Oral lisdexamfetamine dimesylate (Vyvanse® ; lisdexamfetamine), a prodrug of dextroamfetamine, is currently the only drug to be approved in the USA for the treatment of moderate to severe binge eating disorder (BED) in adult patients. Its approval was based on the results of two pivotal short-term (12 weeks) phase III studies, which showed a significantly greater reduction in binge eating days/week at the end of the study with lisdexamfetamine 50-70 mg/day than with placebo. The findings of these studies have been supported and extended by the results of longer-term (≤ 52 weeks) phase III studies, including one with a randomized 26-week withdrawal phase, which showed that lisdexamfetamine markedly reduced the risk of BED relapse relative to placebo...

Lisdexamfetamine dimesylate (LDX) is the first prodrug stimulant used for the treatment of attention-deficit/hyperactivity disorder (ADHD) dosed once daily. Due to its long-acting properties, LDX remains pharmacologically inactive until an enzymatic process predominantly associated with red blood cells converts it to the active ingredient, d-amphetamine and the amino acid lysine. The efficacy of LDX over placebo has been demonstrated in several studies in adults with moderate to severe ADHD with significant improvements noted in ADHD rating scales, Clinical Global Improvement scores, and assessments of executive function, for all doses of LDX (30-70 mg daily)...

Stimulant treatment is highly effective in mitigating symptoms associated with attention-deficit/hyperactivity disorder (ADHD), though the neurobiological underpinnings of this effect have not been established. Studies using anatomical magnetic resonance imaging (MRI) in children with ADHD have suggested that long-term stimulant treatment may improve symptoms of ADHD in part by stimulating striatal hypertrophy. This conclusion is limited, however, as these studies have either used cross-sectional sampling or did not assess the impact of treatment length on their dependent measures...

BACKGROUND AND OBJECTIVES: Attention deficits are often among the most persistent and debilitating impairments resulting from traumatic brain injury (TBI). This study examined the effects of lisdexamfetamine dimesylate (Vyvanse) in treating attention deficits due to moderate-to-severe TBI. It was the first study of lisdexamfetamine dimesylate with this population and, in fact, was the first controlled trial in this area examining a stimulant medication option other than methylphenidate...

BACKGROUND: In clinical practice, α₂-adrenoceptor agonists have been adjunctively administered with psychostimulants for the treatment of attention-deficit/hyperactivity disorder (ADHD). Two studies have examined the adjunctive use of guanfacine extended release (GXR, Intuniv®; Shire Development LLC, Wayne, PA, USA) with psychostimulants in children and adolescents with a suboptimal response to psychostimulant treatment. However, the potential for pharmacokinetic drug-drug interactions (DDIs) between GXR and lisdexamfetamine dimesylate (LDX, Vyvanse®; Shire US LLC, Wayne, PA, USA) has not been thoroughly evaluated...

The beneficial effects of pharmacotherapy on children with attention-deficit hyperactivity disorder (ADHD) are well documented. We use near-infrared spectroscopy (NIRS) methodology to determine reorganization of brain neurovascular properties following the medication treatment. Twenty-six children with ADHD (ages six through 12) participated in a modified laboratory school protocol to monitor treatment response with lisdexamfetamine dimesylate (LDX; Vyvanse®, Shire US Inc.). All children refrained from taking medication for at least two weeks (washout period)...

A 6-year-old girl displayed symptoms of serotonin syndrome after accidental ingestion of Vyvanse (lisdexamfetamine dimesylate). Dexmedetomidine was administered because of persistent neuromuscular hyperactivity and severe agitation despite initial therapy with benzodiazepines. Some children show a paradoxical reaction to benzodiazepines, and dexmedetomidine has a possible role in the treatment of serotonin syndrome.

INTRODUCTION: Psychostimulants (methylphenidate and amphetamines) are the drugs of first choice in the pharmacological treatment of children and adolescents with attention deficit hyperactivity disorder (ADHD). OBJECTIVE: We summarize the pharmacological characteristics of amphetamines and compare them with methylphenidate, special emphasis being given to a comparison of effects and side effects of the two substances. Finally, we analyze the abuse and addiction risks...

Lisdexamfetamine mesylate (Vyvanse(®)) is a novel prodrug approved for attention deficit hyperactivity disorder (ADHD). It is metabolised to d-amfetamine and l-lysine. In drug-experienced humans, lisdexamfetamine evoked lower "Drug liking" scores on Drug Rating Questionnaire (DRQ) scales than immediate-release (IR) d-amfetamine. This study investigated why lisdexamfetamine may have lower abuse potential and a better therapeutic window than d-amfetamine. We compared the pharmacokinetic/pharmacodynamic relationships of lisdexamfetamine and IR d-amfetamine in freely-moving rats by measuring simultaneously extracellular concentrations of striatal dopamine, plasma concentrations of d-amfetamine and lisdexamfetamine, and locomotor activity...

The brain reward system consists of extensive neural pathways that mediate reward behavior such as pleasure and motivation. These pathways may be involved in the development of symptoms such as apathy, anhedonia, and cognitive dysfunction seen in patients with major depression. These pathways are served primarily, although not exclusively, by the chemical neurotransmitter dopamine, which has suggested a therapeutic role for drugs that influence dopamine activity. A small number of clinical trials using various dopaminergic and stimulant drugs for the treatment of major depression and bipolar depression have demonstrated some benefit when combined with standard antidepressant drugs...

The current pharmacotherapy for attention-deficit hyperactivity disorder (ADHD) is mainly based on the stimulant methylphenidate and to a small extent on amphetamines which are not approved in Germany. The only approved non-stimulant so far is atomoxetin (Strattera®), a norepinephrine reuptake inhibitor. There is no approved pharmacotherapy for adults. The aim of the available medication is a reduction of impulsivity, hyperactivity, and attention deficits. Neurobiological correlates of these effects are still not fully understood, however, a functional implication of dopaminergic and noradrenergic systems is known...

We describe here the case of an adolescent who developed eosinophilic hepatitis during treatment for attention-deficit/hyperactivity disorder with lisdexamfetamine dimesylate (Vyvanse [Shire US Inc, Wayne, PA]). A 14-year-old boy presented to his primary care provider with abdominal pain and worsening jaundice. A diagnosis of hepatitis was made with biochemical markers, but evaluation failed to provide an etiology. Worsening hepatitis prompted hospitalization and initiation of steroids for presumed autoimmune hepatitis...
