Background: Hypertension is a common complication in injection drug users (IDU), especially a high proportion of resistant hypertension occurs among them. However, the involving mechanisms remain largely unknown. Methods: We here investigated the key signaling moieties in resistant hypertension in drug users. Analyses were performed with high-throughput transcriptomic sequencing data of peripheral blood from individuals with drug-sensitive hypertension (Ctrl-DS), IDU with resistant hypertension (IDU-DR), and IDU with sensitive hypertension (IDU-DS)...

Asymmetric functionalization of the C(sp3 )-H bond is an attractive yet challenging strategy to achieve versatile bond-forming events, enabling the precise assembly of molecular complexity with minimal manipulation of functional groups. Here, we report an asymmetric C(sp3 )-H/C(sp3 )-H umpolung coupling of N -allylimine and coordinating α-aryl carbonyls by using chiral phosphoramidite-palladium catalysis. A wide variety of α-heteroaryl ketones and 2-acylimidazoles are nicely tolerated to open a convenient and tunable avenue for efficient synthesis of enantioenriched β-amino-γ,δ-unsaturated carbonyl derivatives with high levels of regio- and stereoselectivities, capable of providing a key intermediate for asymmetric synthesis of Focalin...

Thomas is a 13-year-old boy with autism spectrum disorder, attention deficit hyperactivity disorder (ADHD), generalized anxiety disorder, separation anxiety disorder, and major depressive disorder who presented for a follow-up to his developmental and behavioral pediatrician (DBP). His mother describes an increase in symptoms of anxiety and depression for the last 6 weeks, accompanied by suicidal ideation and thoughts of self-mutilation.Before this increase in symptoms, he had been doing well for the last several months with the exception of increasing weight gain, and Abilify was decreased from 5 mg to 2...

As postsecondary students' use of "study drugs" becomes more popular with increasingly reported negative effects on health and academic performance, failing prohibitionist policies to reduce consumption, and ambiguity in literature towards best practices to address this population, we present a literature review that seeks effective solutions educational institutions can apply to improve outcomes for students who use drugs. Motivations for use, effects of the substances, an analysis of efforts to control use from educational institutions, and suggestions on promoting most effective outcomes based on harm reduction, are described...

PURPOSE: The aim of this study was to describe trends in attention deficit hyperactivity disorder (ADHD) drugs consumption in Israel (Ritalin, Concerta, Daytrana, Vyvanse, Focalin, and Adderall) over the 8 years, 2005-2012, and to explore explanations for changes in amounts and patterns of the utilization. METHODS: Data for the period from 2005 to 2012 were extracted from the database maintained by the Israel Ministry of Health's Pharmaceutical Administration...

PURPOSE: Investigate the performance of partial area under the drug concentration-time curve (PAUC) metrics (0-3 h) and (3-24 h), for Concerta, Ritalin LA and Focalin XR (different Methylphenidate modified-release formulations). The metrics have been chosen as additional BE metrics for Ritalin LA by the FDA to establish BE for these products due to the early and late peak concentrations critical for treatment of morning and afternoon symptoms of attention deficit hyperactivity disorder (ADHD)...

OBJECTIVE: The non-medical use of prescription drugs (NMUPD) among youth is a significant public health concern, ranking as the second most frequently used class of drug in youth after marijuana. Given the complex and multiple pathways that may lead to NMUPD in youth, this study examines predictors of NMUPD across constitutional, psychological, and family/peer domains. METHOD: An ethnically diverse sample of 6790 youth in the 6th-12th grades enrolled in public schools throughout Mississippi completed a battery of questionnaires as part of a broader school-based mental health screening initiative in Mississippi (Behavioral Vital Signs Project)...

Pharmacotherapy, one of the effective modalities of treatment for attention deficit/hyperactivity disorder (ADHD), was discovered serendipitously and, until recently, consisted primarily of short-acting methylphenidate and dextroamphetamine compounds. The US Food and Drug Administration's (FDA) approval of Concerta in 2000 followed by approval of additional long-acting methylphenidate (Ritalin LA; Metadate CD) and amphetamine formulations (Adderall XR) expanded the repertoire. By providing sustained efficacy for most of the school day, mid-day administration is avoided, privacy is preserved, and adherence to treatment improves...

Dexmethylphenidate extended release (XR) [Focalin XR] is a CNS stimulant indicated for the treatment of attention-deficit hyperactivity disorder (ADHD) in patients aged > or = 6 years. Dexmethylphenidate contains the d-threo-enantiomer of methylphenidate. Dexmethylphenidate XR capsules have a bimodal release profile, which mimics two doses of dexmethylphenidate immediate release (IR) given 4 hours apart, and allows once-daily administration. Once-daily dexmethylphenidate XR was effective and generally well tolerated in the treatment of ADHD in children, adolescents and adults in placebo-controlled trials...

OBJECTIVE: This 5-week, multicenter, double-blind, placebo-controlled, parallel-group investigation is the first fixed-dose study to evaluate efficacy and tolerability of three doses of (10, 20, or 30 mg, once daily [o.d.]) dexmethylphenidate hydrochloride (HCl) extended-release (d-MPH XR; Focalin XR) across multiple settings to treat pediatric attention-deficit/hyperactivity disorder (ADHD). RESULTS: ADHD pediatric outpatients (n = 253) diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, 4(th) edition, criteria were randomized (1:1:1:1) to receive d-MPH XR (10, 20, or 30 mg o...

OBJECTIVE: To review recent literature on the different stimulant preparations regarding efficacy and safety in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and describe advantages and disadvantages of the many available dosage formulations. DATA SOURCES: Literature retrieval was performed through PubMed/MEDLINE (2005-December 2008) using the terms methylphenidate, amphetamines, central nervous system stimulants, and attention-deficit/hyperactivity disorder...

Attention-deficit/hyperactivity disorder (ADHD) is associated with impairments in educational, occupational, neuropsychological, and social functioning in adults. Successful diagnosis and treatment of the disorder in adults can be a challenge because recent and integrative clinical guidelines are lacking and diagnostic criteria are based on making a retrospective diagnosis of childhood-onset ADHD. To develop evidence-based recommendations for the treatment of ADHD in adults, the scientific literature was reviewed, including primary clinical studies, meta-analyses, and available clinical guidelines...

OBJECTIVE: The d-isomer of methylphenidate (d-MPH) is the pharmacologically active part of the racemic mixture of methylphenidate (d,l-MPH), which has been used for decades in the treatment of attention-deficit/hyperactivity disorder (ADHD). A modified release formulation with bimodal release for the pure d-enantiomer (Focalin XR) has been developed to enable a fast onset of action and a sustained activity for once-daily administration. It was intended to achieve a bimodal concentration-time profile as observed after administration of two immediate release Focalin tablets...

Medications for attention deficit hyperactivity disorder (ADHD) currently represent the ninth largest segment of the CNS market by sales, with 2.4 billion USD spent annually on this condition and 40% annual growth. Stimulant medications remain the most effective ADHD therapies and provide robust improvement in ADHD symptoms in both youth and adults. Current prescribing practices favor extended release preparations due to increased convenience, compliance and tolerability with once-daily dosing. Dexmethylphenidate extended release is a long-acting preparation of the ADHD medication Focalin (dexmethylphenidate immediate release) and was approved for marketing by the US Food and Drug administration in June 2005...

RATIONALE: Current medications for attention-deficit/hyperactivity disorder (ADHD) include some single isomer compounds [dextroamphetamine (D: -amphetamine, dexedrine) and dexmethylphenidate (Focalin)] and some racemic compounds [methylphenidate and mixed-salts amphetamine (Adderall)]. Adderall, which contains approximately 25% L: -amphetamine, has been successfully marketed as a first-line medication for ADHD. Although different clinical effects have been observed for D: -amphetamine, Adderall, and benzedrine; potential psychopharmacological differences on the level of neurotransmission between D: -amphetamine and L: -amphetamine have not been well characterized...

OBJECTIVES: d,l-threo-methylphenidate HCl (D,L-MPH) is the most common treatment of attention deficit hyperactivity disorder (ADHD). A previous report showed placebo-controlled efficacy for the purified d-isomer (dexmethylphenidate hydrochloride, d-MPH, Focalin) with a 2:1 potency compared to dl, and suggested a 6-hour duration of action. This study complements that report by studying the effect of placebo-controlled discontinuation and retesting the duration of action. METHODS: A 6-week, open-label titration of d-MPH (2...

OBJECTIVE: To evaluate clinical measures of the benefit/risk ratio in a post hoc analysis of a clinical trial of d-threo-methylphenidate hydrochloride (d-MPH) and d,l-threo-methylphenidate hydrochloride (d,l-MPH). METHOD: Data from a phase III clinical trial was used to compare equimolar doses of d-MPH and d,l-MPH treatment for attention-deficit/hyperactivity disorder (ADHD) on clinician ratings of improvement/deterioration, teacher ratings of remission, and duration of action...
