Figure 2.

Effect of protease inhibitor cocktail and BNPP on d-amphetamine production from LDX in whole blood or cytosolic extract.

Notes: Data for d-amphetamine are presented as the mean of two replicates, with error bars showing SEM. Points without visible error bars have SEMs smaller than the height of the data point marker. Values for intact LDX remaining at 4 hours are expressed as percentages of the mean LDX concentration at 0 hours.

Abbreviations: BNPP, bis(4-nitrophenyl)phosphate; LDX, lisdexamfetamine dimesylate; SEM, standard error of the mean.
