International Nonproprietary Name (INN)
The generic name for Wellbutrin SR is "bupropion." This medication is primarily classified as an antidepressant and is used mainly for treating major depressive disorder (MDD). Bupropion works differently compared to other antidepressants, such as selective serotonin reuptake inhibitors (SSRIs). It affects neurotransmitters in the brain, particularly norepinephrine and dopamine, which are associated with mood regulation.
Brand Names in Canada
In Canada, the well-known brand for bupropion is Wellbutrin SR, a sustained-release formulation. Another brand commonly prescribed is Zyban, which is often used for smoking cessation. Both these brands are marketed by GlaxoSmithKline, a significant player in the pharmaceutical industry.
ATC Code and Classification
The ATC code for bupropion is N06AX12. This code indicates that bupropion is classified within the category of psychoanaleptics, particularly as "other antidepressants." The categorization highlights its role in broader mental health management, distinguishing it from typical SSRI and SNRI antidepressants.
Dosage Forms
Bupropion is available in various dosage forms, primarily in tablet form. The typical strengths available include:
- 100mg
- 150mg
- 200mg
Specifically, the sustained-release (SR) and extended-release (XL) versions allow for different dosing schedules tailored to patient needs. Immediate-release preparations are also less commonly available, primarily reserved for specific conditions. Typically, medications are supplied in blister packs or pharmacy vials.
Manufacturers
Besides GlaxoSmithKline, which was the original manufacturer of Wellbutrin, other pharmaceutical companies producing generic versions of bupropion include Teva, Mylan, and Dr. Reddy's. These organizations ensure that bupropion remains accessible to patients across Canada and other markets.
Registration Status
Health Canada has approved Wellbutrin and Zyban for the treatment of major depressive disorder and for smoking cessation, respectively. Regulatory recognition indicates these formulations have undergone rigorous safety and efficacy evaluations. Internationally, organizations such as the FDA and EMA also endorse these applications, although bupropion remains a prescription-only medication in most regions.
Dosage & Administration
When it comes to medication like Wellbutrin SR, understanding the dosage and administration is crucial for achieving the best results. Here's the scoop on typical dosages for various conditions.
| Condition | Starting Dose | Maintenance Dose | Max Daily Dose |
|---|---|---|---|
| MDD (major depressive disorder) | 150mg once daily | 150mg twice daily (sustained-release) | 400mg (sustained-release) |
| Seasonal Affective Disorder | 150mg once daily (morning) | 150-300mg/day (sustained or extended-release) | 400mg (sustained-release) |
| Smoking Cessation (as Zyban) | 150mg once daily (first 3 days) | 150mg twice daily | 300mg |
Adjustments
Certain factors might necessitate dosage adjustments.
- **Elderly patients** should start at the lower end of the dosage spectrum to monitor tolerability, especially for hypertension or seizures.
- **Renal impairment** may require a reduced frequency or lower dose due to accumulation risks.
- **Hepatic impairment** also demands caution, often needing decreased doses or extended dosing intervals to mitigate toxicity.
Treatment Duration
Typically, an initial response to Wellbutrin SR can be expected within 6 to 8 weeks, followed by a maintenance phase often extending from 6 to 12 months or longer based on clinical judgement. For smoking cessation, a regimen generally lasts between 7 and 12 weeks, with possible extensions for ongoing support.
Safety & Warnings
Understanding the safety profile of Wellbutrin SR helps in making informed decisions. Absolute contraindications include a history of seizures or eating disorders like bulimia. Use with caution in individuals with a history of head trauma or high blood pressure.

User Feedback
Social media forums reveal common themes: people often express challenges with waiting for effects to kick in, and the occasional side effects like insomnia and dry mouth do cause concern.

Alternatives & Comparison
When considering treatment options for depression, it's important to know that Wellbutrin SR is just one of several antidepressants available. In Canada, many individuals are prescribed SSRIs (Selective Serotonin Reuptake Inhibitors) and SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors) as alternatives. Common examples include:
- Fluoxetine (Prozac)
- Sertraline (Zoloft)
- Duloxetine (Cymbalta)
- Venlafaxine (Effexor)
Each of these medications works differently, with unique benefits and potential side effects. Some patients prefer these options for their varied mechanisms of action and different side effect profiles.
| Medication | Average Price (CAD) | Effectiveness | Safety Profile |
|---|---|---|---|
| Wellbutrin SR | $130/month | High | Seizure risk, mild |
| Fluoxetine | $85/month | Moderate | Generally safe, possible weight gain |
| Duloxetine | $110/month | High | Nausea, possible hypertension |
Local physicians often have specific preferences when prescribing these medications. Many tend to choose SSRIs first, due to their long-standing track record and well-understood side effect profiles. Others may opt for SNRIs or Wellbutrin SR, especially when dealing with patients requiring additional efficiency in relation to energy levels or sexual side effects linked to SSRIs. These insights help shape patient-centered treatment decisions in everyday practice.
