実験手順

The dissolution of bupropion HBr formulations according to the invention were assessed in three USP-3 media, i.e., SGF pH 1.2, Acetate Buffer pH 4.5 and Phosphate Buffer pH 6.8 over a period of 16 hours. These results are contained in FIG. 66. Particularly Bupropion HBr XL 348 mg tablets (final), Lot # Bup-HBr-XL-012-5; Wellbutrin XL 300 mg tablets (final), Lot # 05A116; Bupropion HBr XL 348 mg tablets ECl Lot # Bup-HBr-XL-012-5 (EC 32 mg wg) and Wellbutrin XL 300 mg tablets (EC10-Lot # 05D047 were assessed in SGF media pH 1.2 for 2 hours, Acetate Buffer pH 4.5 for 2 hours, and Phosphate Buffer SIF pH 6.8 for a total of 10 hours. The results are contained in the FIG. 66-68.
