Bupropion (BUP) overdose commonly causes generalized seizures and central nervous system depression. The case of a 28-year-old woman who died from a massive lethal overdose with sustained-release bupropion (Wellbutrin® 300 mg) is herein presented. The autopsy revealed the presence of a pharmacobezoar consisting of at least 40 tablets in the stomach. Determination of bupropion and its active metabolites (hydroxybupropion, threobupropion, erythrobupropion) was achieved by a liquid chromatographic mass spectrometry (LC-MS/MS) method...

Acute drug-induced dystonia is commonly associated with antipsychotic drugs, antidepressants, antiemetics, and other medications. Bupropion (Wellbutrin and Zyban) is one of the most frequently prescribed antidepressants in the United States and Canada and smoking cessation aid. However, only few reported cases have been published of acute dystonia including dystonia after discontinuation of bupropion and even after a single dose of bupropion. Here, we report another case concerning an acute dystonia resulting from bupropion after dose escalation...

INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent neuropsychiatric disorders of childhood and adolescence. Stimulants are usually the first choice of drug; however, as many as 20% of patients do not respond to them. Stimulants may also worsen comorbid sleep, mood, and anxiety disorders, and they are associated with problems of misuse and diversion. Bupropion, a dopamine and norepinephrine reuptake inhibitor, is a promising nonstimulant alternative with reports of positive outcomes for ADHD management in both adolescent and adult populations...

Obesity is a disease that has historically eluded effective medical therapy. Prior to 2012, phentermine and orlistat were the only medications available to treat obesity in the USA, with phentermine approved only for short-term use. However, as of 2015, the repertoire of pharmacological agents available to treat obesity has greatly expanded to include four new drugs: lorcaserin, phentermine/topiramate extended release (ER), naltrexone ER/wellbutrin ER and liraglutide. Each has a unique mechanism of action and all are intended for long-term use...

OBJECTIVES: Depression is a rapidly growing issue in the United States. There are many drug classes that may be used to treat depression, including the selective serotonin-reuptake inhibitors (SSRIs) citalopram (Celexa®) and sertraline (Zoloft®), as well as the aminoketone bupropion (Wellbutrin®). However, therapeutic efficacy and treatment success is often variable, requiring changes in dosing regimens or drug selection. Methods for drug quantification can become important tools in the assessment of drug efficacy to optimize treatment regimens...

BACKGROUND: Bupropion inhibits the reuptake of norepinephrine and dopamine, which are involved in the pathogenesis of affective, cognitive, and psychomotor impairment in schizophrenia. Because of reports on bupropion-associated psychoses, it is reluctantly used in schizophrenic patients. Risks and benefits, however, have never been comprehensively reviewed. OBJECTIVE: The objectives of this study were to evaluate the efficacy of bupropion on depression, negative symptoms, cognition, and smoking habits in schizophrenia and to appraise safety aspects...

Wellbutrin (bupropion•HCl), a novel antidepressant in current clinical use, was evaluated in two pharmacokinetic, steady-state studies. Bupropion (B), and its 3 basic metabolites, hydroxy-t-butyl-bupropion (HB), erythro-hydro-bupropion (EB), and threo-hydro-bupropion (TB) plasma concentrations were determined by a high pressure liquid chromatographic method at several time points on the fourteenth day of each dosing regimen. Based on mean AUC and Cmax ratios from 22 male subjects, dose proportionality was observed between 100 and 150 mg t...

Appropriate management of patients in pain clinics can be complex and sometimes confusing because providers must correctly interpret multiple sources of patient information. The correct interpretation of laboratory results is essential to guide subsequent patient treatment and management; however, laboratory and clinical pictures can appear to be conflicting in cases of substance abuse. Incorrect interpretation of laboratory results can multiply negative impacts on clinical outcomes and may lead to patient harm or death...

The effects of sex, ethnicity, and genetic polymorphism on hepatic CYP2B6 (cytochrome P450 2B6) expression and activity were previously demonstrated in vitro. Race/ethnic differences in CYP2B6 genotype and phenotype were observed only in women. To identify important covariates associated with interindividual variation in CYP2B6 activity in vivo, we evaluated these effects in healthy volunteers using bupropion (Wellbutrin SR GlaxoSmithKline, Research Triangle Park, NC) as a CYP2B6 probe substrate. A fixed 150-mg oral sustained-release dose of bupropion was administered to 100 healthy volunteers comprising four sex/ethnicity cohorts (n = 25 each): Caucasian men and Caucasian, African American, and Hispanic women...

Towards addressing the knowledge gap of how bupropion interacts with the dopamine transporter (DAT) and nicotinic acetylcholine receptors (nAChRs), a ligand was synthesized in which the chlorine of bupropion was isosterically replaced with an iodine and a photoreactive azide was added to the 4'-position of the aromatic ring. Analog (±)-3 (SADU-3-72) demonstrated modest DAT and α4β2 nAChR affinity. A radioiodinated version was shown to bind covalently to hDAT expressed in cultured cells and affinity-purified, lipid-reincorporated human α4β2 neuronal nAChRs...

BACKGROUND: Medicaid programs' spending on antidepressants increased from $159 million in 1991 to $2 billion in 2005. The National Institute for Health Care Management attributed this expenditure growth to increases in drug utilization, entry of newer higher-priced antidepressants, and greater prescription drug insurance coverage. Rising enrollment in Medicaid has also contributed to this expenditure growth. OBJECTIVES: This research examines the impact of specific events, including branded-drug and generic entry, a black box warning, direct-to-consumer advertising (DTCA), and new indication approval, on Medicaid spending on antidepressants...

We investigated antidepressant prescriptions and reasons for use. According to our data, the top 10 molecules represent approximately 95% of total antidepressant prescriptions for both primary care physicians (PCPs) and psychiatrists. The primary difference between PCPs and psychiatrists was the increased use of buproprion and tricyclics/tetracyclics by psychiatrists. The selective serotonin reuptake inhibitors (SSRIs) and other newer antidepressants such as venlafaxine (Effexor) and buproprion (Wellbutrin) are used to treat depression, anxiety, and bipolar disorders...

The Food and Drug Administration (FDA) approved the New Drug Application for Wellbutrin sustained release (SR) 100 mg tablets on October 4, 1996. However, by 1998, the FDA expressed concern about the stability of this drug product based on an increase in the dissolution profile on storage. Data submitted in the annual report showed that this drug product could not meet the expiry of 18 months at the International Committee on Harmonization storage condition of 25 degrees C/60% relative humidity. The FDA mandated a 12-month expiry and GlaxoWellcome tightened this further by instituting an expiry of 9 months...
