investigating the effect of semaglutide in patients with alcohol-use disorder.

Official Journal of the European Behavioural Pharmacology Society (EBPS)
Psychopharmacology is an international journal that covers the broad topic of elucidating mechanisms by which drugs affect behavior. The scope of the journal encompasses the following fields:
Human Psychopharmacology: Experimental
This section includes manuscripts describing the effects of drugs on mood, behavior, cognition and physiology in humans. The journal encourages submissions that involve brain imaging, genetics, neuroendocrinology, and developmental topics. Usually manuscripts in this section describe studies conducted under controlled conditions, but occasionally descriptive or observational studies are also considered.
Human Psychopharmacology: Clinical and Translational
This section comprises studies addressing the broad intersection of drugs and psychiatric illness. This includes not only clinical trials and studies of drug usage and metabolism, drug surveillance, and pharmacoepidemiology, but also work utilizing the entire range of clinically relevant methodologies, including neuroimaging, pharmacogenetics, cognitive science, biomarkers, and others. Work directed toward the translation of preclinical to clinical knowledge is especially encouraged. The key feature of submissions to this section is that they involve a focus on clinical aspects.
Preclinical psychopharmacology: Behavioral and Neural
This section considers reports on the effects of compounds with defined chemical structures on any aspect of behavior, in particular when correlated with neurochemical effects, in species other than humans. Manuscripts containing neuroscientific techniques in combination with behavior are welcome. We encourage reports of studies that provide insight into the mechanisms of drug action, at the behavioral and molecular levels.
Preclinical Psychopharmacology: Translational
This section considers manuscripts that enhance the confidence in a central mechanism that could be of therapeutic value for psychiatric or neurological patients, using disease-relevant preclinical models and tests, or that report on preclinical manipulations and challenges that have the potential to be translated to the clinic. Studies aiming at the refinement of preclinical models based upon clinical findings (back-translation) will also be considered. The journal particularly encourages submissions that integrate measures of target tissue exposure, activity on the molecular target and/or modulation of the targeted biochemical pathways.
Preclinical Psychopharmacology: Molecular, Genetic and Epigenetic
This section focuses on the molecular and cellular actions of neuropharmacological agents / drugs, and the identification / validation of drug targets affecting the CNS in health and disease. We particularly encourage studies that provide insight into the mechanisms of drug action at the molecular level. Manuscripts containing evidence for genetic or epigenetic effects on neurochemistry or behavior are welcome.
