The combination treatment of Naltrexone and Bupropion SR has shown considerable effectiveness in supporting weight loss, with clinical studies indicating its potential for individuals to achieve a significant reduction of up to 10% of their body weight within a year. These studies have highlighted the impactful nature of this combination therapy in aiding weight management, particularly when complemented by lifestyle adjustments such as dietary modifications and increased physical activity.
Naltrexone + Bupropion SR, when used together for weight management, harnesses the properties of two medications to influence different aspects related to weight loss.
Naltrexone primarily works by affecting the reward system in the brain, reducing the desire for certain foods and potentially diminishing the feelings of pleasure associated with eating.
Bupropion SR, on the other hand, acts as an antidepressant and smoking cessation aid, but in this combination, its effect on weight loss is thought to be related to appetite suppression and potentially boosting metabolism.
Together, these medications appear to complement each other: Naltrexone helps curb cravings, while Bupropion SR may aid in reducing appetite and potentially increasing calorie expenditure. This combined approach aims to support individuals in managing their weight by influencing both food intake and the body's metabolic responses.
Naltrexone + Bupropion SR are two medications that make up the weight loss medication Contrave. This combination is used for weight management in adults with obesity or overweight people with weight-related health conditions.
Naltrexone is mainly used to manage alcohol and opioid dependence and, in this combination, may help reduce food cravings.
Bupropion SR is an antidepressant typically taken to help you stop smoking, but it may also help control appetite and potentially boost metabolism.
Together, these medications aim to help you manage your weight by influencing food intake and metabolic responses.
Individual weight loss results with Naltrexone + Bupropion SR can vary widely. In clinical trials, people taking this combination medication for weight management experienced varying degrees of weight loss. On average, their weight loss ranged from approximately 5% to 10% of their initial body weight over the course of the trials, which typically lasted around 1–2 years.
Your weight loss can be influenced by various factors, including individual responses to the medication, consistency with treatment, lifestyle changes, metabolic differences and overall health. Some people might experience more significant weight loss, while others may see more moderate changes.
