Study Endpoints

Primary Endpoints

Maximum Plasma Concentration (Cmax) of Lisdexamfetamine Dimesylate
Day 15 and Day 30 (24 hour sampling)

Lisdexamfetamine dimesylate (SPD489) itself is inactive, but following oral administration is converted to the active isomer, d-amphetamine, that is responsible for the drug's therapeutic activity.

Cmax of d-Amphetamine
Day 15 and Day 30 (24 hour sampling)

d-Amphetamine is the active isomer of Lisdexamfetamine dimesylate (SPD489) and is responsible for the drug's therapeutic activity.

Cmax of Venlafaxine Hydrochloride
Day 15 and Day 30 (24 hour sampling)

Venlafaxine Hydrochloride is the active ingredient of Effexor XR

Cmax of o-Desmethylvenlafaxine
Day 15 and Day 30 (24 hour sampling)

Venlafaxine, after oral administration, is metabolized in the liver to an active metabolite, o-Desmethylvenlafaxine.

Cmax of Composite (Venlafaxine + o-Desmethylvenlafaxine)
Day 15 and Day 30 (24 hour sampling)
