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.

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.

Clinical Trials Related to Zyban (Bupropion)

Study of Lunesta Versus Placebo for Sleep Problems Related to Smoking Cessation and Zyban [Terminated]
Objectives: The primary objective of this study is to determine the efficacy of eszopiclone at treating sleep problems related to withdrawal from nicotine in healthy smokers attempting smoking cessation. Sleep disturbances are a significant problem for smokers who are trying to quit smoking. Smokers may be more likely to have sleep problems and both nicotine withdrawal and agents used to aid smoking cessation (e. g., pharmacotherapies) may disrupt sleep. Lunesta (eszopiclone) is a medication that has been approved by the FDA to treat insomnia. Eszopiclone's efficacy for treating insomnia makes it a promising agent for treating nicotine withdrawal-related symptoms of sleep disturbance. This study will be 7 weeks duration. All participants will begin taking Zyban at the beginning of week 1 and will be asked to try to quit smoking at the beginning of week 2. Participants will also begin to take Lunesta or matched placebo (3 mg qd x 6 weeks) on the target quit date at the beginning of week 2. All subjects will receive eight (8) weekly sessions of brief individual supportive smoking cessation counseling. Hypothesis: It is hypothesized that significantly fewer sleep problems will be reported by participants taking Lunesta as compared to placebo. Specifically, it is expected that participants taking Lunesta will report less difficulty falling and staying asleep, higher sleep quality, and less insomnia-related fatigue and distress than participants taking placebo.

Bupropion Depression [Recruiting]
Determine bioequivalence between branded and generic bupropion extended release (XL) products (and between generic products) at steady state in patients with major depressive disorder.

STOP Study: Effectiveness of Zyban in a Clinical Population [Active, not recruiting]
Despite the significant health, social and economic costs of cigarette smoking, 17% of Ontarians still currently smoke. Use of smoking cessation pharmacotherapy such as Zyban (bupropion HCl) has been shown to double quit rates but such medications are under-utilized by smokers attempting to quit. It has been suggested that the high price of pharmacotherapy may act as a barrier to accessing such treatment. The main objective of this study is to evaluate the methods and effectiveness of providing smokers who want to quit with 8 weeks of free Zyban in combination with smoking cessation counselling through family health teams and community health centres across the province. Hypothesis: Ontario smokers who receive 8-weeks of free bupropion in combination with brief counselling will have higher smoking cessation rates than the standard population cessation rates.

Bupropion for Smoking Cessation During Pregnancy [Recruiting]
This is a prospective, double-blind placebo-controlled randomized controlled trial of the preliminary safety and efficacy of bupropion SR in combination with behavioral counseling for smoking cessation during pregnancy.

Combination Bupropion / Varenicline for Smoking Cessation in Male Smokers [Completed]
Previous results from the investigators' Center have shown that combination treatment with Chantix and Zyban is more successful in helping men quit smoking. The investigators hope to replicate these findings with this study.

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.
