Some individuals taking fashionable new diabetes and weight-loss medicine together with Ozempic, Wegovy, Zepbound and Mounjaro have reported decreased cravings for substances apart from meals. The drugs appear to dampen the consequences of medicine starting from nicotine to alcohol—however scientists haven’t been capable of totally determine why.
A current preliminary research in Scientific Reviews gives clues to how the brand new class of medicine could make individuals drink much less alcohol—and really feel much less drunk after they do. The research authors recommend that understanding the medicine’ mechanism in your entire physique—not simply the mind—might open up avenues for treating alcohol use dysfunction.
“There’s numerous motion within the mind, however what we had been attempting to argue in our paper is that there additionally might be motion within the intestine,” says research co-author Alex DiFeliceantonio, an appetitive neuroscientist at Virginia Tech. “We have to have a look at each to essentially totally perceive how these medicine are working to scale back the consumption of drugs with abuse legal responsibility.”

The medicine promote the discharge of insulin and make individuals really feel full by mimicking the pure intestine hormone glucagon-like peptide 1 (GLP-1). Scientists largely agree that the first method GLP-1 medicine trigger weight reduction is thru their results on emotions of satiety within the mind—inflicting individuals to really feel full quicker and finally eat smaller meals. Previous proof suggests the mind’s pleasure and satiety pathways overlap, which has spurred researchers to suggest that the GLP-1 medicine could also be additionally quieting reward indicators key in sure addictive behaviors, reminiscent of ingesting alcohol.
However the medicine additionally trigger a physiological response within the intestine: they decelerate the motion of meals and liquids from the abdomen into the small gut, a course of referred to as gastric emptying.
Individuals taking these medicine “can’t eat fairly as a lot, as a result of the meals is staying of their abdomen longer,” DiFeliceantonio says. “The fascinating factor about alcohol is it’s not properly absorbed within the abdomen. It must empty into the gut to be absorbed and so that you can really feel the consequences.”
If the GLP-1 medicine delay gastric emptying, alcohol could take longer to achieve the mind. “We all know that slowing down a drug makes it much less rewarding,” DiFeliceantonio says—and decreasing reward could assist deal with habit. “The substance issues, sure, however the pace at which it will get to your mind additionally issues,” she says.
DiFeliceantonio and her colleagues got down to take a look at this speculation. In a makeshift bar of their lab, they gave vodka combined in orange or cranberry juice to 10 individuals who had been taking one of many GLP-1 drugs for weight reduction and an identical variety of individuals in a management group. Not one of the members had alcohol use dysfunction. Within the span of an hour, all members drank three vodka doses, calculated primarily based on their physique measurement, to extend their breath alcohol content material (BrAC) to 0.08 %. That is equal to a blood alcohol content material (BAC) of 0.1 %, previous the authorized restrict for driving within the U.S.
The researchers surveyed the members about how drunk they felt and took a number of breath alcohol measurements over 4 hours, or till the members’ BrAC ranges dropped beneath 0.02 %.
“What we discovered was that, particularly within the first 20 to half-hour after ingesting the alcohol, there was a decrease breath alcohol content material within the group taking a GLP-1 receptor agonist, they usually reported that they felt much less drunk,” DiFeliceantonio says. All of the members reached related BrAC ranges after about an hour, however slowing the alcohol’s impact on the mind made individuals really feel much less intoxicated, she says.
Neither adjustments in blood glucose nor nausea (a standard aspect impact of GLP-1 drugs) defined how intoxicated individuals felt, the researchers discovered.
The research has a number of limitations. The pattern measurement was small, and completely different members had been taking completely different weight-loss drugs, which act on completely different intestine hormone receptors or are prescribed at various dosages. Ideally in drug research researchers would preserve the treatment and dose constant, however this research is an effective begin, says Carolina Haass-Koffler, an habit researcher and affiliate professor of psychiatry at Brown College, who was not concerned within the research.
“Alcohol use dysfunction is a fancy, systemic illness and includes not solely mind dysfunction but in addition a metabolic element,” Haass-Koffler says. “I actually like the mixing of the whole-body idea on this research.”
She notes, nonetheless, that introducing GLP-1 drugs to a brand new inhabitants requires cautious analysis of the dangers and advantages. “Security knowledge are on the market for individuals with diabetes and now individuals taking the treatment for weight problems,” however the scientific presentation might be utterly completely different in individuals with alcohol use dysfunction, Haass-Koffler says. DiFeliceantonio wouldn’t advocate GLP-1 medicine as future frontline remedies for somebody with alcohol use dysfunction who’s underweight.
Randomized managed trials of those medicine have proven some promise in treating alcoholism. A 2022 scientific trial discovered that the early-generation GLP-1 treatment exenatide lowered alcohol cravings in individuals with alcohol use dysfunction, and one other trial printed in February discovered that individuals with weight problems and alcohol use dysfunction drank much less when handled with semaglutide, the generic identify for Wegovy and Ozempic.
“It looks as if a extremely small factor, to simply decelerate [alcohol reaching the brain] slightly,” DiFeliceantonio says. “From this research, we are able to’t definitively say that is the rationale that individuals taking GLP-1 drugs drink much less, but it surely’s including to this physique of proof of what the mechanism is.”
It’s Time to Stand Up for Science
If you happen to loved this text, I’d wish to ask on your help. Scientific American has served as an advocate for science and business for 180 years, and proper now would be the most important second in that two-century historical past.
I’ve been a Scientific American subscriber since I used to be 12 years outdated, and it helped form the way in which I have a look at the world. SciAm at all times educates and delights me, and conjures up a way of awe for our huge, lovely universe. I hope it does that for you, too.
If you happen to subscribe to Scientific American, you assist be certain that our protection is centered on significant analysis and discovery; that now we have the sources to report on the selections that threaten labs throughout the U.S.; and that we help each budding and dealing scientists at a time when the worth of science itself too usually goes unrecognized.
In return, you get important information, charming podcasts, good infographics, can’t-miss newsletters, must-watch movies, difficult video games, and the science world’s finest writing and reporting. You may even reward somebody a subscription.
There has by no means been a extra essential time for us to face up and present why science issues. I hope you’ll help us in that mission.
