Zyban (Bupropion Hydrochloride) - Summary



ZYBAN (bupropion hydrochloride) Sustained-Release Tablets are a non-nicotine aid to smoking cessation. ZYBAN is chemically unrelated to nicotine or other agents currently used in the treatment of nicotine addiction. Initially developed and marketed as an antidepressant (WELLBUTRIN® [bupropion hydrochloride] Tablets and WELLBUTRIN SR® [bupropion hydrochloride] Sustained-Release Tablets), ZYBAN is also chemically unrelated to tricyclic, tetracyclic, selective serotonin re-uptake inhibitor, or other known antidepressant agents. Its structure closely resembles that of diethylpropion; it is related to phenylethylamines. It is (±)-1-(3-chlorophenyl)-2-[(1,1-dimethylethyl)amino]-1-propanone hydrochloride.

ZYBAN is indicated as an aid to smoking cessation treatment.

Published Studies Related to Zyban (Bupropion)

Interactions between bupropion and 3,4-methylenedioxymethamphetamine in healthy subjects. [2015]
3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is a popular recreational drug. The aim of the present study was to explore the role of dopamine in the psychotropic effects of MDMA using bupropion to inhibit the dopamine and norepinephrine transporters through which MDMA releases dopamine and norepinephrine by investigating.

Bupropion in adults with Attention-Deficit/Hyperactivity Disorder: a randomized, double-blind study. [2014]
Attention-Deficit/Hyperactivity Disorder is one of the most common mental disorders in childhood, and it continues to adulthood without proper treatment. Stimulants have been used in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) for many years, and the efficacy of methylphenidate in the treatment of adults with ADHD has been proven to be acceptable according to meta-analysis studies.

Zyban as an Effective Smoking Cessation Aid for Patients Following an Acute Coronary Syndrome: The ZESCA Trial [Recruiting]
Patients who continue to smoke after a heart attack have a 35% increased risk of a recurrent event or death compared with those who quit. Many patients attempt to stop smoking after a heart attack, but relapse rates approach 66%. A variety of smoking cessation aids have been shown to be effective for the general population. However, bupropion is the only non-nicotine replacement therapy shown to improve abstinence rates in healthy young smokers. Furthermore, nicotine replacement therapies (NRTs) are contraindicated in the immediate period following a heart attack because of the undesirable effects of nicotine. Although bupropion has been successfully used to reduce smoking rates in healthy young populations, its efficacy and safety in the setting of patients recovering from an ACS is unknown. These patients, if they continue to smoke, are at exceptionally high risk for recurrent cardiac events. If bupropion is effective in this population, it will have a major impact on secondary prevention of recurrent clinical events in patients who suffer a heart attack.

The Effect of Varenicline (Chantix) and Bupropion (Zyban) on Smoking Lapse Behavior [Recruiting]
The purpose of this study is to examine how smoking cessation medications (varenicline, bupropion) affect the ability to resist smoking and also subsequent ad-lib smoking in non-treatment seeking daily smokers.

Concurrent Bupropion / Varenicline for Smoking Cessation [Recruiting]
This study focuses on the first step in developing an algorithm for maximizing quit-smoking success based on an adaptive approach, which changes treatment from the initial NRT (nicotine replacement therapy) when that treatment alone may not be sufficient. These NRT "non-responders" are switched (in double-blind fashion) before the quit date to receive either varenicline (Chantix) alone or varenicline (Chantix) paired with bupropion (Zyban). Some participants who would otherwise have failed at their quit smoking attempt could be "rescued" by switching to alternative pharmacotherapies. The proposed study will evaluate the combination treatment against varenicline alone in an adaptive trial design

Evaluation of a Tailored Smoking Cessation Treatment Algorithm Based on Initial Treatment Response and Genotype [Recruiting]
Nicotine replacement therapy (NRT) is a well-tolerated and efficacious smoking cessation treatment, and yet many smokers fail to quit using NRT. Many of these smokers may benefit from prescription treatment alternatives, including Zyban or Chantix. In this study, the investigators propose to develop and evaluate a stepped-care treatment algorithm that would evaluate whether smokers who receive treatment with NRT should be supplemented with Zyban or switched to Chantix only based on: 1) their initial response to NRT; and 2) individual genetic factors found to predict smoking cessation in other studies evaluating these treatments. This study is a continuation of our previous studies showing that abstinence rates can be increased by starting nicotine patch therapy two weeks before the quit date. The investigators will provide pre-cessation NRT to all participants initially. Those who do not show a favorable response on early indicators of success (e. g., smoking in the first week after the target quit-smoking date) will receive "rescue" treatment by having their NRT treatment supplemented with Zyban , by being switched to treatment with Chantix or will remain on NRT (control).

The investigators hypothesize that "Rescue" treatment with Zyban in combination with NRT or Chantix will increase success rates over leaving subjects on NRT when they are NRT insufficient responders, i. e. they have shown an unfavorable response to NRT in the first week pre-quit or the first week post-quit.

Zyban review by 38 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Mild Side Effects
Treatment Info
Condition / reason:   Smoking Cessation
Dosage & duration:   150mg taken twice daily for the period of 4 Months
Other conditions:   None
Other drugs taken:   Birth Control
Reported Results
Benefits:   The drug did exactly what it was supposed to do. It completely eliminated all nicotine cravings leaving only the psychological aspect to worry about. So if I kept myself busy, the thought of smoking would never even enter my mind.
Side effects:   For the first week or so, I was slightly hyperactive and had some trouble sleeping. That problem went away with some adjustment in the time I took the drug as well as with my bodies assimilation of the drug. I also had a mildly bad taste in my mouth. That too faded away.
Comments:   I expressed to my doctor a desire to try this drug to quit smoking. She prescribed it to me and I began taking it shortly thereafter. Before my 2 week quit date had even arrived, I noticed a marked decrease in nicotine withdrawl episodes. I just didn't need to smoke. I found I was started to smoke only when I thought I "should" - after dinner, right before bed and other habitual times. Once I stopped smoking all together, it was a relief to only have to battle my habits and not the withdrawl effects of nicotine as well.

Zyban review by 28 year old female patient

Overall rating:  
Effectiveness:   Ineffective
Side effects:   Extremely Severe Side Effects
Treatment Info
Condition / reason:   to quit smoking
Dosage & duration:   don't recall (dosage frequency: 1 per day) for the period of 10 days
Other conditions:   none
Other drugs taken:   none
Reported Results
Benefits:   none
Side effects:   My side effects were severe depression, and alteration in personality. Do not take this drug, the side effects can be severe. I had no previous issues with depression, and as soon as I started taking this drug, I developed severe depression, and changes in my personality. Thankfully, my family noticed a change, and advised me and told me to stop taking Zyban. It took 2 years to overcome the depression and over 3 years to begin to feel like myself again. Stay away from this drug! If you want to quit smoking, butt out and stick to your guns. I quit, and it wan't the Zyban. I have been smoke free for 10 years, and depression free for 7 or 8. Someone should consider a class-action suit against the company which produces this drug. Based on other reviews I have seen, I am not the only one who had these side effects.
Comments:   I took this drug to quit smoking. I am a female and was 28 years old at the time.
