Zyban for Quitting Smoking

Zyban (Bupropion) is an antidepressant, available as a prescription medicine, that was found helpful for people who wish to quit smoking and it is marketed as one of smoking cessation aids ever since the FDA approved it in 1997. Researchers are not quite sure how does Zyban exactly help people leave cigarettes, but some theorize that it would help balance levels of serotonin, norepinephrine and neurotransmitters dopamine in the brain, thus making the symptoms of withdrawal and the craving for cigarettes less severe.

  • How Effective is Zyban?
    Zyban would be as effective as some nicotine replacement therapy for helping smokers leave cigarettes. Approximately, twice as many smokers are able to give up smoking after about one year of taking Zyban than those who didn’t take anything. If you take Zyban together with some nicotine replacement therapy, you would have even better chances to stop smoking.

Chantix for Quitting SmokingĀ 

Chantix (Varenicline) is one of the FDA-approved prescription medications and it is used for treating smoking addiction. It comes as pills which should be taken twice a day. Chantix can reduce withdrawal symptoms because it can bind to nicotine receptors in your brain and trigger some of those rewarding effects that you get from nicotine. The drug would also prevent nicotine from activating these receptors, so its users would be less likely to get some of the effects of nicotine that they may be missing, in case they relapse.

  • How Effective is Chantix?
    This drug is considered to be one of the best ways for leaving cigarettes for adults (18 and older). Clinical studies have shown that approximately 22% of participants, who have taken Chantix, actually abstained from smoking after a year. A 2006 report from the JAMA (Journal of the American Medical Association) came to a conclusion that this drug can quadruple a smoker’s likelihood of giving up cigarettes.
