Good Weight Loss With Bupropion Plus Naltrexone

man on scaleA 2013 article by Smith et al. in the journal Diabetes, Obesity, and Metabolism reports that obese patients treated with the combination of bupropion (Wellbutrin) and naltrexone (Revia) had excellent weight loss and reduction in body fat compared to those treated with either drug alone or with placebo. The combination resulted in about a 14% reduction in body fat, while placebo, bupropion alone, and naltrexone alone each brought about only a 3-4% reduction.

Editor’s Note: Researcher Roger McIntyre is an expert on the metabolic syndrome in patients with bipolar illness and has been using this combination with success in patients with mood disorders.  He finds the combination of bupropion and naltrexone more helpful than the anticonvulsants topiramate (Topomax) or zonisamide (Zonegran) or the anti-diabetes drug metformin.

Since obesity and the metabolic syndrome occur in approximately 40 to 50% of bipolar patients and significantly increases cardiovascular risks such as heart attack and stroke, and since bupropion is widely used in the treatment of bipolar depression, this combination appears worthy of consideration for those with obesity. Its use should be accompanied by a good diet and an exercise regimen. Decreasing cardiovascular risk is a very important component of the treatment of bipolar disorder, and the combination of bupropion and naltrexone could have substantial benefits.
