Generic Wellbutrin XL
Although the first patent for Wellbutrin XL doesn't expire until 2018, a United States District Court ruled that generic Wellbutrin XL could be made. The FDA has assigned an "AB" rating to the generic version, which means that it is considered equivalent to the brand-name version, although it may have different inactive ingredients.
An Overview of Generic Wellbutrin XLWellbutrin XL® (bupropion XL) is a prescription medicine used for the treatment of depression (also known as major depression or clinical depression). It is also used to prevent seasonal affective disorder (SAD).
Wellbutrin XL was first manufactured by GlaxoSmithKline. The first patent expires in 2018. However, it was questionable if this patent could prevent generic Wellbutrin XL from being made, and there have been several lawsuits surrounding this issue. In 2006, a U.S. District Court ruled in favor of a generic manufacturer, essentially deciding that generic Wellbutrin XL could be made.
Names and Strengths of the Generic VersionsGeneric Wellbutrin XL tablets are available in the following strengths:
• Bupropion XL 150 mg tablets
• Bupropion XL 300 mg tablets.
Generic manufacturers may choose to use a standard generic name or create their own name. One maker of generic Wellbutrin XL has chosen to create its own name: Budeprion XL®. Although initially available in both strengths, the 300-mg strength of Budeprion XL was withdrawn from the market in 2012 after it was shown not to be equivalent to Wellbutrin XL (it is not absorbed as well). Other versions of the 300-mg generic are still available.
