confusion about generics for bupropion (Wellbutrin, Zyban, Budeprion, Buproban, etc)

Please see the FDA's October 2012 update regarding Budeprion XL 300 mg not being equivalent to Wellbutrin XL 300 mg

There's lots of confusion about generics for bupropion (Wellbutrin, Zyban, Budeprion, Buproban, etc).

It's hard to keep track of which ones are equivalent since some generics have their own "brand names" or use different drug suffixes.

The Orange Book adds to the confusion. It lists all the long-acting generics as "extended-release" instead of "SR" or "XL" like Wellbutrin. This makes it hard to tell which ones are appropriate for once- or twice-daily dosing.
