Neurobehavioral Substrates of Propranolol's Effects on Drug Cue Reactivity

NCT03309943 ↗

RandomizedParallel-groupTriple-blindBasic science

Summary

The central objective of this project is to obtain proof-of-concept data demonstrating the effects of propranolol (a beta-adrenergic antagonist) on neurobiological responses to personal smoking environments and behavioral responses in a laboratory smoking behavior task. Human cigarette smokers (N = 50) will take photographs of locations where they do and do not smoke cigarettes. They will then be randomly assigned to receive either propranolol (40 mg) or placebo prior to completing: A) An MRI session assessing neural responses to personal smoking/non-smoking environments, standard smoking/non-smoking environments and proximal smoking/non-smoking cues; and B) A laboratory session examining smoking behavior in response to environmental cues.
