Contrave is a weight-loss medication composed of two active ingredients: naltrexone hydrochloride and bupropion hydrochloride [1].
What is the combination of naltrexone and bupropion for weight loss?
Naltrexone, an opioid antagonist, and bupropion, an antidepressant, are combined in Contrave to aid in weight management [1]. Naltrexone works by affecting the areas of the brain that control hunger and cravings, while bupropion impacts the hypothalamus, an area of the brain regulating appetite [2]. This combination is thought to target specific pathways in the brain involved in regulating food intake and energy balance [1].
How does Contrave work to help people lose weight?
The dual action of naltrexone and bupropion in Contrave is designed to reduce appetite and increase feelings of fullness [1]. Naltrexone, when used in addiction treatment, blocks the effects of opioids, which can also be involved in reward pathways related to food. Bupropion affects neurotransmitters like dopamine and norepinephrine, which can influence mood and appetite control [2]. Together, they are believed to modify eating behaviors and support weight loss in conjunction with a reduced-calorie diet and increased physical activity [1].
