Nefazodone is an anti-depressant that interacts with a wealth of pharmacological targets, including some that may exert anti-dyskinetic and anti-psychotic effects in Parkinson's disease (PD), notably serotonin 1A and 2A receptors. In this study, we sought to determine the effect of nefazodone on L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesia and psychosis-like behaviours (PLBs) in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-lesioned primate. Six common marmosets developed parkinsonism following administration of MPTP, after which they were treated chronically with L-DOPA to induce stable dyskinesia and PLBs...

The potential consequences of drug-drug interactions on the excretion profile of the anabolic androgenic steroid methandienone (17β-hydroxy-17α-methylandrosta-1,4-dien-3-one) are discussed. More specifically, we have evaluated by in vitro and in vivo experiments the effects of 7 non-prohibited drugs (fluconazole, ketoconazole, itraconazole, miconazole, fluoxetine, paroxetine, and nefazodone) on the main metabolic pathways of methandienone. These are selected among those most commonly used by the athletes...

This study examined the ability of several human pharmaceuticals to modulate hepatic piscine CYP-mediated monooxygenase activities. Effects of six pharmaceuticals: diclofenac, sulfamethoxazole, tramadol, carbamazepine, venlafaxine and nefazodone, were investigated in vitro in rainbow trout hepatic microsomes. The reactions of 7-ethoxyresorufin-O-deethylase (EROD) and benzyloxy-4-trifluoromethylcoumarin-O-debenzyloxylase (BFCOD), were used as markers for hepatic CYP1A and CYP3A-like activities, respectively...

The piperazine derivatives correspond to an extensive chemical class of compounds with numerous neuropharmacological activities, including antidepressant (e.g., nefazodone, trazodone) and anxiolytic (e.g., buspirone) properties. Therefore, aiming to identify a new antidepressant and antianxiety lead-compound, our group designed, synthesized, and investigated the effects of a new piperazine compound, namely, LQFM104, on the behavior of mice. Male albino Swiss mice were treated with LQFM104 prior to predictive behavioral tests as open field (OFT), elevated plus maze (EPM), forced swimming (FST), and tail suspension tests (TST)...

BACKGROUND AND AIM: The occurrence of drug induced liver injury (DILI) is the most common reason of post-marketing withdrawals. DILI in humans is difficult to predict using in vitro cytotoxicity screening and animal studies. A review of hepatotoxicity data was performed with the aim of identifying relevant factors that could have predicted the occurrence of serious DILI. METHODS: The drugs withdrawn from the market due to hepatotoxicity in Europe and/or in USA either by marketing authorization holders or by Regulatory agencies from 1997 to 2016 were selected...

D S Danilov
Based on the original literature, the author for the first time describes a history of selective serotonergic antidepressants simultaneously inhibiting the serotonin reuptake and directly interacting with serotonin receptors. A history of creation and introduction of their main representatives is presented. A history of investigation of their neurochemical activity is analyzed in details. The history of the evolution of their classifications is systemized. The data presented suggest the rationale for unifying all selective serotonergic antidepressants, simultaneously inhibiting the serotonin reuptake and directly interacting with serotonin receptors (trazodone, etoperidone, nefazodone, vilazodone, vortioxetine), in one group of 'multimodal serotonergic antidepressants'...

OBJECTIVE: Theories posit that chronically depressed individuals have hostile and submissive interpersonal styles that undermine their interpersonal effectiveness and contribute to the cause and maintenance of their depression. Recent findings support this theory and demonstrate that chronically depressed patients' interpersonal impacts on their therapist become more adaptive (i.e., less hostile and submissive, and more friendly and assertive) during a targeted chronic depression treatment: cognitive-behavioral analysis system of psychotherapy (CBASP)...

Nefazodone, an antagonist for the 5-hydroxytryptanine receptor, has been used for the treatment of depression. Acute liver injury has been documented to be associated with the use of nefazodone; however, the mechanisms of nefazodone-induced liver toxicity are not well defined. In this report, using biochemical and molecular analyses, we characterized the molecular mechanisms underlying the hepatotoxicity of nefazodone. We found that nefazodone induced endoplasmic reticulum (ER) stress in HepG2 cells, as the expression of typical ER stress markers, including CHOP, ATF-4, and p-eIF2α, was significantly increased, and splicing of XBP1 was observed...

Symptoms of anxiety and depression often appear together in patients, either as 2 discrete disorders, such as major depressive disorder and panic disorder, or as a combination of symptoms not meeting criteria for specific disorders. The social, economic, occupational and medical costs of such comorbid anxiety and depression can be enormous, affecting both the individual and society.The clinician must be creative when treating patients with mixed anxiety and depressive symptoms; psychopharmacological treatment can involve the use of a variety of mono- and polytherapies...

Recognition of the role of active metabolites in mediating therapeutic and/or adverse effects of many antidepressants is an important part of understanding the mechanisms of action of these medications. While virtually all antidepressants except lithium undergo extensive hepatic metabolism, the profile of activity of the resulting breakdown products varies considerably.The metabolites of some antidepressants share the primary biochemical actions of their parent compounds and appear to contribute to the therapeutic efficacy of those medications...

INTRODUCTION: Many antidepressants are indicated for the treatment of major depression. Two network meta-analyses have provided the most comprehensive assessments to date, accounting for both direct and indirect comparisons; however, these reported conflicting interpretation of results. Here, we present a protocol for a systematic review and network meta-analysis aimed at updating the evidence base and comparing all second-generation as well as selected first-generation antidepressants in terms of efficacy and acceptability in the acute treatment of major depression...

REVIEW
Maria Dettoraki, Marilita M Moschos
Multifocal electroretinography (mfERG) is an objective, noninvasive examination for the assessment of visual function. It enables the stimulation of multiple retinal areas simultaneously and recording of each response independently, providing a topographic measure of retinal electrophysiological activity in the central 40-50° of the retina. A clinical application of mfERG represents the assessment of retinal toxicity associated with systemic medications. Drug-induced retinopathy represents a disease that, although not common, requires early recognition: if not detected early, it may progress and cause irreversible retinal dysfunction with subsequent visual impairment...

Nefazodone (NEF) is an antidepressive agent that was widely used in the treatment of depression until its withdrawal from the market, due to reports of liver injury and failure. NEF hepatotoxicity has been associated with mitochondrial impairment due to interference with the OXPHOS enzymatic activities, increased ROS generation and decreased antioxidant defenses. However, the mechanisms by which NEF induces mitochondrial dysfunction in hepatocytes are not completely understood. Here, we investigated the mitochondrial mechanisms affected upon NEF exposure and whether these might be linked to drug hepatotoxicity, in order to infer liabilities of future drug candidates...
