Pharmacokinetics of lisdexamfetamine dimesylate and its active metabolite, d-amphetamine, with increasing oral doses of lisdexamfetamine dimesylate in children with attention-deficit/hyperactivity disorder: a single-dose, randomized, open-label, crossover study.

Background: Lisdexamfetamine dimesylate (LDX) is a long-acting oral prodrug stimulant indicated for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children 6 to 12 years old and in adults. Information on the pharmacokinetic profile of LDX in children with ADHD is lacking.

Objective: The aim of this study was to assess the pharmacokinetic properties of d-amphetamine delivery from LDX, and intact LDX with increasing doses of LDX administered in children with ADHD.

Long-term tolerability of the methylphenidate transdermal system in pediatric attention-deficit/hyperactivity disorder: a multicenter, prospective, 12-month, open-label, uncontrolled, phase III extension of four clinical trials.

Background: Short-term treatment with the meth-ylphenidate transdermal system (MTS) has been well tolerated in several clinical trials in children with attention-deficit/hyperactivity disorder (ADHD). However, the effects of long-term use have not been systematically evaluated.

Objectives: The primary objective of this study was to assess the 12-month tolerability of MTS in children with ADHD.

Varying the wear time of the methylphenidate transdermal system in children with attention-deficit/hyperactivity disorder.

Objective: Children with attention-deficit/hyperactivity disorder often have varying needs for coverage of their symptoms throughout the day. The objectives of this study were to determine the efficacy, duration of action, and safety of methylphenidate transdermal system worn for variable times by children (ages 6-12) diagnosed with ADHD.

Method: Methylphenidate dose was optimized over 5 weeks using 10-, 15-, 20-, or 30-mg patches worn for 9 hours.

Pharmacokinetics of a guanfacine extended-release formulation in children and adolescents with attention-deficit-hyperactivity disorder.

Study Objective: To evaluate the single- and multiple-dose pharmacokinetics of an oral extended-release formulation of guanfacine in children and adolescents with a diagnosis of attention-deficit-hyperactivity disorder (ADHD).

Design: Phase I-II, open-label, dose-escalation study.

Setting: Clinical study center.

Lisdexamfetamine dimesylate and mixed amphetamine salts extended-release in children with ADHD: a double-blind, placebo-controlled, crossover analog classroom study.

Background: Lisdexamfetamine dimesylate is a therapeutically inactive prodrug in which d-amphetamine is covalently bound to l-lysine, a naturally occurring amino acid. Pharmacologically active d-amphetamine is released from lisdexamfetamine following oral ingestion.

Methods: This phase 2, randomized, double-blind, placebo- and active-controlled crossover study compared the efficacy and safety of lisdexamfetamine (LDX: 30, 50, or 70 mg) with placebo, with mixed amphetamine salts extended-release (MAS XR: 10, 20, or 30 mg) included as a reference arm of the study, in 52 children aged 6 to 12 years with attention-deficit/hyperactivity disorder (ADHD) in an analog classroom setting.

Modafinil in children and adolescents with attention-deficit/hyperactivity disorder: a preliminary 8-week, open-label study.

Objective: In a 4-week, double-blind, placebo-controlled study, the attention-promoting agent modafinil improved symptoms of attention-deficit/hyperactivity disorder (ADHD) in children and adolescents and was well tolerated. To assess the continued efficacy of modafinil and obtain additional safety data, an 8-week, open-label study was conducted as an extension to the double-blind study.

Method: Two hundred and twenty children and young adolescents (age range, 6-14 years) with ADHD who had completed 4 weeks of the double-blind period or had withdrawn for reasons other than an adverse event were enrolled.

A comparison of once-daily and divided doses of modafinil in children with attention-deficit/hyperactivity disorder: a randomized, double-blind, and placebo-controlled study.

Objective: This randomized, double-blind, placebo-controlled study assessed the efficacy and tolerability of several modafinil dosing regimens in children with attention-deficit/hyperactivity disorder (ADHD) to determine whether modafinil can be given once daily in pediatric ADHD.

Method: Children and adolescents (age range, 6-13 years) (N = 248) with DSM-IV-defined ADHD were enrolled in a 4-week, double-blind, placebo-controlled study, conducted February-May 2002. The group was assigned to receive oral (100-mg tablets) modafinil 300 mg once daily (300 mg in the morning followed by placebo at midday), modafinil 300 mg as a divided dose (100/200 mg or 200/100 mg), or matching placebo.

A randomized, double-blind, placebo-controlled study of modafinil film-coated tablets in children and adolescents with attention-deficit/hyperactivity disorder.

Objective: To evaluate the efficacy and tolerability of modafinil in children and adolescents, ages 7 to 17, with attention-deficit/hyperactivity disorder (ADHD).

Method: In this 9-week, double-blind, flexible-dose study, patients were randomized to once-daily modafinil (170-425 mg) or placebo. Assessments included ADHD Rating Scale-IV (ADHD-RS-IV) School and Home Versions and Clinical Global Impression of Improvement (CGI-I) scale.

Efficacy and safety of modafinil film-coated tablets in children and adolescents with attention-deficit/hyperactivity disorder: results of a randomized, double-blind, placebo-controlled, flexible-dose study.

Objective: Modafinil, which is structurally and pharmacologically different from other agents that are used for the treatment of children with attention-deficit/hyperactivity disorder (ADHD), selectively activates the cortex and has low potential for abuse. Initial studies of the use of modafinil to treat ADHD showed significant improvements in the core symptoms of the disorder, namely inattention, hyperactivity, and impulsivity. This study evaluated a new formulation of modafinil (modafinil film-coated tablets) in children and adolescents with ADHD.

A randomized, double-blind, placebo-controlled, parallel-group study of SLI381 (Adderall XR) in children with attention-deficit/hyperactivity disorder.

Objective: SLI381 (Adderall XR) is a 2-component extended-release capsule formulation of Adderall designed to produce a therapeutic effect that lasts throughout the day with 1 morning dose. The primary objective of this study was to assess the efficacy and safety of SLI381 compared with placebo in the treatment of attention-deficit/hyperactivity disorder (ADHD) in children in a naturalistic school and home setting. A secondary objective was to assess the diurnal variation in responses based on morning and afternoon assessments.
