Administration of bupropion [(±)-2-(tert-butylamino)-1-(3-chlorophenyl)propan-1-one] and its preformed active metabolite, hydroxybupropion [(±)-1-(3-chlorophenyl)-2-[(1-hydroxy-2-methyl-2-propanyl)amino]-1-propanone], to rats with measurement of unbound concentrations by quantitative microdialysis sampling of plasma and brain extracellular fluid was used to develop a compartmental pharmacokinet...

CONTEXT African Americans disproportionately experience greater smoking attributable morbidity and mortality. Few clinical trials for smoking cessation in African Americans have been conducted, despite a different profile of both smoking and quitting patterns. OBJECTIVE To compare a sustained-release form of bupropion hydrochloride (bupropion SR) with placebo for smoking cessation among Afric...

Major depressive disorder (MDD) and Parkinson's disease (PD) share symptoms such as tremor. Bupropion, a norepinephrine-dopamine reuptake inhibitor, shows weak dopamine transporter (DAT) occupancy. We report here on a patient with MDD whose hand tremors might have been misdiagnosed as PD by single-photon emission computed tomography (SPECT) under bupropion use. A 66-year-old male patient with M...

Since antiretroviral drugs are known to inhibit many cytochrome P450 isoforms, the inhibition of CYP2B6 by non-nucleoside reverse transcriptase inhibitors and viral protease inhibitors was studied in vitro in human liver microsomes using bupropion hydroxylation as the CYP2B6 index reaction. Mean IC(50) values (microM) for inhibition of bupropion hydroxylation were: nelfinavir (2.5), ritonavir (...

The purpose of this paper was to investigate the efficacy of bupropion and varenicline for treating nicotine dependence as reported in the published studies. We analysed 435 journal articles identified in Pubmed data base with “nicotine, dependence, bupropion / varencline” included in abstract. The “human” filter was applied. 20 efficacy studies were selected and included for evaluation in this...

The management and diagnosis of drug-induced liver injury (DILI) is often challenging, particularly when patients are taking multiple medications. We present a 29-year-old African American man who presented with jaundice and malaise after starting bupropion and doxycycline 2 weeks prior. He was found to have acute hepatocellular drug-induced liver injury with autoimmune features, and made a com...

The purpose of the present study was to administer an acute dose of the dual dopamine norepinephrine reuptake blocker bupropion in freely moving rats and to monitor the extracellular neurotransmitter concentrations in the hippocampus via in vivo microdialysis and the peripheral hormonal concentrations via catheterization. A microdialysis probe was inserted in the hippocampus, and samples for se...

BACKGROUND Antidepressant-induced sexual dysfunction (SD) is a common problem, associated with a significant risk of non-adherence. Selective Serotonin Reuptake Inhibitors (SSRIs) are associated with a substantial risk of SD. Only 10 % of patients show spontaneous improvement during follow up period. OBJECTIVES This study aimed to compare two proposed medication (bupropion vs. amantadine) in ...
