[Pharmacotherapy of attention deficit hyperactivity disorder in adults].
r M Abstract Pharmacotherapy is a central component in the context of an overall therapeutic concept in the treatment of adults with attention deficit hyperactivity disorder (ADHD). In this concept psychosocial interventions with psychoeducation or specific psychotherapy measures also play an important role. In adults three compounds are currently approved for the pharmacological treatment of ADHD in Germany. The long-acting stimulants retarded methylphenidate preparations and lisdexamfetamine can be prescribed. Alternatively, the adrenergic uptake inhibitor atomoxetine can be used. In several meta-analyses g...

Spontaneous Ejaculation Induced with Atomoxetine.
Authors: Yaylacı F, Şahbudak B, Küçük Ö Abstract Attention Deficit-Hyperactivity Disorder is one of the most common psychiatric disorders of childhood, characterized by attention deficit, hyperactivity and impulsivity. The most effective treatment in ADHD is drug treatment. Stimulant and nonstimulant drug treatments are preferentially used. Atomoxetine is one of the nonstimulant treatments. Although sexual side effects of atomoxetine in adults are reported, there is limited knowledge about sexual side effects in children and adolescents. In this case report, we aimed to describe an adolescen...

Effects of 5-HT2C receptor modulation and the NA reuptake inhibitor atomoxetine in tests of compulsive and impulsive behaviour.
Abstract Drug repositioning has gained strategic value as a reaction to high attrition rates of new drugs as they pass through the clinical development process. The 5-HT2C receptor agonist lorcaserin (Belviq®), and the selective NA reuptake inhibitor atomoxetine (Strattera®) represent two drugs FDA approved for obesity and ADHD respectively. Although both drugs are of differing pharmacological class, each share a property of regulating impulsive behaviours in preclinical studies, and thus represent candidates for consideration in clinical conditions labelled as 'impulsive-compulsive disorders'. The present...

Simple pharmacokinetic models accounting for drug monitoring results of atomoxetine and its 4-hydroxylated metabolites in Japanese pediatric patients genotyped for cytochrome P450 2D6.
Authors: Notsu Y, Shimizu M, Sasaki T, Nakano A, Ota M, Yoshida S, Yamazaki H Abstract Atomoxetine is an approved medicine for attention-deficit/hyperactivity disorder and a cytochrome P450 2D6 (CYP2D6) probe substrate. Simple physiologically based pharmacokinetic (PBPK) models and compartment models were set up to account for drug monitoring results of 33 Japanese patients (6-15 years of age) to help establish the correct dosage for the evaluation of clinical outcomes. The steady-state one-point drug monitoring data for the most participants indicated the extensive biotransformation of atomoxetine to 4-hydroxyatom...

A Severe Adverse Effect of Atomoxetine: Hypertensive Crisis
Atomoxetine, a selective norepinephrine (noradrenaline) reuptake inhibitor, is an effective medication in attention-deficit hyperactivity disorder with a generally well-tolerated adverse effect profile. However, unusual side effects may occur during treatment. Here we report a case of hypertensive crisis in an 8-year-old male patient with autism spectrum disorder and attention-deficit hyperactivity disorder receiving atomoxetine treatment. We plan to discuss the clinical picture of the subject and importance of close monitoring during atomoxetine treatment. (Source: Clinical Neuropharmacology)

Effects of the Combination of Atomoxetine and Oxybutynin on Obstructive Sleep Apnea Endotypic Traits.
Abstract BACKGROUND: We recently showed that the administration of the combination of the noradrenergic drug atomoxetine plus the antimuscarinic oxybutynin (ato-oxy) before sleep greatly reduced obstructive sleep apnea (OSA) severity, likely by increasing upper airway dilator muscle activity during sleep. RESEARCH QUESTION: In patients with OSA who performed the ato-oxy trial with an esophageal pressure catheter to estimate ventilatory drive, we measured the effect of the drug combination (n=17) and of the single drugs (n=6) on the endotypic traits (listed below) over a 1-night administration and compared it ...

Drugs for ADHD
Date: January 27, 2020 Issue #: 1590Summary: Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurodevelopmental disorder that has been diagnosed in up to 10% of school-age children in the US and frequently persists into adulthood. A study in a large Danish cohort found that ADHD was associated with higher mortality rates in children, adolescents, and adults, mainly due to accidents. Pharmacologic treatment of ADHD in children has been reported to decrease the risk of substance abuse in adolescents, and use of ADHD medications in adults has been associated with a reduced risk of s...

ADHD symptoms were measured using behavioral tests, open field for hyperactivity and the Y-maze for spatial working memory. Further, ATX effects on long-term potentiation (LTP) in hippocampal slices at the CA3–CA1 synapse were assessed. PNE mice exhibited the behavioral deficits of ADHD, hyperactivity and spatial memory impairment. Intraperitoneal injection of ATX (2 mg/kg/day) normalized these behaviors significantly after 7 days.

We examined the effects of the high affinity NET inhibitors atomoxetine or nisoxetine and the low affinity DAT inhibitor bupropion, either alone or in combination, on short- and long-term memory of Pavlovian fear conditioning. We also examined the addiction-related effects of combined strong NET and weak DAT inhibition using conditioned place preference and a locomotor activity test. While atomoxetine or nisoxetine alone enhanced short-term fear memory, the addition of bupropion was required to significantly enhance long-term fear memory.

Atomoxetine modulates the relationship between perceptual abilities and response bias
AbstractElucidation of how neuromodulators influence motivated behaviors is a major challenge of neuroscience research. It has been proposed that the locus-c œruleus-norepinephrine system promotes behavioral flexibility and provides resources required to face challenges in a wide range of cognitive processes. Both theoretical models and computational models suggest that the locus-cœruleus-norepinephrine system tunes neural gain in brain circuits to opt imize behavior. However, to the best of our knowledge, empirical proof demonstrating the role of norepinephrine in performance optimization is scarce. Here, we m...

The use of reaction time distributions to study attention in male rats: the effects of atomoxetine and guanfacine
ConclusionsIT devmode is a measure of distribution skew thought to reflect lapses of attention. The effects of ATX on IT devmode suggest that increased synaptic NE reduces attentional lapses. These findings are consistent with human reports of reduced RTV after ATX administration. The same pattern of results with guanfacine suggests that the effects of increased NE are due in part to binding at α-2 noradrene rgic receptors. (Source: Psychopharmacology)

Abstract Pharmacogenetics is a key component of precision medicine. Genetic variation in drug metabolism enzymes can lead to variable exposure to drugs and metabolites, potentially leading to inefficacy and drug toxicity. Although the evidence for pharmacogenetic associations in children is not as extensive as for adults, there are several drugs across diverse therapeutic areas with robust pediatric data indicating important, and relatively common, drug-gene interactions. Guidelines to assist gene-based dose optimization are available for codeine, thiopurine drugs, selective serotonin reuptake inhibitors, atomoxet...
