Adderall XR, with $111.4 million revenues in the first quarter of 2012, is one of the top revenue grossers at Shire. As per data provided by IMS Health National Prescription Audit, Adderall XR enjoys a 7% share of the US ADHD market. Apart from this, the company has two authorized generic partners - Teva Pharmaceuticals (TEVA) and Impax Laboratories (IPXL). We believe that the entry of additional generic versions of Adderall XR will eat into Adderall XR revenues.
Parents completed a modified version of the BSEQ during each week of the trial. Appetite, stomachaches, and insomnia were rated as worse by parents while children were receiving either dose of Adderall; headaches were rated as worse when children were receiving the higher dose of Adderall. Parents rated certain side effects, including staring/daydreaming, sadness, euphoria, and anxious/irritable, as worse during placebo regimens. Conclusions. We found that Adderall is highly efficacious in our population of youth diagnosed with ADHD. In addition, Adderall is well-tolerated with a side effect profile similar to that reported for other psychostimulants.
In the poor or nonresponder group of 9 patients (38%), all experienced side effects (including a more substantial decrease in appetite, gastrointestinal upset, migraine headache, and heart palpitations; see Table 2), prompting each one to discontinue the Adderall within the first 3 weeks of the trial. Of note, 4 of 7 patients in the study with a comorbid anxiety diagnosis experienced near-immediate symptoms of acute anxiety (including diaphoresis, tremor, shortness of breath, and an impending sense of doom) at the start of Adderall therapy.
While efforts have been made to develop sensitive and specific diagnostic inventories for ADHD in adulthood, the diagnostic process itself often presents the most challenging aspect of the clinical management of adults with this disorder. However, substantial evidence suggests that adult forms of ADHD can be reliably diagnosed and effectively treated
Amphetamines have a high potential for abuse. Administration of amphetamines for prolonged periods of time may lead to drug dependence and must be avoided. Particular attention should be paid to the possibility of subjects obtaining amphetamines for nontherapeutic use or distribution to others, and the drugs should be prescribed or dispensed sparingly.
For doses of Adderall® greater than 5 mg, significant time course effects were observed. Rapid improvements on teacher ratings and math performance were observed by 1.5 hours after administration, and these effects dissipated by the end of the day. The specific pattern of time course effects depended on dose: the time of peak effects and the duration of action increased with dose of Adderall®.
The number of prescriptions for A.D.H.D. medications dispensed for young people ages 10 to 19 has risen 26 percent since 2007, to almost 21 million yearly, according to IMS Health, a health care information company — a number that experts estimate corresponds to more than two million individuals. But there is no reliable research on how many high school students take stimulants as a study aid. Doctors and teenagers from more than 15 schools across the nation with high academic standards estimated that the portion of students who do so ranges from 15 percent to 40 percent.
Adderall is composed of mixed amphetamine salts, which work by increasing the amount of the active neurotransmitters, norepinephrine and dopamine, in the brain. More formally known as Dextroamphetamine, it acts primarily on the DA systems. The primary reinforcing and behavioral-stimulant effects of amphetamine enhance dopaminergic activity, primarily in the mesolimbic dopaminergic pathway.
For those with ADHD, the drug increases alertness, libido and overall cognitive performance, improving mood and stemming fatigue. For the last 15 years, treatment with Adderall has helped significantly improve many lives. But for those who do not have the disorder, the drug, like other powerful amphetamines, causes euphoria, increasing the risk of addiction. According to the CDC, 1 in 12 Americans is diagnosed with ADHD and sales of Adderall have soared more than 30-fold since 2001.
Adderall is a prescription stimulant used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy.
