Naltrexone primarily functions as an opioid antagonist. In the context of weight loss, it helps modulate the reward pathways that drive overeating and emotional eating behaviors.
2.2. Synergy with Other Medications
When combined with bupropion, another medication that influences neurotransmitters related to appetite and mood, naltrexone can enhance weight loss outcomes.
3. Clinical Evidence Supporting Naltrexone for Weight Loss
Naltrexone and weight loss have been the subject of various clinical trials aimed at evaluating its efficacy and safety as a weight management tool.
3.1. Key Studies
