Results regarding the effects of methylphenidate and atomoxetine on executive functions were inconsistent and no study has directly compared the efficacy of these two medications in improving executive functions in adults with attention-deficit hyperactivity disorder (ADHD). We conducted an 8-10 wk, open-label, head-to-head, randomized clinical trial involving adults with a clinical diagnosis o...

OBJECTIVE To compare the short term efficacy and tolerability of methylphenidate and atomoxetine in children with Attention deficit hyperactivity disorder (ADHD). DESIGN Open label randomized parallel group clinical trial. SETTING Child Guidance Clinic of a tertiary care hospital of Northern India from October 2010 to June 2012. PARTICIPANTS 69 patients (age 6-14 y) with a diagnosis of AD...

Atomoxetine, a selective norepinephrine transporter blocker, could increase blood pressure by elevating norepinephrine concentration in peripheral sympathetic neurons. This effect may be masked in healthy subjects by central sympatholytic mechanisms. To test this hypothesis we studied the pressor effect of 18 mg of atomoxetine (pediatric dose) in 21 patients with damage of the central (10 subje...

OBJECTIVE Methylphenidate has prominent effects in the dopamine-rich striatum that are absent for the selective norepinephrine transporter inhibitor atomoxetine. This study tested whether baseline striatal activation would predict differential response to the two medications in youth with attention-deficit/hyperactivity disorder (ADHD). METHOD A total of 36 youth with ADHD performed a Go/No-G...

A RP-HPLC method was developed for the estimation of Atomoxetine Hydrochloride in tablet formulation, which is novel to the market. Chromatographic separation of the drug was achieved on a ENABLE C-18 G, 5μm, column (250 × 4.6 mm) using a mobile phase, Methanol: Ammonium phosphate buffer pH-3 (80:20 V/V) at a flow rate of 1ml/min. The drug eluted was monitored at 227 nm. The retention time was ...

BACKGROUND Many effective treatments for nicotine addiction inhibit noradrenaline reuptake. Three recent studies have suggested that another noradrenaline reuptake inhibitor, atomoxetine, may reduce smoking behaviors. METHODS The present double-blind, placebo-controlled, fixed-dose study was carried out over 21 days during which administration of 40 mg atomoxetine was compared to placebo in 1...

Methylphenidate induces reanimation (active emergence) from general anesthesia in rodents, and recent evidence suggests that dopaminergic neurotransmission is important in producing this effect. Dextroamphetamine causes the direct release of dopamine and norepinephrine, whereas atomoxetine is a selective reuptake inhibitor for norepinephrine. Like methylphenidate, both drugs are prescribed to t...

Atomoxetine is a novel, non-stimulant, highly selective noradrenaline reuptake inhibitor that has been studied for use in the treatment of attention deficit/hyperactivity disorder (ADHD). Data from clinical trials show it to be well tolerated and effective in the treatment of ADHD in children, adolescents, and adults. Improvements were seen not only in core symptoms of ADHD, but also in broader...

spectrophotometric and electrochemical studies were successfully used in quantitative analysis of amitriptyline hydrochloride (ath) and nortriptyline hydrochloride (nth). conductometric titration were carried out in equeous solution using iodide and dopamine and serotonine as titrant. two new methods using spectrophotometry are dascribed for the determination of (ath) and (nth) with potassium b...
