Objective: The aim of this study was to compare fluoxetine dosage titration to 40-60 mg/day with fixed fluoxetine 20-mg/day treatment for an additional 10 weeks in pediatric outpatients with major depressive disorder (MDD) who had not met protocol-defined response criteria after 9-week acute fluoxetine treatment.
Methods: Patients unresponsive (less than or equal to 30% decrease in Children's Depression Rating Scale-Revised [CDRS-R] score) after 9-week fluoxetine treatment were randomly reassigned to continue at 20 mg/day or to increase to 40 mg/day. After 4 weeks, patients unresponsive to 40 mg/day could receive 60 mg/day.

Objective: The aim of this study was to assess the safety of subchronic fluoxetine treatment for major depressive disorder (MDD) in children and adolescents.
Methods: Patients received up to 19 weeks of treatment with fluoxetine, 10 mg-60 mg daily. Safety was evaluated through the reporting of concomitant medications, vital signs, routine laboratory testing, electrocardiograms (ECGs), and adverse event data.
Objective: To compare fluoxetine 20 to 60 mg/day with placebo for prevention of relapse of major depressive disorder in children and adolescents who had achieved Children's Depression Rating Scale, Revised scores of < or =28 during treatment with fluoxetine 20 to 60 mg.
Method: In this 32-week relapse-prevention phase of a double-blind, multicenter, placebo-controlled 51-week study, 20 patients continued to receive their fixed dose of fluoxetine (F/F group), while 20 similar patients were switched to placebo (F/P group). Definition of relapse for the primary analysis was a Children's Depression Rating Scale, Revised score of >40 with a 2-week history of clinical deterioration or relapse in the opinion of the physician.
Pediatric psychopharmacology research is undergoing a major expansion consequent to increasing use of psychotropic medications in children and recent legislative incentives to industry. In this rapidly changing context, the interface between publicly and privately funded research needs to be reconsidered to integrate activities and avoid unnecessary duplication of efforts. Once, by default, the almost exclusive domain of public research, child research is now increasingly funded by industry.

Atomoxetine is a highly specific inhibitor of the presynaptic norepinephrine transporter with minimal affinity for other noradrenergic receptors or other neurotransmitter transporters or receptors. Results of 2 proof-of-concept studies are reported that tested the hypothesis that a selective inhibitor of presynaptic norepinephrine uptake would be effective for the treatment of ADHD in school-aged children.

Atomoxetine is a potent inhibitor of the presynaptic norepinephrine transporter with minimal affinity for other noradrenergic receptors or for other neurotransmitter transporters or receptors.
Methods: A total of 291 children who were 7 to 13 years of age and met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for ADHD participated in 1 of 2 combined, double-blind, placebo-controlled, multisite, identical clinical trials.

The selective norepinephrine (NE) transporter inhibitor atomoxetine (formerly called tomoxetine or LY139603) has been shown to alleviate symptoms in Attention Deficit/Hyperactivity Disorder (ADHD). We investigated the mechanism of action of atomoxetine in ADHD by evaluating the interaction of atomoxetine with monoamine transporters, the effects on extracellular levels of monoamines, and the expression of the neuronal activity marker Fos in brain regions. Atomoxetine inhibited binding of radioligands to clonal cell lines transfected with human NE, serotonin (5-HT) and dopamine (DA) transporters with dissociation constants (K(i)) values of 5, 77 and 1451 nM, respectively, demonstrating selectivity for NE transporters.

Background: This report presents results from the acute treatment phase of a clinical trial designed to confirm efficacy of a fixed dose of 20 mg of fluoxetine in children and adolescents with major depressive disorder (MDD).
Method: After a 3-week screening period, 122 children and 97 adolescents with MDD ( ) were randomly assigned to placebo or fluoxetine. After a 1-week placebo lead-in, fluoxetine-treated patients received fluoxetine 10 mg/day for 1 week, then fluoxetine 20 mg/day for 8 weeks.
Objective: To assess the comparability of atomoxetine, a new therapy for attention-deficit/hyperactivity disorder (ADHD) and methylphenidate. (Atomoxetine was originally called tomoxetine. The name was recently changed in order to avoid any potential confusion with tamoxifen that might lead to errors in dispensing drug.
