Two Phase II clinical trials demonstrated that a combination of bupropion SR and naltrexone is associated with greater weight loss than bupropion SR alone, naltrexone alone, or placebo in subjects with uncomplicated obesity. The current study investigated the safety and efficacy of 2 doses of the combination of naltrexone SR and bupropion SR compared to placebo in obese subjects with uncomplicated obesity and in those with overweight/obesity and hypertension and/or dyslipidemia.
The purpose of this study is to determine whether 2 doses of the combination of naltrexone SR and bupropion SR are safe and effective in the treatment of obesity.
