Summary
This trial will test whether naltrexone/bupropion can help people who have bariatric surgery to maintain weight loss and control their eating.
Who is the study for?
This trial is for adults aged 18-70 who've had bariatric surgery, are experiencing loss-of-control eating post-surgery, and responded to initial treatment. Participants must be healthy with controlled medical conditions and not using drugs or heavy alcohol. Pregnant women, those with certain heart diseases, uncontrolled diabetes or hypertension, seizure risks, severe psychiatric disorders, or allergies to the study medications cannot join.
What is being tested?
The study tests if Naltrexone/Bupropion (NB) medication helps maintain weight loss and control overeating after bariatric surgery better than a placebo. It's for those who initially responded well to treatments and will compare long-term outcomes between the NB medication group and the placebo group over a period of up to 15 months.
What are the potential side effects?
Possible side effects of Naltrexone/Bupropion may include nausea, headaches, constipation, dizziness, insomnia, dry mouth. There can also be more serious risks like seizures or elevated blood pressure in some individuals.
