Mental Health Home > Bupropion SR
People who suffer from depression or have problems quitting smoking may benefit from bupropion SR. The medication works by helping to block the reuptake of two chemicals in the brain, norepinephrine and dopamine. Most people tolerate the drug well, and even when side effects occur, they are usually minor. Some side effects include nausea, dizziness, and insomnia.
What Is Bupropion SR?Bupropion SR (Wellbutrin SR® or Zyban®) is a prescription medicine used for the treatment of depression (also known as major depression or clinical depression). It is also used for smoking cessation (to help people stop smoking). Bupropion SR is a "sustained-release" version of bupropion, which means that it is long-acting. Wellbutrin SR and Zyban are similar medications, except that Wellbutrin SR is approved for depression, while Zyban is approved for smoking cessation.
Who Makes It?Wellbutrin SR and Zyban are manufactured by GlaxoSmithKline. Generic bupropion SR is made by several manufacturers.
How Does Bupropion SR Work?Bupropion SR is a norepinephrine and dopamine reuptake inhibitor, or NDRI for short. NDRIs affect specific chemicals within the brain known as norepinephrine and dopamine. These are two of several chemicals used to send messages from one nerve cell to another.
- Wellbutrin® (bupropion hydrochloride), a short-acting version, taken three or four times a day
- Wellbutrin XL®, Forfivo™ XL (bupropion XL), or Budeprion XL®, taken once a day
- Aplenzin™ (bupropion hydrobromide), taken once a day.
