Expert Rev Neurother 2024; 24:743-759. [PMID: 38915262 DOI: 10.1080/14737175.2024.2370346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Accepted: 06/16/2024] [Indexed: 06/26/2024]
Abstract
INTRODUCTION Stimulants, including methylphenidate and amphetamines, are the first-line pharmacological treatment of ADHD in adults. However, in patients who do not respond or poorly tolerate stimulants, non-stimulant medications are usually recommended. AREAS COVERED The authors provide a narrative review of the literature on non-stimulant treatments for adult ADHD, including controlled and observational clinical studies conducted on adult samples. Atomoxetine has been extensively studied and showed significant efficacy in treating adult ADHD. Issues related to dosing, treatment duration, safety, and use in the case of psychiatric comorbidity are summarized. Among other compounds indicated for ADHD in adults, antidepressants sharing at least a noradrenergic or dopaminergic component, including tricyclic compounds, bupropion, and viloxazine, have shown demonstratable efficacy. Evidence is also available for antihypertensives, particularly guanfacine, as well as memantine, metadoxine, and mood stabilizers, while negative findings have emerged for galantamine, antipsychotics, and cannabinoids. EXPERT OPINION While according to clinical guidelines, atomoxetine may serve as the only second-line option in adults with ADHD, several other nonstimulant compounds may be effectively used in order to personalize treatment based on comorbid conditions and ADHD features. Nevertheless, further research is needed to identify and test more personalized treatment strategies for adults with ADHD.

J Psychiatr Res 2024; 176:403-410. [PMID: 38950507 DOI: 10.1016/j.jpsychires.2024.06.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 03/03/2024] [Accepted: 06/26/2024] [Indexed: 07/03/2024]
Abstract
The use of first-line drugs in clinical practice for attention deficit hyperactivity disorder (ADHD) is limited by their adverse effects. Many novel monoamine reuptake inhibitors (MRIs) with better safety profiles and comparable efficacy are also being tried for ADHD. This network meta-analysis (NMA) has evaluated the efficacy and safety of MRIs in ADHD. The data was extracted from 31 relevant clinical trials after a literature search on MEDLINE/PubMed, Embase, Scopus, Cochrane databases, and clinical trial registries. Quality assessment was performed using the risk of bias assessment tool (RoB2) by Cochrane Collaboration, and the random-effects model was used to estimate the effect size. Standardised mean difference (SMD) and 95% credible interval(95%CrI) were reported for the reduction in ADHD rating scale score. Network geometry was visualised, and node splitting was done for the closed triangles. Meta-regression was done for the duration of therapy. PRISMA-NMA guidelines were followed in selecting, analyzing, and reporting findings. The drugs showing significant reduction on the ADHD rating scale as compared to placebo are bupropion (SMD: 0.33; 95%CrI: 0.60,-0.059), dasotraline(SMD: 0.49; 95%CrI: 0.82,-0.16), venlafaxine(SMD: 0.71; 95%CrI: 1.3,-0.15), viloxazine(SMD: 0.45; 95%CrI: 0.77,-0.12). Other drugs (centanafadine, duloxetine, edivoxetine, reboxetine, tipepidine, vortioxetine) were no better than placebo in reducing symptom severity of ADHD. The efficacy of none of the drugs was found to be significantly different as compared to methylphenidate. Among all, duloxetine (OR:15; 95%CrI:1.8130) showed significantly more treatment-emergent adverse events than methylphenidate. In conclusion, venlafaxine, viloxazine, and bupropion are the most efficacious MRIs for ADHD symptom reduction as compared to placebo with high certainty of evidence.

Abstract
INTRODUCTION Adrenergic neurotransmitter reuptake inhibitors are gaining attention in treatment for attention-deficit hyperactivity disorder (ADHD). Due to their effects on norepinephrine, dopamine, and serotonin neurotransmission, they benefit both ADHD and comorbid disorders and have some other advantages including longer duration of action and fewer adverse effects compared to stimulants. There is continued interest in these agents with novel mechanisms of action in treatment of ADHD. AREAS COVERED The authors conducted a PubMed literature search using the following key words: 'ADHD' AND 'adrenergic reuptake inhibitors' OR 'nonstimulants' OR 'atomoxetine' OR 'Viloxazine' OR 'Dasotraline' OR 'Centanafadine' OR 'PDC-1421' OR 'Reboxetine' OR 'Edivoxetine' OR 'Bupropion' OR 'Venlafaxine' OR 'Duloxetine.' They reviewed FDA fact sheets of available medications for safety/tolerability studies and reviewed published clinical studies of these medications for treatment of ADHD. EXPERT OPINION Adrenergic neurotransmitter reuptake inhibitors fit the diverse needs of children and adolescents with ADHD with 1) poor tolerability to stimulants (e.g. due to growth suppression, insomnia, rebound irritability, co-morbid depression, anxiety and tic disorders, substance abuse or diversion concerns), 2) cardiac risks, and/or 3) need for extended duration of action. Their differences in receptor affinities and modulating effects support the unique benefits of individual agents.

Int J Mol Sci 2024; 25:2300. [PMID: 38396978 PMCID: PMC10888658 DOI: 10.3390/ijms25042300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 02/07/2024] [Accepted: 02/08/2024] [Indexed: 02/25/2024] Open
Abstract
The core symptoms of attention deficit hyperactivity disorder (ADHD) are due to the hypofunction of the brain's adrenergic (NE) and dopamine (DA) systems. Drugs that enhance DA and NE neurotransmission in the brain by blocking their transporters or receptors are the current therapeutic strategies. Of late, the emerging results point out the serotonergic (5-HT) system, which indirectly modulates the DA activity in reducing the core symptoms of ADHD. On this basis, second-generation antipsychotics, which utilize 5-HT receptors, were prescribed to children with ADHD. However, it is not clear how serotonergic receptors modulate the DA activity to minimize the symptoms of ADHD. The present study investigates the efficacy of serotonergic and alpha-2 adrenergic receptor manipulation in tackling the core symptoms of ADHD and how it affects the DA neuroreceptors in the brain regions involved in ADHD. Fifteen-day-old male spontaneously hypertensive rats (SHRs) received 5-HT1A agonist (ipsapirone) or 5-HT2A antagonist (MDL 100907) (i.p.) or alpha-2 agonist (GFC) from postnatal days 15 to 42 along with age-matched Wistar Kyoto rats (WKY) (n = 8 in each group). ADHD-like behaviors were assessed using a battery of behavioral tests during postnatal days 44 to 65. After the behavioral tests, rat brains were processed to estimate the density of 5-HT1A, 5-HT2A, DA-D1, and DA-D2 neuroreceptors in the prefrontal cortex, the striatum, and the substantia nigra. All three neuroreceptor manipulations were able to minimize the core symptoms of ADHD in SHRs. The positive effect was mainly associated with the upregulation of 5-HT2A receptors in all three areas investigated, while 5-HT1A was in the prefrontal cortex and the substantia nigra. Further, the DA-D1 receptor expression was downregulated by all three neuroreceptor manipulations except for alpha-2 adrenergic receptor agonists in the striatum and 5-HT2A antagonists in the substantia nigra. The DA-D2 expression was upregulated in the striatum while downregulated in the prefrontal cortex and the substantia nigra. In this animal model study, the 5-HT1A agonist or 5-HT2A antagonist monotherapies were able to curtail the ADHD symptoms by differential expression of DA receptors in different regions of the brain.

Abstract
The neurotransmitter dopamine is a key factor in central nervous system (CNS) function, regulating many processes including reward, movement, and cognition. Dopamine also regulates critical functions in peripheral organs, such as blood pressure, renal activity, and intestinal motility. Beyond these functions, a growing body of evidence indicates that dopamine is an important immunoregulatory factor. Most types of immune cells express dopamine receptors and other dopaminergic proteins, and many immune cells take up, produce, store, and/or release dopamine, suggesting that dopaminergic immunomodulation is important for immune function. Targeting these pathways could be a promising avenue for the treatment of inflammation and disease, but despite increasing research in this area, data on the specific effects of dopamine on many immune cells and disease processes remain inconsistent and poorly understood. Therefore, this review integrates the current knowledge of the role of dopamine in immune cell function and inflammatory signaling across systems. We also discuss the current understanding of dopaminergic regulation of immune signaling in the CNS and peripheral tissues, highlighting the role of dopaminergic immunomodulation in diseases such as Parkinson's disease, several neuropsychiatric conditions, neurologic human immunodeficiency virus, inflammatory bowel disease, rheumatoid arthritis, and others. Careful consideration is given to the influence of experimental design on results, and we note a number of areas in need of further research. Overall, this review integrates our knowledge of dopaminergic immunology at the cellular, tissue, and disease level and prompts the development of therapeutics and strategies targeted toward ameliorating disease through dopaminergic regulation of immunity. SIGNIFICANCE STATEMENT: Canonically, dopamine is recognized as a neurotransmitter involved in the regulation of movement, cognition, and reward. However, dopamine also acts as an immune modulator in the central nervous system and periphery. This review comprehensively assesses the current knowledge of dopaminergic immunomodulation and the role of dopamine in disease pathogenesis at the cellular and tissue level. This will provide broad access to this information across fields, identify areas in need of further investigation, and drive the development of dopaminergic therapeutic strategies.

Abstract
BACKGROUND Receiving treatment for depression is increasingly common among young adults. Antidepressants (AD) are important in depression treatment and modification of medication is common. We examined switches and discontinuations of ADs among young Finnish adults aged 18-29 years. METHODS All persons diagnosed with depression in inpatient or specialized outpatient care or having received sickness absence or disability pension due to depression at age of 18-29 years during 2004-17 were included (N = 110761). Among them, we focused on incident AD users (N = 52855, 47.7%) who were identified with a 6 month washout before AD initiation. The follow-up was 2 years. RESULTS The majority (76.3%) initiated with selective serotonin reuptake inhibitors (SSRIs). The initial AD was switched in 17.4% of cases. Switching was most common when treatment was initiated with tricyclic antidepressants (TCA) or polytherapy, and least common when initiated with SSRIs or serotonin-noradrenaline reuptake inhibitors. Factors associated with switch included initiation with polytherapy, TCA or mirtazapine, and use of benzodiazepines or Z-drugs at baseline. During the first 3 months, 27.6% discontinued AD use, and only 14.1% used AD for 2 years. Factors associated with discontinuation included substance abuse, ADHD, previous suicide attempt and initiation with mirtazapine. SSRIs had the longest time to discontinuation (median 144 days, IQR 64-302). LIMITATIONS Our data sources lack those treated in primary care only, without receiving a sick leave of ≥2 weeks. In addition, we do not have data on severity of depression, social factors or psychotherapy. CONCLUSIONS Special emphasis should be paid to persons with increased risk of discontinuation, including those with previous self-harm/suicide attempt or substance abuse.

Abstract
Attention-deficit hyperactivity disorder (ADHD), has been traditionally considered a neurodevelopmental disorder affecting children and adolescents characterized by inattention, hyperactivity, disruptive behavior, and impulsivity. Although still debated, it is evident that ADHD is also present in adulthood, but this diagnosis is rarely carried out, mainly for the frequent comorbidity with other psychiatric and/or substance abuse disorders. Given the need to shed more light on the pharmacological treatment of ADHD, we performed a naturalistic review to review and comment on the available literature of ADHD treatment across the lifespan. Indeed, stimulants are endowed of a prompt efficacy and safety, whilst non-stimulants, although requiring some weeks to be fully effective, are useful when a substance abuse history is detected. In any case, the pharmacological management of ADHD appears to be still largely influenced by the individual experience of the clinicians. Further longitudinal studies with a careful and detailed characterization of participants across different phases of the lifespan are also required to provide relevant confirmations (or denials) regarding pharmacological treatments amongst the different age groups.

Abstract
INTRODUCTION Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder affecting up to 5.3% of children and 2.5% of adults depending on the country considered. Current pharmacological treatments for ADHD are based on stimulant or non-stimulant medications, targeting dopaminergic and noradrenergic systems in the frontal cortex and dopaminergic system in the basal ganglia. These drugs are effective and safe for the majority of patients, whereas about 20% of treated patients do not tolerate current therapies or experience insufficient efficacy. The adequate treatment of ADHD is necessary to allow a proper social placement and prevent the acquisition of additional, more severe, comorbidities. AREAS COVERED We conducted a review of the scientific literature and of unpublished/ongoing clinical trials to summarize the advances made in the last 10 years (2010-2020) for the pharmacological treatment of ADHD. We found many pharmacological mechanisms beyond dopaminergic and noradrenergic ones have been investigated in patients. EXPERT OPINION Some emerging drugs for ADHD may be promising as add-on treatment especially in children, amantadine to enhance cognitive functions and tipepidine for hyperactivity/impulsivity. Stand-alone emerging treatments for ADHD include viloxazine and dasotraline, which will soon have more clinical data available to support market access requests.

Abstract
BACKGROUND Attention deficit hyperactivity (ADHD) disorder is a neurodevelopmental disorder characterized by inattention, hyperactivity, disruptive behaviour, and impulsivity. Despite considered typical of children for a long time, the persistence of ADHD symptoms in adulthood gained increasing interest during the last decades. Indeed, its diagnosis, albeit controversial, is rarely carried out even because ADHD is often comorbid with several other psychiatric diosrders, in particular with bipolar disorders (BDs), a condition that complicates the clinical picture, assessment and treatment. AIMS The aim of this paper was to systematically review the scientific literature on the neurobiological, clinical features and current pharmacological management of ADHD comorbid with BDs across the entire lifespan, with a major focus on the adulthood. DISCUSSION The pharmacology of ADHD-BD in adults is still empirical and influenced by the individual experience of the clinicians. Stimulants are endowed of a prompt efficacy and safety, whilst non-stimulants are useful when a substance abuse history is detected, although they require some weeks in order to be fully effective. In any case, an in-depth diagnostic and clinical evaluation of the single individual is mandatory. CONCLUSION The comorbidity of ADHD with BD is still a controversial matter, as it is the notion of adult ADHD as a distinct nosological category. Indeed, some findings highlighted the presence of common neurobiological mechanisms and overlapping clinical features, although disagreement does exist. In any case, while expecting to disentangle this crucial question, a correct management of this comorbidity is essential, which requires the co-administration of mood stabilizers. Further controlled clinical studies in large samples of adult ADHD-BD patients appear extremely urgent in order to better define possible therapeutic guidelines, as well as alternative approaches for this potentially invalidating condition.

Abstract
Attention deficit hyperactivity disorder (ADHD) is a prevalent disorder with effective pharmacological treatment that benefits most patients. However, about one-third fail to benefit while others search non-pharmacological alternatives, and for those options are scarce. One alternative treatment option is to alter abnormal right prefrontal cortex (rPFC) activity, given that rPFC abnormality has been repeatedly implicated in ADHD neurophathology. Here, we evaluated whether targeting the rPFC with multiple sessions of repetitive transcranial magnetic stimulation (rTMS), which can modulate neuronal excitability, activity, and plasticity in a non-invasive manner, will affect clinical symptoms in adults suffering from ADHD. Concomitantly, we used EEG to characterize electrophysiological alterations induced by treatment and to search for correlation between baseline neuronal activity and clinical response. Forty-three drug free adults with ADHD were randomized to receive either Real, Active Control, or Sham treatment (13 females, age ranging 21-46; n = 15, 14, 14, respectively), and underwent three weeks of daily high-frequency (18 Hz) stimulation sessions. We found that Real treatment was safe and resulted in significant improvement of symptoms (η2p = 0.34; Cohen's d(against Sham) = 0.96; Cohen's d(against AC) = 0.68; p = 0.00085). Furthermore, based on EEG recorded within the first treatment session we established a novel biomarker, composed of the Alpha and Low-gamma power, which highly correlated the magnitude of the clinical outcome (r = 0.92, p = 0.0001). Taken together, the results of this pilot study indicate safety and effectiveness of rTMS directed to the rPFC for treatment of adult ADHD patients. The biomarker is suggested to reflect the responsiveness of the cortex to this rTMS intervention. Following validation of the results in larger samples, this study may represent a step towards a non-pharmacological treatment for adults with ADHD using EEG-based selection of optimal candidates for treatment.

Mohammadzadeh S, Baghi N, Yousefi F, Yousefzamani B. Effect of omega-3 plus methylphenidate as an alternative therapy to reduce attention deficit-hyperactivity disorder in children. KOREAN JOURNAL OF PEDIATRICS 2019; 62:360-366. [PMID: 31122010 PMCID: PMC6753311 DOI: 10.3345/kjp.2018.06982] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/01/2018] [Accepted: 05/15/2019] [Indexed: 12/16/2022]
Abstract
BACKGROUND Attention deficit-hyperactivity disorder (ADHD) is one of the most common chronic behavioral disorders in school-aged children. PURPOSE This study aimed to evaluate the effect of omega-3 supplementation as an alternative therapy for ADHD, which can be caused by vitamin and mineral deficiencies. METHODS This was a double-blinded clinical trial study. Sixty-six children with ADHD (aged 6-12 years) referred to our child and adolescent psychiatric educational and therapeutic clinic were selected based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. Instruments including the Parent ADHD Rating Scale were used to assess ADHD at 0, 2, 4, and 8 weeks during the study. RESULTS The results showed no statistically significant difference between the methylphenidate with omega-3 group and methylphenidate with placebo group based on the Parents ADHD Rating Scale between week 0 (P≥0.96) and week 8 (P≥0.75). There were no significant intergroup differences between the Inattention (P≥0.48) and hyperactivity/impulsivity (P≥0.80) subscale scores on the Parents ADHD Rating Scale. The most common drug complications in the methylphenidate with placebo and methylphenidate with omega-3 groups were anorexia (27 [54%] vs. 41 [60.29%], respectively) and diarrhea (10 [20%] vs. 8 [11.76%], respectively), but the differences were not statistically significant (P> 0.05). CONCLUSION Our results demonstrate that a specific dose of omega-3 for 8 weeks had no effect on ADHD.

Abstract
OBJECTIVE The aim of the study was to analyze evidence comparing the profile of drugs used to treat ADHD in adult patients. METHOD Systematic searches were conducted in electronic databases. Randomized, double-blind, parallel controlled trials that evaluated the safety of drugs in ADHD were included. The statistical analyses were conducted by pairwise meta-analyses and mixed treatment comparison (MTC). RESULTS Ten ( n = 3006) trials were included in the analyses. We observed statistical differences for the following outcomes: decreased appetite between atomoxetine and placebo (odds ratio [OR] = 0.15, 95% credibility interval [CrI] = [0.05, 0.38]) and extended-release mixed amphetamine salts and placebo (OR = 0.06, 95% CrI = [0.00, 0.51]); insomnia between atomoxetine and placebo (OR = 0.48, 95% CrI = [0.27, 0.88]) and extended-release mixed amphetamine salts and placebo (OR = 0.23, 95% CrI = [0.06, 0.76]); sleepiness between atomoxetine and methylphenidate OROS (OR = 0.24, 95% CrI = [0.06, 0.97]); and decreased libido between atomoxetine and placebo (OR = 0.28, 95% CrI = [0.08, 0.90]). CONCLUSION It was possible to generate evidence about the safety profile of different ADHD drugs.

Abstract
BACKGROUND Hyperactivity disorder and attention deficit are common neurological disorders in children and adolescents. The symptoms of hyperactivity are decreased in adults, and attention deficit is more noticeable. This study was carried out to evaluate the effect of memantine on adult patients with attention deficit hyperactivity disorder (ADHD). MATERIALS AND METHODS In a double-blind clinical trial study, 40 patients aged 18 to 45 years with ADHD were selected on the basis on the Diagnosis and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria, and randomly assigned memantine or placebo. Before starting the treatment, Conners' screening questionnaire was completed for each patient, and the subjects were entered the study after acquiring minimum acceptable score in the questionnaire. RESULTS The mean age of patients who were receiving memantine and placebo was about 34.7 ± 4.48 and 31.5 ± 7.4 years, respectively. The results have shown a significant difference in the behavior and attention deficit between the two groups treated with memantine and placebo during 6 weeks (p < 0.001). Also, there was a significant difference in the third and sixth weeks between treatment groups in hyperactivity and attention deficit index (p = 0.001). CONCLUSION The results of this study indicated that memantine was effective in reducing symptoms of Inattention/Memory Problems, Hyperactivity/Restlessness, Impulsivity/Emotional Lability.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is often comorbid with anxiety disorders such as generalized anxiety disorder, but the best approach to treat this comorbidity in adults has yet to be determined, as current evidence on which disorder should be treated first is poor and conflicting. In this report, we present 1 case in which we treated adult ADHD first and 1 case in which we treated generalized anxiety disorder before prescribing any medication for ADHD. More studies are required on this topic, but our results suggest that treating anxiety disorders until a clear reduction of anxiety symptoms is observed, or at least taking a combined treatment approach, is more appropriate than treating adult ADHD alone and waiting for a reduction in anxiety symptoms as a secondary effect.

Abstract
BACKGROUND The role of nutrition in the treatment of attention-deficit hyperactivity disorder (ADHD) is gaining international attention; however, treatments have generally focused only on diet restriction or supplementing with one nutrient at a time. AIMS To investigate the efficacy and safety of a broad-based micronutrient formula consisting mainly of vitamins and minerals, without omega fatty acids, in the treatment of ADHD in adults. METHOD This double-blind randomised controlled trial assigned 80 adults with ADHD in a 1:1 ratio to either micronutrients (n = 42) or placebo (n = 38) for 8 weeks (trial registered with the Australian New Zealand Clinical Trials Registry: ACTRN12609000308291). RESULTS Intent-to-treat analyses showed significant between-group differences favouring active treatment on self- and observer- but not clinician-ADHD rating scales. However, clinicians rated those receiving micronutrients as more improved than those on placebo both globally and on ADHD symptoms. Post hoc analyses showed that for those with moderate/severe depression at baseline, there was a greater change in mood favouring active treatment over placebo. There were no group differences in adverse events. CONCLUSIONS This study provides preliminary evidence of efficacy for micronutrients in the treatment of ADHD symptoms in adults, with a reassuring safety profile.

Abstract
BACKGROUND Some trials have suggested that bupropion, as well as methylphenidate, is beneficial in the treatment of attention-deficit/hyperactivity disorder (ADHD). OBJECTIVES The purpose of this systematic review was to summarize the efficacy, acceptability, and tolerability of bupropion in comparison with methylphenidate for ADHD treatment. Included studies were randomized controlled trials (RCTs) that compared bupropion and methylphenidate. Clinical studies conducted between January 1991 and January 2014 were reviewed. DATA SOURCES MEDLINE(®), EMBASE™, CINAHL, PsycINFO(®), and the Cochrane Controlled Trials Register were searched in January 2014. Additionally, clinical trials were identified from the databases of ClinicalTrials.gov and the EU Clinical Trials Register. STUDY ELIGIBLE CRITERIA PARTICIPANTS AND INTERVENTIONS All RCTs of bupropion and methylphenidate reporting final outcomes relevant to 1) ADHD severity, 2) response or remission rates, 3) overall discontinuation rate, or 4) discontinuation rate due to adverse events. Language restriction was not applied. STUDY APPRAISAL AND SYNTHESIS METHODS The relevant clinical trials were examined and the data of interest were extracted. Additionally, the risks of bias were also inspected. The efficacy outcomes were the mean changed scores of ADHD rating scales, the overall response rate, and the overall remission rates. The overall discontinuation rate and the discontinuation rate due to adverse events were determined. Relative risks and weighted mean differences or standardized mean differences with 95% confidence intervals were estimated using a random effect model. RESULTS A total of 146 subjects in four RCTs comparing bupropion with methylphenidate in the treatment of ADHD were included. The pooled mean changed scores of the Iowa-Conner's Abbreviated Parent and Teacher Questionnaires and the ADHD Rating Scale-IV for parents and teachers of children and adolescents with ADHD in the bupropion- and methylphenidate-treated groups were not significantly different. Additionally, the pooled mean changed score in adult ADHD between the two groups, measured by the ADHD Rating Scale-IV and the Adult ADHD Rating Scale, was also not significantly different. The pooled rates of response, overall discontinuation, and discontinuation due to adverse events between the two groups were not significantly different. CONCLUSION Based on limited data from this systematic review, bupropion was as effective as methylphenidate for ADHD patients. Additionally, tolerability and acceptability were also comparable. However, these findings should be considered as very preliminary results. To confirm this evidence, further studies in this area should be conducted.

Abstract
PURPOSE OF REVIEW This article reviews recent advances in the pharmacological treatment of adult attention deficit hyperactivity disorder (ADHD), focusing on the literature of the last 18 months. RECENT FINDINGS Recent works highlight the growing number of treatment options and focus on the effects of pharmacological treatment in special areas of adult ADHD including emotional dysregulation, social functioning or driving performance. Significant clinical improvement was demonstrated in special subgroups, for example, in substance dependent or prison populations with adult ADHD. In our earlier meta-analysis, we estimated the effect size for the pharmacotherapy of adult ADHD in short-term placebo-controlled studies to be in the medium-to-high range (Cohen-d = 0.65). We now replicate these results with the help of most recent studies: stimulants had greater efficacy than nonstimulants. SUMMARY Recent studies are consistent with prior reports and indicated that pharmacological treatment of adult ADHD is effective in improving symptoms and other domains, such as social dysfunction, functional impairment and executive functions. Furthermore, we calculated effect sizes from the most recent studies and they are almost identical with prior estimates, and in terms of Cohen-d typically indicate medium-to-high effect sizes for the pharmacotherapy of adult ADHD.
