OBJECTIVE: Bupropion is often categorized as a newer generation antidepressant and assessed with serotonin reuptake inhibitors as a lower risk than older tricyclic antidepressants (TCAs). The objective of this study was to compare outcomes in adolescent suicide from ingestions between bupropion and TCA medications. STUDY DESIGN: An analysis of the National Poison Data System for exposures coded "suspected suicide" in adolescents (age: 13-19) was undertaken for the years 2013-2016 and included TCAs or bupropion...

Tobacco smoking contributes to about six million deaths per year and is predicted to increase in the future. Several pharmacological interventions are used for smoking cessation. Trials using nicotine replacement therapy (NRT) in acute coronary syndrome (ACS) showed inconclusive results. Furthermore, three trials using bupropion in patients admitted with ACS failed to show improvement in smoking cessation compared with placebo. Interestingly, only one trial using varenicline was successful in achieving smoking abstinence in the acute setting...

Computational drug repositioning methods can scalably nominate approved drugs for new diseases, with reduced risk of unforeseen side effects. The majority of methods eschew individual-level phenotypes despite the promise of biomarker-driven repositioning. In this study, we propose a framework for discovering serendipitous interactions between drugs and routine clinical phenotypes in cross-sectional observational studies. Key to our strategy is the use of a healthy and non-diabetic population derived from the National Health and Nutrition Examination Survey, mitigating risk for confounding by indication...

Conventional treatment for obesity with diet, exercise and bariatric surgery has limitations; thus, it is necessary to have pharmacological tools. In the past, different drugs were marketed that were withdrawn due to safety problems. There are currently 3 drugs approved by the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) for obesity therapy (orlistat, combination of bupropion and delayed-release naltrexone and liraglutide) and two more only authorized by FDA (lorcaserin and the combination of phentermine and extended release topiramate)...

Mohammed Shoaib, Yazead Buhidma
Before the advent of varenicline, antidepressant drugs were reported to exhibit better clinical efficacy than nicotine replacement therapy as smoking cessation aids. The most studied is bupropion, a clinically-effective antidepressant, the first to be marketed throughout Europe for smoking cessation. The mechanisms behind bupropion's efficacy as a smoking cessation compound remains unclear. Since depression and tobacco smoking have a high incidence of co-occurrence, this would implicate an underlying link between these two conditions...

OBJECTIVE: To understand the dynamic relations among tobacco withdrawal symptoms to inform the development of effective smoking cessation treatments. Dynamical system models from control engineering are introduced and utilized to evaluate complex treatment effects. We demonstrate how dynamical models can be used to examine how distinct withdrawal-related processes are related over time and how treatment influences these relations. METHOD: Intensive longitudinal data from a randomized placebo-controlled smoking cessation trial (N=1504) are used to estimate a dynamical model of withdrawal-related processes including momentary craving, negative affect, quitting self-efficacy, and cessation fatigue for each of six treatment conditions (nicotine patch, nicotine lozenge, bupropion, patch + lozenge, bupropion + lozenge, and placebo)...

RATIONALE: Racemic (RS)-amisulpride (Solian(®)) is an atypical antipsychotic drug used to treat schizophrenia and dysthymia. Blockade of dopamine D2/D3 and/or serotonin 5-HT7 receptors is implicated in its pharmacological effects. While the (S)-amisulpride isomer possesses a robust discriminative cue, discriminative stimulus properties of (RS)-amisulpride have not been evaluated. OBJECTIVES: The present study established (RS)-amisulpride as a discriminative stimulus and assessed amisulpride-like effects of amisulpride stereoisomers, other benzamide derivatives, and antipsychotic, antidepressant, and anxiolytic drugs...

INTRODUCTION: Alcohol, tobacco, and illegal drug usage is pervasive throughout the world, and abuse of these substances is a major contributor to the global disease burden. Many pharmacotherapies have been developed over the last 50years to target addictive disorders. While the efficacy of these pharmacotherapies is largely recognized, their cognitive impact is less known. However, all substance abuse disorders are known to promote cognitive disorders like executive dysfunction and memory impairment...

INTRODUCTION: Binge eating disorder (BED) is associated with obesity and major depressive disorder (MDD). Naltrexone extended-release (ER)/bupropion ER (NB) is approved as an adjunct to diet and physical activity for chronic weight management. In a prospectively designed 24-week open-label, single-arm, single-site trial of 25 women with MDD and overweight/obesity, NB reduced weight and depressive symptoms. METHODS: This post hoc analysis investigated the relationship between change in self-reported binge eating behavior (evaluated with the Binge Eating Scale [BES]) and changes in weight, control of eating, and depressive symptoms...

Approximately 30-60% of patients treated with existing antidepressants fail to achieve remission of depressive symptoms leading to Treatment Resistant Depression (TRD). There is an urgent need to develop novel medications, which is highly limited by the non-availability of relevant animal models with good predictive validity. ACTH administration has been shown to result in the resistance to acute and chronic effects of imipramine. However, the pharmacology of the model and the mechanisms contributing to the resistance are not completely understood...

BACKGROUND: Tobacco smoking is the leading preventable cause of death worldwide, which makes it essential to stimulate smoking cessation. The financial cost of smoking cessation treatment can act as a barrier to those seeking support. We hypothesised that provision of financial assistance for people trying to quit smoking, or reimbursement of their care providers, could lead to an increased rate of successful quit attempts. This is an update of the original 2005 review. OBJECTIVES: The primary objective of this review was to assess the impact of reducing the costs for tobacco smokers or healthcare providers for using or providing smoking cessation treatment through healthcare financing interventions on abstinence from smoking...

Identifying compulsive consumption of marijuana in association with another mental disorder (attentional defcit disorder, bipolar disorder, depression or psychosis) presents the challenge of clarifying validated therapeutic strategies, especially within the teen population, in which it shows the highest prevalence. The ever-increasing prevalence and the need for regional treatments, demand that we approach this health matter as a public health issue. The ideological con?icts related to the necessary decriminalization of consumption and the current debate on the medical use of marijuana often confuse the urgent need to establish effective therapeutic strategies for the population affected by this mental disorder...

The forced swim test (FST) is a commonly used preclinical animal behavioural model for prediction of antidepressant activity in humans. While the FST may qualitatively predict efficacy, less is known about the quantitative translation of FST data to human efficacious doses. Assessing quantitative translation allows better predictions of human efficacious doses and a higher chance of success in the drug development process. Dose-response and time-course FST experiments were carried out on mice using four marketed antidepressants (citalopram, desipramine, bupropion, desvenlafaxine) in addition to ketamine, all with varying mechanisms of action...

3,4-Methylenedioxypyrovalerone (MDPV) is a common constituent of illicit bath salts products, and in vitro studies implicate monoamine transporters as mediators of its pharmacological effects. Locomotor and thermoregulatory effects of MDPV depend on ambient temperature, so the current studies aimed to gauge the involvement of dopamine (DA), norepinephrine (NE), and serotonin (5-HT) in MDPV-induced locomotor stimulation and hyperthermia in the mouse at different ambient temperatures. Mice were pretreated with the selective 5-HT-reuptake inhibitor fluoxetine (3 mg/kg), the NE-reuptake inhibitor desipramine (3 mg/kg), the DA-reuptake inhibitor bupropion (10 mg/kg), or saline, followed by 10 mg/kg MDPV while thermoregulation and locomotor activity were monitored via radiotelemetry...

Bupropion, an antidepressant drug has been approved as a racemate containing equal amounts of R- and S- enantiomers. Recently, the chirality of bupropion has received significant attention in the delineation of stereoselective pharmacokinetic and disposition data. Although the non-stereoselective metabolism of bupropion was well established, the emerging data suggests that bupropion exhibits complex stereoselective metabolism, leading to the formation of various stereoisomeric metabolites. Along with the chiral pharmacokinetics of bupropion, hydroxybupropion, threohydrobupropion and erythrohydrobupropion, the metabolism data also provided insights into the roles of both CYP2B6 and CYP2C19 enzymes in the stereoselective disposition...
