Ny undersøgelse giver håb for vægttabsmedicin mod alkoholisme

En ny undersøgelse fra University of Gothenburg viser, at tirzepatid, det aktive stof i diabetes- og vægttabsmedicin Mounjaro, reducerer alkoholindtag og tilbagefaldslignende adfærd hos rotter og mus. Dette bygger på tidligere forskning om semaglutid i Ozempic og Wegovy, som dæmper alkoholforbrug hos mennesker. Forskere håber på lignende effekter hos patienter med alkoholafhængighed.

En anden undersøgelse tyder på, at vægttabsmedicin kan blive afgørende for mennesker med alkoholafhængighed. Forskere ved University of Gothenburg har vist, at tirzepatid reducerer både alkoholindtag og tilbagefaldslignende adfærd hos rotter og mus. Stoffet dæmper alkoholens virkning på dopamin, et signalstof i hjernens belønningsystem, der gør alkohol belønnende. Elisabet Jerlhag, professor i farmakologi og leder af undersøgelsen, siger: «Dette har en lidt anden tilgang, da det påvirker to signalsystemer, og så tror man, at effekten kan være lidt stærkere, og at man får færre bivirkninger.» Tidligere undersøgelser har bekræftet, at semaglutid, der findes i Ozempic og Wegovy, dæmper alkoholforbrug hos mennesker. Der er endnu ikke gennemført undersøgelser af tirzepatid på mennesker, men dyremodeller betragtes som sammenlignelige i afhængighedssammenhænge. Medicinalfirmaet Eli Lilly rekrutterer til to store kliniske forsøg på patienter med alkoholafhængighed. Jerlhag understreger, at alkoholafhængighed er en heterogen sygdom: «Alkoholafhængighed er en meget heterogen sygdom, folk drikker af mange forskellige grunde. Alle kan reagere lidt forskelligt på disse præparater. Derfor er det ekstremt vigtigt, at der findes mange forskellige mediciner, og med vores forskning bidrager vi til at udvikle viden.» Hun tilføjer, at andre behandlinger som 12-trinsprogrammer og kognitiv adfærdsterapi stadig vil være nødvendige, men farmakologiske muligheder vil hjælpe mange, inklusive dem, der søger hjælp primært for fedme. Alkoholafhængighed er en kronisk hjerne-sygdom, der ændrer belønningsystemet, med høj risiko for tilbagefald og effekter på fysisk og mental sundhed. Nuværende medicin har ofte moderate effekter.

Hvad folk siger

Diskussioner på X fokuserer på en nylig dyrestudie, der viser, at tirzepatid reducerer alkoholindtag og tilbagefaldsadfærd hos rotter og mus, med brugere, der deler positive anekdoter om reduceret trang, selvom nogle eksperter udtrykker skepsis på grund af begrænset humandata.

Weight-loss drugs show early promise for alcohol and other addictions, review finds

Medications such as semaglutide (marketed as Ozempic/Wegovy) could aid treatment of alcohol and other substance use disorders, according to a peer‑reviewed review in the Journal of the Endocrine Society. Early animal and human data suggest these GLP‑1 receptor agonists act on brain reward circuits; lead author Lorenzo Leggio urged caution, saying, “Early research in both animals and humans suggests that these treatments may help reduce alcohol and other substance use.”

Three Cochrane reviews commissioned by the World Health Organization evaluate GLP-1 receptor agonists like tirzepatide, semaglutide, and liraglutide for weight loss in people with obesity. The drugs show substantial weight reduction compared to placebo, but researchers note limitations in long-term data and industry funding influences. Side effects such as nausea are common, raising questions about broader access and safety.

Three new Cochrane reviews conclude that tirzepatide, semaglutide and liraglutide produce clinically meaningful weight loss in adults with obesity, while evidence on long‑term safety, broader outcomes and equitable access remains limited. The findings will inform forthcoming World Health Organization guidance on obesity treatment.

A once-daily 25 mg oral form of semaglutide produced substantial weight loss in adults with obesity in a phase 3 study published in The New England Journal of Medicine, with a 16.6% mean reduction under an adherence-based analysis and 13.6% in the overall analysis. The results were accompanied by improvements in cardiometabolic risk factors and self-reported physical function. Novo Nordisk has submitted the therapy for U.S. approval and says U.S. manufacturing is underway; the FDA is slated to decide in the fourth quarter of 2025.

Preliminary research published in Neurology suggests that GLP-1 medications, including drugs such as Ozempic, may be associated with a modestly lower risk of developing epilepsy in people with type 2 diabetes compared with DPP-4 inhibitors. In the analysis, GLP-1 users were 16 percent less likely to develop epilepsy after statistical adjustment, but researchers stress that the findings show an association, not proof of cause and effect.

Weight loss reversed obesity-related glucose problems in both young and mid-aged mice, but researchers at Ben-Gurion University of the Negev report that, in mid-aged animals, early weight loss coincided with a temporary rise in inflammation-related changes in the hypothalamus, a brain region involved in appetite and energy regulation.

A team led by Leonardo Ferreira at the Medical University of South Carolina is developing a novel therapy combining lab-made insulin-producing cells with engineered immune cells to protect them. Funded by $1 million from Breakthrough T1D, the approach aims to restore beta cell function without immunosuppressive drugs. This strategy builds on prior research and targets all stages of the disease.
