Attention Deficit Hyperactivity Disorder (ADHD) is a neurobiological disorder characterized by lifelong issues of inattention, distraction, organizational difficulties, forgetfulness, restlessness, talking out of turn, difficulty waiting and interrupting others. ADHD is the second most common neuropsychiatric disorder affecting 4.4% of the US adult population, or between 8-9 million individuals (Kessler et al., 2006).
Droxidopa (L-dihydroxyphenylserine (L-DOPS)) is a synthetic catecholamine which is converted to norepinephrine (NE) via decarboxylation, resulting in increased levels of NE centrally in the CNS and peripherally. Co-treatment with carboxylase inhibitors, such as carbidoba, given with droxidopa, can increase the CNS levels of NE with greater crossing of the blood-brain barrier. Droxidopa has received orphan drug approval by the FDA for the treatment of symptomatic neurogenic orthostatic hypotension in individuals with primary autonomic failure. The half-life of droxidopa is approximately 2-3 hours, resulting in administration thee times daily.
As adult ADHD is characterized as a disorder of decreased NE activity in the pre-frontal cortex, it is hypothesized that treating patients with droxidopa (in co-administration of carbidopa) will have a positive effect on adult ADHD.
This will be a 12-week study of twenty enrolled subjects with DSM IV adult ADHD (age 18-55), with a goal of completing twenty subjects in the trial. The primary objective of this study is to determine the effect of droxidopa therapy on adult ADHD symptoms over the course of a six-week open-label titration period followed by a two-week double-blind, placebo-controlled period. The primary outcome measure will be changes from baseline in total score on the Adult ADHD Investigator Symptom Rating Scale (AISRS). Secondary measures will be changes in self-report ADHD symptoms on the ASRS v1.1 Symptom Checklist, global impairment on the Clinician Global Impression Scale (CGI).

A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood. (From DSM-IV)

A methylphenidate derivative, DOPAMINE UPTAKE INHIBITOR and CENTRAL NERVOUS SYSTEM STIMULANT that is used in the treatment of ATTENTION DEFICIT HYPERACTIVITY DISORDER.
A dextroamphetamine drug precursor that also functions as a CENTRAL NERVOUS SYSTEM STIMULANT and DOPAMINE UPTAKE INHIBITOR and is used in the treatment of ATTENTION DEFICIT HYPERACTIVITY DISORDER.
The d-form of AMPHETAMINE. It is a central nervous system stimulant and a sympathomimetic. It has also been used in the treatment of narcolepsy and of attention deficit disorders and hyperactivity in children. Dextroamphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulating release of monamines, and inhibiting monoamine oxidase. It is also a drug of abuse and a psychotomimetic.
