Schizophrenia lisdexamfetamine

BACKGROUND: cocaine craving is a core feature of cocaine use disorder and remains a critical challenge for abstinence and relapse prevention. This review summarizes the anti-craving efficacy of pharmacotherapies tested for cocaine use disorder, in the context of randomized-controlled clinical trials. OBJECTIVES: we assessed the databases of the U.S. National Library of Medicine, Google Scholar, and PsycINFO, without date restrictions up to August 2022, to identify relevant studies...

Schizophrenia (SCZ) treatment is essentially limited to the use of typical or atypical antipsychotic drugs, which suppress the main symptoms of this mental disorder. Metabolic syndrome is often reported in patients with SCZ under long-term drug treatment, but little is known about the alteration of lipid metabolism induced by antipsychotic use. In this study, we evaluated the blood serum lipids of a validated animal model for SCZ (Spontaneously Hypertensive Rat, SHR), and a normal control rat strain (Normotensive Wistar Rat, NWR), after long-term treatment (30 days) with typical haloperidol (HAL) or atypical clozapine (CLZ) antipsychotics...

The etiology of schizophrenia is poorly understood and two principle hypotheses have dominated the field. Firstly, that subcortical dopamine function is enhanced while cortical dopamine function is reduced and secondly, that cortical glutamate systems are dysfunctional. It is also widely accepted that currently used antipsychotics have essentially no impact on cognitive deficits and persistent negative symptoms in schizophrenia. Reduced dopamine transmission via dopamine D1 receptors in the prefrontal cortex has been hypothesized to be involved in the aetiology of these symptom domains and enhancing cortical dopamine transmission within an optimal window has been suggested to be potentially beneficial...

To assess the safety and pharmacokinetics of lisdexamfetamine dimesylate (LDX), a d-amphetamine prodrug, this double-blind study enrolled adults with clinically stable schizophrenia who were adherent (≥12 weeks) to antipsychotic pharmacotherapy. The participants received placebo or ascending LDX doses (50, 70, 100, 150, 200, and 250 mg) daily for 5 days at each dose (dose periods, 1-6; days, 1-5). Of the 31 enrolled participants, 27 completed the study (placebo, n = 6; LDX, n = 21). Treatment-emergent adverse events (AEs) were reported by 4 participants receiving placebo and by 23 participants receiving LDX (all doses) with no serious AEs while on active treatment...

Psychostimulants play a central role in the management of ADHD. Here we review the evidence pertaining to the use of methylphenidate, dexamphetamine and related amphetamine salts, the prodrug lisdexamfetamine and modafinil for the management of comorbid ADHD and non-ADHD indications. There is a growing consensus that stimulant medications are helpful at improving the emotional dysregulation and lability, and oppositional and conduct symptoms that are often associated with ADHD. There is some evidence that psychostimulants may improve outcomes in those with treatment resistant depression, reduce negative symptoms and improve cognitive performance in schizophrenia, and that methylphenidate may reduce binge eating in those with bulimia nervosa...

Negative symptoms of schizophrenia (NSS), related to hypodopaminergic activity in the mesocortical pathway and prefrontal cortex, are predictive of poor outcomes and have no effective treatment. Use of dopamine-enhancing drugs (eg, psychostimulants) has been limited by potential adverse effects. This multicenter study examined lisdexamfetamine dimesylate (LDX), a d-amphetamine prodrug, as adjunctive therapy to antipsychotics in adults with clinically stable schizophrenia and predominant NSS. Outpatients with stable schizophrenia, predominant NSS, limited positive symptoms, and maintained on stable atypical antipsychotic therapy underwent a 3-week screening, 10-week open-label adjunctive LDX (20-70 mg/day), and 4-week, double-blind, randomized, placebo-controlled withdrawal...

OBJECTIVE: Therapeutic goals for chronic mental disorders like major depressive disorder (MDD) and schizophrenia have evolved in parallel with the growing medical knowledge about the course and treatment of these disorders. Although the knowledge base regarding the clinical course of ADHD, a chronic psychiatric disorder, has evolved beyond symptomatic improvement and short-term treatment response, long-term goals, such as functional remission, have not yet been clearly defined. METHOD: A PubMed literature search was conducted to investigate the therapeutic goals of pharmacologic treatment referenced in the published literature from January 1998 through February 2010 using the following commonly used ADHD treatments as keywords: amphetamine, methylphenidate, atomoxetine, lisdexamfetamine, guanfacine, and clonidine...
