Exclusion Criteria:

1. Current or recurrent disease that could affect the action, absorption or disposition of the investigational products, or could affect clinical or laboratory assessments.

2. Current or relevant previous history of physical or psychiatric illness, any medical disorder that may require treatment or make the subject unlikely to fully comply with the requirements of the study or complete the study, or any condition that presents undue risk from the investigational products or study procedures.

6. History of a seizure disorder (other than infantile febrile seizures), any tic disorder or a current diagnosis and/or known family history of Tourette's Disorder.

7. History of symptomatic cardiovascular disease, advanced arteriosclerosis, structural cardiac abnormality, cardiomyopathy, serious heart rhythm abnormalities, coronary artery disease, transient ischemic attack or stroke or other serious cardiac problems that may place them at increased vulnerability to the sympathomimetic effects of a stimulant drug.

8. History of controlled or uncontrolled hypertension or a resting sitting systolic blood pressure >139mmHg or diastolic blood pressure >89mmHg.

9. Known family history of sudden cardiac death or ventricular arrhythmia.

10. Currently considered a suicide risk, has previously made a suicide attempt or has a prior history of, or is currently demonstrating suicidal ideation.

11. Current use of any medication (including prescription, over the counter [OTC], herbal or homeopathic preparations) with the exception of hormonal replacement therapy or hormonal contraceptives (Current use is defined as use within 14 days of first dose of investigational product).

12. Use of any medication known to inhibit or induce the CYP450 enzymes responsible for the metabolism of the investigational products within 14 days of first dose of investigational product.

13. Known or suspected intolerance or hypersensitivity to the investigational product(s), closely related compounds or any of the stated ingredients.
