Brief Summary: The purpose of this study is to evaluate the safety and effectiveness of NRP104 administered as a daily morning dose (30, 50, and 70mg/day) compared to placebo in adults (18-55 years of age inclusive) diagnosed with moderate to severe Attention Deficit Hyperactivity Disorder (ADHD).

* functioning at age appropriate levels intellectually
* blood pressure measurements within the 95th percentile for their gender, height and age
* ECG results are within the normal range

Exclusion Criteria:

* comorbid psychiatric diagnosis (such as psychosis, bipolar illness, pervasive developmental disorder, severe obsessive compulsive disorder, severe depressive or severe anxiety disorder) or other symptomatic manifestations

Female participants of childbearing potential must test negative for pregnancy at the time of enrollment based on a urine pregnancy test and agree to use a reliable method of birth control during the study. Females of childbearing potential are defined as women not surgically sterilized and are between menarche and 2 years post-menopause.
4. Must have a satisfactory medical assessment with no clinically significant abnormalities as determined by medical history, physical exam, ECG, and clinical laboratory testing.
5. Must be able to swallow capsules.
6. Must be able to begin the daily dose of study medication in the morning.

5. Participants with hypertension at screening, indicated by a blood pressure reading of 135/90 and heart rate above 120bmp.
6. Female participants of childbearing potential who test positive for pregnancy at the time of enrollment based on a urine pregnancy test, or who do not agree to use a reliable method of birth control during the study.

* Has any comorbid psychiatric diagnosis with significant symptoms such as any severe comorbid Axis II disorders or severe Axis I disorders including Post Traumatic Stress Disorder (PTSD), psychosis, bipolar illness, severe obsessive compulsive disorder, severe depressive or severe anxiety disorder or other symptomatic manifestations that will contraindicate NRP104 treatment or confound efficacy or safety assessments. Specifically, subjects with mild to moderate forms of Axis I disorders including social phobia and dysthymia may be included while subjects with a lifetime history of psychosis or bipolar disorder will be excluded from participation.
