BACKGROUND: Recently, several clinical studies have suggested a beneficial effect of a combination of antidepressants (ADs) with antipsychotic drugs in drug-resistant depression. Moreover, preclinical and clinical studies indicated a role of brain-derived neurotrophic factor (BDNF) in the pathology of depression, as well as in the mechanism of action of ADs. METHODS: In the present study, we investigated the effect of repeated administration of ADs, escitalopram, fluoxetine or mirtazapine and a low dose of risperidone (an atypical antipsychotic drug) given separately or in combination, on the mRNA and protein levels of BDNF or cAMP response element binding (p-CREB) in the hippocampus and frontal cortex of male Wistar rats...

Serotonin (5-HT) has been implicated as a key driver of liver fibrosis, acting via 5-HT2 receptor activation in the hepatic stellate cells. The current study was conducted to investigate the effects of mirtazapine, a 5-HT2A antagonist, in a mouse model of liver fibrosis. Mice received thioacetamide (TAA, 150mg/kg/biweekly, ip) for nine successive weeks for induction of liver fibrosis. Administration of mirtazapine significantly improved the plasma aminotransferases, reduced hepatic 5-HT concentration and ameliorated TAA-induced liver fibrosis, as demonstrated by reduced portal blood pressure, liver procollagen I content and α alpha smooth muscle actin expression...

A 7-year-old female golden retriever dog was presented with a 2-week history of coughing and inappetence. Examination, radiographs, and blood analysis showed classic evidence of blastomycosis, confirmed with the MVista EIA urine antigen test. A 2-month course of itraconazole and a course of mirtazapine, meloxicam, furosemide, and tetracycline resulted in a successful outcome.

Mirtazapine is a noradrenergic and specific serotoninergic antidepressant agent that stimulates norepinephrine and serotonin release while also blocking serotonin receptors (5-HT2 and 5-HT3). Although the drug is used extensively, at present we do not know of any fatal cases due to mirtazapine alone. On the contrary, the published literature describes several fatal poisoning cases related to the intake of mirtazapine together with other drugs. Here we describe a fatal case of mirtazapine self-poisoning, since the other drug detected (lorazepam), was within the therapeutic range...

Positive airway pressure (PAP) is the preferred treatment for obstructive sleep apnea (OSA), but adherence is low. Educational or ongoing supportive intervention improves the number of PAP adherent patients from the 50% to the 70% range. A common side effect of PAP is increased awakenings. This prospective trial examined baseline polysomnographically derived sleep efficiency and arousal index in PAP adherent and nonadherent patients, and in patients needing sedating medicines to attain PAP adherence versus those who did not need such medicines...

BACKGROUND: Depression is accompanied by activated neuro-oxidative and neuro-nitrosative pathways, while targeting these pathways has clinical efficacy in depression. This study aimed to investigate the effects of mirtazapine (MIRT) alone and combined with alpha-lipoic acid (ALA) against corticosterone (CORT) induced behavioral and oxidative alterations. METHODS: Male mice received vehicle or CORT 20mg/kg during 14 days. From the 15th to 21st days they were divided in groups administered: vehicle, MIRT 3mg/kg or the combinations MIRT+ALA100 or MIRT+ALA200...

Parkinson's disease (PD), a neurodegenerative disorder, is accompanied by various non-motor symptoms including depression and anxiety, which may precede the onset of motor symptoms. Selegiline is an irreversible monoamine oxidase-B (MAO-B) inhibitor, and is widely used in the treatment of PD and major depression. However, there are few reports about the effects of selegiline on non-motor symptoms in PD. The aim of this study was to explore the antidepressant and anxiolytic effects of selegiline, using CD157/BST1 knockout (CD157 KO) mouse, a PD-related genetic model displaying depression and anxiety, compared with other antiparkinsonian drugs and an antidepressant, and was to investigate the effects of selegiline on biochemical parameters in emotion-related brain regions...

There is increasing evidence of clinically relevant anti-inflammatory effects of monoaminergic antidepressants. PubMed and Ovid databases were searched systematically for the use and efficacy of antidepressants in association with 5 common inflammatory skin disorders: chronic urticaria, psoriasis, atopic dermatitis, other eczema, and alopecia areata. From January 1984 to June 2016, publications included a total of 1,252 dermatological patients in 28 trials or case reports. These unambiguously reported a reduced burden of dermatological symptoms in relation to treatment with antidepressants...

The current standard diagnostic approach for progressive multifocal leukoencephalopathy (PML) is to perform a DNA test to identify the presence of the JC virus in cerebrospinal fluid (CSF). A 32-year-old woman with a 5-year history of systemic lupus erythematosus developed right hemiplegia and motor aphasia. MRI revealed a large white matter lesion in the left frontal lobe. JC virus DNA was undetectable in the CSF, but a brain biopsy showed typical histopathology and a high DNA load of the JC virus. The patient was treated with mefloquine and mirtazapine, and is currently alive at 24 months after onset...

Relapse to cocaine use is a major problem in the clinical treatment of cocaine dependence. Antidepressant medications have been studied as potential therapeutic drugs to relieve a cocaine dependence disorder. Mirtazapine is an antidepressant implicated in reducing behavioral alterations induced by drugs of abuse. We have reported elsewhere that 30mg/kg mirtazapine administered for 30 days during cocaine extinction significantly attenuated the induction and expression of cocaine-induced locomotor sensitization and decreased the duration of the cocaine-induced locomotor effect...

PURPOSE: The role of glioma stem cells (GSCs) in cancer progression is currently debated; however, it is hypothesised that this subpopulation is partially responsible for therapeutic resistance observed in glioblastoma multiforme (GBM). Recent studies have shown that the current treatments not only fail to eliminate the GSC population but even promote GSCs through reprogramming of glioma non-stem cells to stem cells. Since the standard GBM treatment often requires supplementation with adjuvant drugs such as antidepressants, their role in the regulation of the heterogeneous nature of GSCs needs evaluation...

Antidepressant drugs are widely used in the treatment of different psychiatric disorders, as well as in conjunction with antipsychotics for the treatment of major depressive disorder. In this study, a simple and rapid ultrasound-assisted low-density solvent dispersive liquid-liquid microextraction (UA-LDS-DLLME) method was developed for the simultaneous determination of 12 new antidepressants (norfluoxetine, fluoxetine, fluvoxamine, agomelatine, mirtazapine, moclobemide, melitracen, N-desmethylmirtazapine, maprotiline, sertraline, citalopram, paroxetine) and 2 antipsychotics (clozapine and haloperidol) in human whole blood by gas chromatography-mass spectrometry (GC-MS)...

The cannabis withdrawal syndrome (CWS) is a criterion of cannabis use disorders (CUDs) (Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition) and cannabis dependence (International Classification of Diseases [ICD]-10). Several lines of evidence from animal and human studies indicate that cessation from long-term and regular cannabis use precipitates a specific withdrawal syndrome with mainly mood and behavioral symptoms of light to moderate intensity, which can usually be treated in an outpatient setting...

Major Depressive Disorder (MDD, ICD-10: F-33) is a prevalent illness in which the pathogenic mechanism remains elusive. Recently an important role has been attributed to neuro-inflammation, and specifically the NLRP3-inflammasome complex, in the pathogenesis of MDD. This suggests a key role for immunomodulation as a key pathway in the treatment of this disorder. This study evaluates the involvement of nine common antidepressants in the NLRP3-inflammasome complex (fluoxetine, paroxetine, mianserin, mirtazapine, venlafaxine, desvenlafaxine, amitriptyline, imipramine and agomelatine), both in in vitro THP-1 cells stimulated by ATP, and in a stress-induced depressive animal or MDD patients...

BACKGROUND: This case illustrates previously undiagnosed dissociative identity disorder (DID) in a middle-aged female with extensive childhood trauma, who was high functioning prior to a trigger that caused a reemergence of her symptoms. The trigger sparked a dissociative state, attempted suicide, and subsequent inpatient psychiatric hospitalization. OBJECTIVE: Practitioners should include in their differential and screen for undiagnosed DID in patients with episodic psychiatric hospitalizations refractory to the standard treatments for previously diagnosed mental illnesses...

Mirtazapine is a commonly used drug indicated for the treatment of severe depression. It works as a presynaptic α2-adrenoreceptor antagonist that increases central noradrenergic and serotonergic neurotransmission, and it is metabolized by the p450 cytochrome oxidase system. There is evidence within the literature to suggest a link between antidepressants and increased liver enzymes, although case reports demonstrating a link between mirtazapine specifically and steatosis are sparse. Here, we present a case of mirtazapine-induced steatosis in a 48-year-old office worker...
