Brand-name and generic bupropion tablets are available in three forms, each as the hydrochloride salt: immediate release (Wellbutrin), sustained release (Wellbutrin SR), and extended release (Wellbutrin XL or XR). "Sustained release" and "extended release" are generally interchangeable terms, but in this case Wellbutrin SR is intended for twice-daily dosing and Wellbutrin XL is intended for once-daily dosing. Not all generics have retained this naming scheme, and the United States Pharmacopeia requires all prolonged-release drug formulations (including generics for Wellbutrin SR) to be labeled "extended release", which has caused confusion and medication errors.[106][107] According to GlaxoSmithKline, a 150 mg Wellbutrin SR tablet can be split in two and retain its sustained-release characteristics.[108]
