Gut Hormones in Obesity, Nicotine and Alcohol Dependence

Summary

The "Gut Hormones in Addiction" study is a proof-of-concept experimental medicine human study to answer the following questions: 1. Does the administration of the hormone desacyl ghrelin reduce core behavioural components of addiction in dependent individuals who have recently stopped smoking tobacco or drinking alcohol, or overweight/obese subjects? 2. Does the administration of the drug Exenatide reduce core behavioural components of addiction in dependent individuals who have recently stopped smoking tobacco or drinking alcohol, or overweight/obese subjects? 3. Does the administration of desacyl ghrelin or Exenatide reduce reward responses to high-calorie foods and appetite in dependent individuals who have recently stopped smoking tobacco or drinking alcohol, or overweight/obese subjects?
