Background: Patients on the selective serotonergic re-uptake inhibitors (SSRI) like citalopram report emotional blunting. We have shown previously that citalopram reduces resting-state functional connectivity (RSFC) in healthy volunteers in a number of brain regions including the dorso-medial prefrontal cortex, which may be related to its clinical effects. Bupropion is a dopaminergic and noradrenergic re-uptake inhibitor (DNRI) and is not reported to cause emotional blunting. However how bupropion affects RSFC in healthy controls remains unknown...

Across the globe, antidepressants (AD) and phosphodiesterase-5 inhibitors (PDE-5i) are commonly prescribed psychopharmacological agents for patients with co-morbid mental-health problem and sexual dysfunction (SD). The serotonergic and/or noradrenergic ADs, although is an effective agent are not without SD side-effects, especially erectile dysfunction (ED). ED is an inability to achieve, or maintain an erection for satisfactory sexual intercourse during the phases of male's sexual arousal. It is recognized as an important reason why non-adherence to treatment was observed in patients who are on AD...

OBJECTIVE: Because of concerns about potential associations between high doses of citalopram and QTc prolongation in adults, this study examined whether such associations are operant in children. We hypothesized that therapeutic doses of nontricyclic antidepressant medications (non-TCAs) prescribed to children would be cardiovascularly safe. STUDY DESIGN: The sample consisted of 49 psychiatrically referred children and adolescents 6 to 17 years old of both sexes treated with a non-TCA (citalopram, escitalopram, fluoxetine, paroxetine, sertraline, bupropion, duloxetine, venlafaxine, mirtazapine)...

BACKGROUND: Cigarette smoking is one of the most common addictions worldwide. Muslim smokers reduce the number of cigarettes they smoke during Ramadan due to the long fasting hours. OBJECTIVES: We aimed to share our experience in a smoking cessation clinic during Ramadan by analyzing the efficacy and adverse effects of once-daily dosing of bupropion or varenicline in a fasting group compared with conventional dosing in a non-fasting group. METHODS: We analyzed 57 patients who attended our smoking cessation clinic during Ramadan of 2014 and 2015, and at least one follow-up visit...

RATIONALE: We have shown that differences in the level of neural activation to stimuli associated with smoking vs. natural rewards, a biomarker related to reward sensitivity, predict treatment outcome. OBJECTIVES: This paper examined whether this biomarker moderates the impact of bupropion or varenicline on smoking cessation. METHODS: Prior to treatment randomization, smokers (N = 180) in a placebo-controlled trial using bupropion and varenicline completed event-related potential recording (late positive potential, LPP) while viewing pleasant (P), cigarette (C)-related, and other pictures...

Bupropion, an amphetamine-like dual mechanism drug, is approved and increasingly used for the treatment of major depression, and its use is associated with a dose-dependent risk of epileptic seizures. Suicide attempts are frequent in major depression and often an overdose of the drugs available is ingested. Therefore, it is important to be aware of the clinical course, including EEG and neurological symptoms, as well as treatment and prognosis of bupropion intoxication. We report on the clinical and EEG course of a women who ingested 27 g of bupropion in a suicide attempt...

Obesity, an impending global pandemic, is not being effectively controlled by current measures such as lifestyle modifications, bariatric surgery or available medications. Its toll on health and economy compels us to look for more effective measures. Fortunately, the advances in biology and molecular technology have been in our favour for delineating new pathways in the pathophysiology of obesity and have led to subsequent development of new drug targets. Development of anti-obesity drugs has often been riddled with problems in the past...

Bupropion (1), an α-aminophenone uptake inhibitor at plasma membrane transporters for dopamine (DAT) and norepinephrine (NET), is a widely prescribed antidepressant and smoking cessation aid. Cathinone (2), a structurally simpler α-aminophenone, is a substrate-type releasing agent at the same transporters and a recognized drug of abuse. Our goal was to identify the structural features of α-aminophenones that govern the mechanistic transition from uptake inhibition to substrate-induced release. Deconstructed analogs of 1 were synthesized and compared for their ability to interact with DAT, NET, and the serotonin transporter (SERT) using in vitro assay methods...

REVIEW
Faina Gelman, Jessica Atrio
The pathophysiology, diagnosis and treatment of female sexual interest in pre- and post-menopausal women present a complex arena for patients and physicians to navigate. Flibanserin was the first pharmacologic treatment, approved by the United States Food and Drug Administration in August 2015, for hypoactive sexual desire disorder (HSDD) in premenopausal women. Side effects, contraindications and lack of approval in postmenopausal women are all limitations, as are issues surrounding patient and physician knowledge and access...

Fatigue-induced reductions in saccade velocity have been reported following acute, prolonged exercise. Interestingly, the detrimental impact of fatigue on oculomotor control can be prevented by a moderate dose of caffeine. This effect may be related to central catecholamine upregulation via caffeine's action as an adenosine antagonist. To test this hypothesis, we compared the protective effect of caffeine on oculomotor control post-exercise to that of a norepinephrine-dopamine reuptake inhibitor. Within a placebo-controlled crossover design, 12 cyclists consumed placebo, caffeine or a norepinephrine-dopamine reuptake inhibitor (bupropion) during 180 minutes of stationary cycling...

OBJECTIVE: Currently, no valid measures inform treatment selection for depressed patients. Whether C-reactive protein (CRP) in particular and two other acute phase reactants (inflammatory markers) could differentiate between patients responding to either of two treatments with different mechanisms of action was assessed. METHOD: Subjects included Combining Medications to Enhance Depression Outcomes (CO-MED) trial participants randomly assigned to either escitalopram plus placebo (SSRI monotherapy, n=51) or bupropion plus escitalopram combination (bupropion-SSRI combination, n=55) with baseline plasma samples...

BACKGROUND: Within the context of the support program for smoking cessation, initiated by the Turkish Ministry of Health in 2011, those who present at 'smoking cessation' centres and are found to be suitable for pharmacological treatment are given varenicline and bupropion free of charge. As the smoking cessation programme is centralized, the selection of the medication is made randomly to provide a fixed distribution rate. The aim of this study was to evaluate the efficacy of both varenicline and bupropion in smoking cessation and to evaluate the effect of the smoking cessation programme...
