Phamacology Q: Are SR and XR caps/tabs generally the same?

  1. i think both are the same SR is for sustained release and XR IS FOR EXTENDED RELEASE

  2. From the prescribing info for Wellbutrin:

    “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.
