Naltrexone 8mg & Bupropion 90mg (Generic)

Description

Naltrexone and bupropion are combined in a single medication called Contrave, primarily used for weight management in individuals who are overweight or obese. Naltrexone is an opioid receptor antagonist that helps reduce food cravings, while bupropion is an antidepressant that can also suppress appetite and increase energy expenditure. The combination of these medications is thought to work synergistically to help promote weight loss. Contrave is typically used alongside a reduced-calorie diet and increased physical activity to achieve and maintain weight loss goals. It should be used under medical supervision due to potential side effects and interactions with other medications.

Naltrexone & Bupropion is a combination medication primarily used for weight management in adults who are overweight or obese, especially when combined with diet and exercise. The brand name for this combination is Contrave .

What Is It?

• Naltrexone: An opioid receptor antagonist. It blocks the brain’s opioid receptors and may reduce cravings and emotional eating.
• Bupropion: An antidepressant (also used for smoking cessation) that affects dopamine and norepinephrine. It helps reduce appetite and improve energy/mood.

Together, they act on two key areas in the brain:

1. Hypothalamus – controls hunger
2. Mesolimbic reward system – related to cravings and emotional eating
