Subject: Drug Information Update- Review of Therapeutic Equivalence Generic Bupropion XL 300 mg and Wellbutrin XL 300 mg
The Division of Drug Information (DDI) is CDER's focal point for public inquiries. We serve the public by providing information on human drug products and drug product regulation by FDA.
The U.S. Food and Drug Administration received reports of loss of antidepressant effect and new or worsening side effects in some patients who switched from the brand name drug, Wellbutrin XL, used to treat depression, to a generic version of the drug. The FDA reviewed the safety and effectiveness of a generic version, bupropion hydrochloride extended release 300 milligram tablets, manufactured by Impax Laboratories and distributed by Teva Pharmaceuticals. The agency evaluated adverse event reports and other data in order to provide the public with current drug safety information.
The FDA has completed its evaluation of Teva’s version of generic bupropion extended- release tablets, marketed as Budeprion XL 300 milligram. The FDA considers Teva’s generic drug to be a safe and effective choice for consumers in treating depression, as it has been shown to meet all requirements for approval, including bioequivalence to the branded drug, Wellbutrin XL 300 milligram. The FDA’s conclusions can be found in a review of therapeutic equivalence that was released today.
Wellbutrin XL is owned by GlaxoSmithKline,
Budeprion XL is manufactured by Impax Laboratories,
