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...

Drug and behavioral addictions have overlapping features, e.g., both manifest preference for larger, albeit costlier, reinforcement options in cost/benefit decision-making tasks. Our prior work revealed that the mixed-function serotonergic compound, mirtazapine, attenuates behaviors by rats motivated by abused drugs. To extend this work to behavioral addictions, here we determined if mirtazapine and/or ketanserin, another mixed-function serotonin-acting compound, can alter decision-making in rats that is independent of drug (or food)-motivated reward...

INTRODUCTION: Gastroparesis symptoms can be severe and debilitating. Many patients do not respond to currently available treatments. Mirtazapine has been shown in case reports to reduce symptoms in gastroparesis. AIM: To assess the efficacy and safety of mirtazapine in gastroparetic patients. METHODS: Adults with gastroparesis and poorly controlled symptoms were eligible. Participants were prescribed mirtazapine 15 mg PO qhs. Questionnaires containing the gastrointestinal cardinal symptom index (GCSI) and the clinical patient grading assessment scale (CPGAS) were completed by patients' pretreatment, at 2 weeks, and at 4 weeks...

Citalopram, mirtazapine and risperidone are frequently prescribed for psychiatric illnesses such as depression and psychosis or for aggressive behavior in elderly patients with dementia. The plasma concentrations vary greatly between patients, especially in elderly patients. Thus, therapeutic drug monitoring (TDM) increases the safety of antipsychotic treatment and a more rapid response to treatment may be achieved. To facilitate TDM, the objectives of this study were to develop and validate a reliable dried blood spot method to simultaneously quantify citalopram, mirtazapine and risperidone including its active metabolite 9-hydroxyrisperidone...

The differential diagnosis of non-convulsive status epilepticus (NCSE) is often complex due to a wide clinical variability of its presentation, including psychiatric manifestations. We report a 68 years old male with a history of depression treated with venlafaxine, mirtazapine, quetiapine and risperidone, presenting in the emergency room with confusion and generalized rigidity. A brain CT scan did not show lesions. A neuroleptic syndrome was initially suspected. At the third day the obtundation worsened and an electroencephalogram (EEG) was performed, which showed epileptiform abnormalities...

BACKGROUND: Relapse to cocaine use is a major problem in the clinical treatment of cocaine addiction. Antidepressants have been studied for their therapeutic potential to treat cocaine use disorder. Research has suggested that antidepressants attenuate both drug craving and the re-acquisition of drug-seeking and drug-taking behaviors. This study examined the efficacy of mirtazapine, an antidepressant/anxiolytic, in decreasing cocaine seeking in rats. METHODS: We used the cocaine self-administration paradigm to assess the effects of mirtazapine on rats trained to self-administer cocaine or food under a fixed-ratio schedule...

Aims and method To discern changes in body mass index (BMI) in patients on long-term antidepressant treatment in a general practice population and establish BMI changes in patients with and without a diagnosis of diabetes. We used a retrospective observational method and identified patients on four antidepressants of interest. We excluded those who did not have start and current BMI readings within the past 3 years and noted whether or not patients had a diagnosis of diabetes. Results Long-term treatment with citalopram, fluoxetine, mirtazapine and sertraline was associated with increased BMI in two-thirds of patients...

INTRODUCTION: Orally disintegrating tablets (ODTs) provide an important treatment option for pediatric, geriatric, and psychiatric patients. In our previous study, we have performed the initial studies for the formulation development and characterization of new ODT formulations containing a bitter taste drug, mirtazapine, coated with 6% (w/w) Eudragit® E-100 (first group of formulations, FGF) without taste evaluation. In present study, coating ratio of the drug was increased to 8% (w/w) (second group of formulations, SGF) to examine the effect of increased coating ratio of drug on in vitro characterization of the formulations including in vitro taste masking study...

The link between neurotransmitter-level effects of antidepressants and their clinical effect remain poorly understood. A single dose of mirtazapine decreases limbic responses to fearful faces in healthy subjects, but it is unknown whether this effect applies to complex emotional situations and dynamic connectivity between brain regions. Thirty healthy volunteers listened to spoken emotional narratives during functional magnetic resonance imaging (fMRI). In an open-label design, 15 subjects received 15mg of mirtazapine two hours prior to fMRI while 15 subjects served as a control group...

OBJECTIVE: Sedation/somnolence are major side effects of pharmacotherapies for depression, and negatively affect long-term treatment compliance in depressed patients. Use of mirtazapine (MIR), an atypical antidepressant approved for the treatment of moderate to severe depression with comorbid anxiety disorders, is associated with significant sedation/somnolence, especially in short-term therapy. Nonetheless, studies with human subjects suggest that MIR-induced sedation is transient, especially when high and repeated doses are used...

BACKGROUND: Fumaric acid esters (FAEs) are a systemic treatment for psoriasis considered to have a favorable long-term safety profile without an increased risk for immunosuppression. However, progressive multifocal leukoencephalopathy (PML), a rare, opportunistic viral infection of the central nervous system, has been linked anecdotally to FAE treatment. OBJECTIVE: to assess clinical features and outcomes of FAE-associated PML cases. METHODS: Systematic literature search in multiple databases up to February, 25(th) 2016 for reports of PML in psoriasis patients treated with FAEs...

A 40-year-old woman with bipolar disorder who was taking mirtazapine presented with mydriasis, abnormal diaphoresis, myoclonus and muscle rigidity after taking metocloplamide. Her medical history, which included the use of serotonergic agents, and the presence of symptoms including myoclonus and muscle rigidity were consistent with a diagnosis of serotonin syndrome (SS) according to the Hunter criteria. The symptoms diminished following three days of treatment with oral lorazepam and cyproheptadine and a reduced dose of mirtazapine...

OBJECTIVE: Because of concerns about potential associations between high doses of citalopram and QTc prolongation in adults, this study examined whether such associations are operant in children. We hypothesized that therapeutic doses of nontricyclic antidepressant medications (non-TCAs) prescribed to children would be cardiovascularly safe. STUDY DESIGN: The sample consisted of 49 psychiatrically referred children and adolescents 6 to 17 years old of both sexes treated with a non-TCA (citalopram, escitalopram, fluoxetine, paroxetine, sertraline, bupropion, duloxetine, venlafaxine, mirtazapine)...

BACKGROUND: Nitric oxide (NO) is a neurotransmitter that may be related to major depressive disorder (MDD) because the selective neuronal NO synthase (NOS) inhibitor, 7-nitroindazole, induces a dose-dependent antidepressant-like effect. NO modulates major neurotransmitters involved in the neurobiology of MDD, such as norepinephrine, serotonin, dopamine, and glutamate. In this study, we investigated the effects of antidepressants as NO modulators in acute and sub-chronic treatments. METHODS: Rats were injected with the SSRI paroxetine (PAR, 10 mg/kg), the SNRI milnacipran (MIL, 30 mg/kg), or the NaSSA mirtazapine (MIR, 10 mg/kg) for acute (1 h) or sub-chronic (3 weeks) treatment prior to analysis of nine brain regions (frontal cortex, temporal cortex, striatum, thalamus, hippocampus, midbrain, pons, cerebellum, and olfactory bulb)...
