Propranolol + Nicotine Patch for Smoking Addiction
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests how combining a nicotine patch with propranolol, a beta-blocker, affects smokers' brains and behavior when they encounter smoking triggers. The goal is to understand how these treatments work together and separately to influence the desire to smoke. Participants will not need to quit smoking during the trial. The trial seeks individuals who have smoked at least five cigarettes a day for over a year and can easily identify four places where they typically smoke each week. As a Phase 4 trial, this research aims to understand how these FDA-approved treatments can benefit more patients.
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.
What is the safety track record for these treatments?
Research has shown that propranolol is usually safe for use. In one study involving 52 male smokers, a single dose of propranolol revealed no major safety issues. Propranolol often helps alleviate symptoms like irritability when quitting smoking.
The nicotine patch is also considered safe. Studies indicate it is generally well-tolerated for long-term use and helps ease withdrawal symptoms by providing a steady amount of nicotine without smoking.
When propranolol and the nicotine patch are used together, a study with 73 participants found no major safety concerns. This suggests that using these treatments together is likely safe for a short time. However, these treatments in the trial are not intended for long-term use or smoking cessation. Participants will only use them briefly.12345Why are researchers enthusiastic about this study treatment?
Researchers are excited about these treatments for smoking addiction because they explore a novel combination approach. Unlike standard treatments like nicotine replacement therapy or medications like varenicline, this trial combines propranolol, a beta-blocker typically used for heart issues, with nicotine patches. This combination is unique because propranolol may help reduce the anxiety and stress associated with quitting smoking, potentially making it easier for individuals to stick with their quit plan. By targeting both the physical cravings and the emotional challenges of quitting, this approach could offer a more comprehensive solution for those struggling with smoking addiction.
What evidence suggests that this trial's treatments could be effective for smoking addiction?
Research has shown that nicotine patches, one of the treatments in this trial, can help people quit smoking. Smokers using the real patch are more than twice as likely to quit compared to those using a fake patch. However, the patch's effectiveness can decrease over time, with about 20% of people remaining smoke-free at six months and 9% at a year.
For propranolol, another treatment option in this trial, studies suggest it might reduce cravings and the desire to smoke by altering how the brain reacts to smoking triggers. However, it does not significantly increase the chances of quitting smoking on its own. This trial will test the combination of propranolol with nicotine patches, as well as each treatment individually, to evaluate their effectiveness in helping participants quit smoking.15678Who Is on the Research Team?
