We present a simple and fast high-performance liquid chromatography method with fluorescence detection for the determination of the antiepileptic drug perampanel in human plasma. The chromatographic separation was performed on a Kinetex PFP (100 × 2.6 mm, 4.6 µm) column, using a mobile phase of sodium acetate 0.03 M pH 3.7 and acetonitrile (40/60, v/v), at a flow rate of 0.8 mL/min. Total chromatography time for each run was 5 min. Sample preparation (250 µL) involved only one simple precipitation step by acetonitrile spiked with mirtazapine as internal standard...

Nicotinic acetylcholine receptors (nAChRs) and zinc are associated with regulation of mood and related disorders. In addition, several antidepressants inhibit muscle and neuronal nAChRs and zinc potentiates inhibitory actions of them. Moreover, mirtazapine (a noradrenergic, serotonergic and histaminergic antidepressant) inhibits muscarinic AChRs and its effects on nAChRs are unknown. Therefore, we studied the modulation of muscle α1β1γd nAChRs expressed in oocytes and native α7-containing nAChRs in hippocampal interneurons by mirtazapine and/or zinc, using voltage-clamp techniques...

BACKGROUND: To uncover pharmacokinetic interactions between venlafaxine and doxepin or mirtazapine in a naturalistic sample. METHODS: A therapeutic drug monitoring database containing plasma concentrations of venlafaxine (VEN) and its active metabolite O-desmethylvenlafaxine (ODVEN) was analyzed. We included 1067 of 1594 patients in the analysis. Three study groups were considered; a group of patients under venlafaxine without confounding medications, V0 (n = 905), a group of patients co-medicated with doxepin, VDOX (n = 25) and a second group, co-medicated with mirtazapine, VMIR, n = 137...

A 69-year-old woman presented with a cortical hand syndrome progressing over several weeks. MRI brain showed characteristic appearances of progressive multifocal leukoencephalopathy (PML), confirmed by detection of the JC virus in CSF, despite the absence of any evidence of immunosuppression. Treatment with mirtazapine, mefloquine and cidofovir did not affect the progression of the disease, which was fatal within 7 months of presentation. This report adds to the small case literature that suggests that PML can occur in immunocompetent people, albeit extremely rarely...

OBJECTIVE: To assess the risk of seizure associated with antidepressant use among patients with depressive disorders. METHODS: Individuals visiting the emergency department or hospitalized because of new-onset seizure (ICD-9-CM diagnostic code 345 or 780.3; our primary study outcome) after receiving antidepressants for depressive disorders, were identified from a Taiwanese total population health insurance database. Using a case-crossover study design, relative risk of antidepressant-related seizure was estimated by comparing the rates of antidepressant exposure during the case periods vs control periods...

65-year-old liver transplant recipient presented with progressive neurologic dysfunction. CSF analysis revealed high JC virus load and MRI findings suggested the diagnosis of progressive multifocal leukoencephalopathy (PML). Cidofovir and mirtazapine were initiated and patient's regular immunosuppressants were reduced. Subsequently patient developed left sided hemiplegia, drowsiness and severe neglect syndrome. MRI revealed enlargement of PML lesions with contrast enhancement and worsening of oedema, consistent with immune reconstitution inflammatory syndrome (IRIS)...

BACKGROUND: Optimal anti-epileptic drug (AED) treatment maximises therapeutic response and minimises adverse effects (AEs). Key to therapeutic AED treatment is adherence. Non-adherence is often related to severity of AEs. Frequently, patients do not spontaneously report, and clinicians do not specifically query, critical AEs that lead to non-adherence, including sexual dysfunction. Sexual dysfunction prevalence in patients with epilepsy ranges from 40 to 70%, often related to AEDs, epilepsy or mood states...

BACKGROUND: The Hamilton Depression Rating Scale (HAM-D) and the Montgomery Asberg Depression Rating Scale (MADRS) are scales used frequently to rate the symptoms of depression. There are many situations in which it is important to know what a given total score or a percent reduction from baseline score of one scale means in relation to the other scale. METHOD: We used the equipercentile linking method to identify corresponding scores of simultaneous HAM-D and MADRS ratings in 4388 patients from 31 mirtazapine trials in major depressive disorder...

Background: Platelet derived growth factor is integral to maintenance of blood brain barrier, increases in response to blood brain barrier disruption, and may reflect neuroinflammation. Based on previous reports of better outcomes with dopaminergic antidepressants in depressed patients with elevated inflammatory biomarkers, we hypothesize that elevated peripheral platelet derived growth factor levels can serve as a powerful biomarker for selecting dopaminergic antidepressants. Methods: Platelet derived growth factor, basic fibroblast growth factor, and granulocyte colony stimulating factor were measured as part of Bioplex Pro human cytokine 27-plex kit in participants of the Combining Medications to Enhance Depression Outcomes trial who provided baseline plasma (n=166) and were treated with either bupropion-plus-escitalopram, escitalopram-plus-placebo, or venlafaxine-plus-mirtazapine...

Antidepressants are routinely used by General Practitioners (GP) as well as Psychiatrists to treat Depression. They are tolerated well. However, in certain patient populations, they are associated with SIADH (Syndrome of Inappropriate Anti-Diuretic Hormone Secretion) and Hyponatremia. Various research studies have shown that all antidepressants are associated with Hyponatremia. Hyponatremia as a side effect of antidepressant therapy is more commonly seen in old age, chronic Kidney disease and Hypothyroidism...

Anxiety disorders are common in the elderly. Additionally, anxiety symptoms often accompany co-morbid psychiatric, medical, as well as neurodegenerative diseases in the older population. Anxiety in the elderly, often accompanied by depression, can lead to worsening physical, cognitive and functional impairments in this vulnerable population. Antidepressants are considered first line treatment. Both SSRIs and SNRIs are efficacious and well-tolerated in the elderly. Some SSRIs are strong inhibitors of the cytochrome P450 hepatic pathway whereas others have less potential for drug interaction...

BACKGROUND: Antidepressants are associated with adverse effects such as sedation and hypotension, which can result in falls and fractures. Few studies have assessed the risk of hip fracture due to mirtazapine, and no known studies have assessed whether the risk of hip fracture is higher in patients taking other antidepressant medicines in combination with mirtazapine. OBJECTIVES: This study aimed to examine the risk of hip fracture in older people due to mirtazapine use as well as switching between or concurrently using mirtazapine and other antidepressants...

PURPOSE: Cancer patients are often prescribed antidepressants, but little data is available about whether the type and dose are similar to prescriptions to patients with other chronic diseases. This study compared the prescription practices of antidepressants to cancer and non-cancer inpatients at a major Australian tertiary hospital and assessed side effects and potential drug-drug interactions. METHODS: Inpatients diagnosed with cancer within the past 12 months and prescribed antidepressants were age and gender matched to inpatients with other chronic disease conditions...

Mirtazapine is an antidepressant with prominent antioxidant effects. Chrysin, a natural flavone, exhibits multiple pharmacological actions. This study was designed to investigate the potential protective effects of chrysin and mirtazapine against nitrofurazone-induced testicular damage in rats. Possible underlying mechanisms such as oxidative stress, inflammation and apoptosis were also investigated. Testicular damage was induced by oral administration of nitrofurazone (50mg/kg/day) for two weeks. Chrysin (25 and 50mg/kg/day, p...

BACKGROUND: Sleep disturbances, in particular insomnia, represent a common problem in children with neurodevelopmental disabilities (NDDs). Currently, there are no approved medications for insomnia in children by the US Food and Drug Administration or European Medicines Agency and therefore they are prescribed off-label. We critically reviewed pediatric literature on drugs as well as nonpharmacological (behavioral) interventions used for sleep disturbances in children with NDDs. METHODS: PubMed, Ovid (including PsycINFO, Ovid MEDLINE(®) , and Embase), and Web of Knowledge databases were searched through February 12, 2017, with no language restrictions...

BACKGROUND: In register-based pharmacoepidemiological studies, construction of drug exposure periods from drug purchases is a major methodological challenge. Various methods have been applied but their validity is rarely evaluated. Our objective was to conduct an expert-opinion based evaluation of the correctness of drug use periods produced by different methods. METHODS: Drug use periods were calculated with three fixed methods: time windows, assumption of one Defined Daily Dose (DDD) per day and one tablet per day, and with PRE2DUP that is based on modelling of individual drug purchasing behavior...

Depressed patients often complain of sleep disturbance. Routine antidepressive strategies sometimes fail to deal with this intractable issue. Indeed, the supplementation of sleep promoting antidepressants (eg, trazodone, mirtazapine, and agomelatine) is prevalent in clinical practice. However, the combination of different antidepressants may increase the affective lability. Herein, we document a patient with unipolar depression who was compliant with sertraline treatment and who dramatically switched to mania after adding trazodone as a sleeping aid...
