DYANAVEL® XR – SMOOTH RELEASE THROUGHOUT
THE DAY

DYANAVEL® XR (amphetamine): After an initial rapid rise in blood levels, a gradual tapering off throughout the day with no additional peaks

Pharmacokinetics (PK) describes the way in which a person’s body absorbs, distributes, metabolizes, and excretes a medication. The PK properties of DYANAVEL XR were studied in healthy adults who were given 7.5 mL (equivalent to 18.8 mg amphetamine base) of DYANAVEL XR compared to 30 mg (equivalent to 18.8 mg amphetamine base) of extended-release (ER) mixed amphetamine salt tablet. Blood samples were collected before and then at several time points after taking the drug. The amount of amphetamine in each sample was then measured in a laboratory.

As shown in the chart below, blood levels of amphetamine increased rapidly after taking DYANAVEL XR, reaching a peak around 4 hours. Levels then gradually decreased from 4 hours through 24 hours.

Blood levels of amphetamine in people who took DYANAVEL XR were compared to those in people who took ER mixed amphetamine salt tablet.
