Bupropion is the generic name for Wellbutrin [1].
What else is bupropion used for?
Bupropion is prescribed to treat major depressive disorder and seasonal affective disorder. It is also available in a sustained-release formulation (Zyban) for smoking cessation [2].
How does bupropion work?
Bupropion is a norepinephrine-dopamine reuptake inhibitor (NDRI) [3]. This means it increases the levels of norepinephrine and dopamine in the brain, neurotransmitters that play a role in mood regulation and motivation [4].
When does the patent for Wellbutrin expire?
The patent exclusivity for Wellbutrin XL, a specific formulation, expired in 2008. This allowed for the introduction of generic versions [5].
Are there other antidepressants like bupropion?
Other antidepressants work through different mechanisms. For example, selective serotonin reuptake inhibitors (SSRIs) like fluoxetine (Prozac) and sertraline (Zoloft) primarily affect serotonin levels [4]. Monoamine oxidase inhibitors (MAOIs) are another class of antidepressants that inhibit the breakdown of several neurotransmitters [6].
What are the side effects of bupropion?
Common side effects of bupropion can include dry mouth, insomnia, nausea, vomiting, headache, dizziness, and tremors. More serious side effects, though less common, can include seizures, high blood pressure, and allergic reactions [7].
Can bupropion be mixed with other medications?
It is important to discuss all current medications with a healthcare provider before starting bupropion, as it can interact with other drugs, including other antidepressants, MAOIs, and medications that lower the seizure threshold [8]. DrugPatentWatch.com can provide further information on drug patents and exclusivity [9].
