Propranolol + Nicotine Patch for Smoking Addiction
What You Need to Know Before You Apply
What is the purpose of this trial?
This study is designed to investigate the effects of a beta-adrenergic antagonist (Propranolol; 40 mg IR) and nicotine patch (14 mg) administered alone and in combination on neurobiological and behavioral responses to smoking cues in ongoing cigarette smokers. This is a basic experimental study in humans and participants will not take these medications for an extended period or make a cessation attempt as part of their involvement in this research project.
Will I have to stop taking my current medications?
Yes, you will need to stop taking any psychoactive medications, smokeless tobacco, smoking cessation medications, nicotine products, beta-adrenergic medications, or other blood pressure medications to participate in this trial.
Is the combination of propranolol and nicotine patch safe for humans?
Propranolol has been studied for its effects on memory and craving in smokers, showing it can decrease craving without significant safety concerns. Nicotine patches, like Nicoderm, have been used safely to help people quit smoking, although they can cause side effects like skin irritation. Overall, both treatments have been used safely in humans, but combining them specifically for smoking addiction needs more research to confirm safety.12345
How does the drug propranolol combined with a nicotine patch differ from other smoking addiction treatments?
The combination of propranolol, a beta-blocker typically used for heart conditions, with a nicotine patch is unique because it attempts to address both the physical addiction to nicotine and the stress or anxiety associated with quitting smoking. However, previous studies have shown that propranolol alone does not significantly help people stop smoking, making this combination a novel approach.678910
What data supports the effectiveness of the treatment Propranolol + Nicotine Patch for smoking addiction?
The study on labetalol, a similar type of drug to propranolol, showed that it could help reduce withdrawal symptoms when combined with nicotine replacement therapy. This suggests that propranolol might also help when used with nicotine patches, although more research is needed to confirm this.26111213
