PURPOSE: Agomelatine is a novel antidepressant drug suffering from an extensive first-pass metabolism leading to a diminished absolute bioavailability. The aim of the study is: first to enhance its absolute bioavailability, and second to increase its brain delivery. METHODS: To achieve these aims, the nasal route was adopted to exploit first its avoidance of the hepatic first-pass metabolism to increase the absolute bioavailability, and second the direct nose-to-brain pathway to enhance the brain drug delivery...

We describe a case of lower urinary system symptoms (LUSSs) and acute urinary retention that developed after treatment with a low dose of venlafaxine. A 48-year-old male patient was admitted to our clinic because of difficulty urinating, an intermittent stream, and trickling at the end of urination, together with urinary retention that had started about 45 days ago. The patient had been taking venlafaxine for the previous 6 months. The drug had been prescribed by the psychiatry department for a diagnosis of major depression, and the dose had been increased from 75 mg/day to 150 mg/day 1...

Switching antidepressant therapy is a recommended strategy for depressed patients who neither respond to nor tolerate an initial pharmacotherapy course. This paper reviews the efficacy and tolerability of switching to vortioxetine. All three published studies of patients with major depressive disorder (MDD) switched from SSRI/SNRI therapy to vortioxetine due to lack of efficacy or tolerability were selected. Vortioxetine was evaluated versus agomelatine directly (REVIVE) and versus sertraline, venlafaxine, bupropion, and citalopram in an indirect treatment comparison (ITC) from switch studies retrieved in a literature review...

In view of well-evidenced antiepileptic effects of melatonin and few reports of anticonvulsant action of agomelatine, the present study investigated whether agomelatine protects against pentylenetetrazole (PTZ)-induced kindling in mice and kindling-associated oxidative stress, depression, and impairment of spatial memory. In order to explore whether effects are mediated by melatonergic or serotonergic mechanisms, 1-(m-chlorophenyl) piperazine (mCPP), selective 5HT2c receptor agonist and luzindole, melatonergic receptor antagonist, were taken as pharmacological tools...

BACKGROUND: Anhedonia is a core symptom of major depression and a key prognostic factor that is often poorly explored in clinical trials of major depressive disorder (MDD). Beyond symptomatic remission, psychosocial functioning also reveals difficulty in achieving remission in patients with MDD. The main objective of this study was to explore the interrelationships between social functioning and anhedonia on a longitudinal basis. METHODS: In total, 1570 outpatients treated for MDD with agomelatine were included...

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)...

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...

Recent studies about the novel antidepressant agomelatine, which is a mixed MT1 and MT2 melatonin receptor agonist and 5HT2C serotonin receptor antagonist possessing an anticonvulsant and neuroprotective action, suggest that it may have potential to contribute against epileptogenesis and epilepsy-induced memory impairment. In order to ascertain whether protection of some brain structures could suppress epileptogenesis, in the present study, we evaluated the effect of chronic post-status treatment with agomelatine on epileptogenesis, behavioral and neuronal damage induced by kainate acid (KA) status epilepticus (SE)...

The present study was designed to assess the bioequivalence of two agomelatine formulations (25-mg tablets) in healthy Chinese male subjects. This single-dose, open-label, randomized, four-way replicate study with a 1-week washout period was conducted in 60 healthy Chinese male volunteers under fasting conditions. Blood samples were collected over a 12-h period after a single dose of the 25-mg agomelatine test (T) formulation or a reference (R) formulation, and the drug concentrations were assayed by liquid chromatography tandem mass spectrometry (LC-MS/MS)...

The present paper reports in parallel the findings of the two phase III trials that evaluated the efficacy of agomelatine in older depressed patients. It describes how the particular methodological innovations (particularly in relation to patient selection, design and accuracy of diagnosis of depression) introduced in study 2 have improved the quality of recruitment of patients and the assay sensitivity. Study 1 lacked assay sensitivity, and among the many differences with study 2, the inclusion of unexpected mildly ill patients could have inflated the placebo response...

Chronic stress is known to induce not only anxiety and depressive-like phenotypes in mice but also cognitive impairments, for which the action of classical antidepressant compounds remains unsatisfactory. In this context, we investigated the effects of chronic social defeat stress (CSDS) on anxiety-, social- and cognitive-related behaviors, as well as hippocampal Bdnf, synaptic plasticity markers (PSD-95, Synaptophysin, Spinophilin, Synapsin I and MAP-2), and epigenetic modifying enzymes (MYST2, HDAC2, HDAC6, MLL3, KDM5B, DNMT3B, GADD45B) gene expression in C57BL/6J mice...

OBJECTIVES: Several studies reported that antidepressant drugs have immune-regulatory effects by acting on specific inflammatory mediators. However, considering the highly complex nature of the inflammatory response, we have adopted an unbiased genome-wide strategy to investigate the immune-regulatory activity of the antidepressant agomelatine in modulating the response to an acute inflammatory challenge. METHODS: Microarray analysis was used to identify genes modulated in the ventral hippocampus of adult rats chronically treated with agomelatine (40 mg/kg, os) before being challenged with a single injection of lipopolysaccharide (LPS; 250 μg/kg, i...

Fibromyalgia (FM) is a syndrome that affects muscles and soft tissues. Presenting symptoms include chronic muscle pain, fatigue, sleep problems and psychological symptoms, including depression and anxiety. There exists strong evidence of a comorbidity between FM and Bipolar Disorder (BD). In this study, papers from 2006 to February 2016 that examined the comorbidity and etiological similarities of FM and BD were reviewed, as well as the therapeutic implications of these findings. The reviewed articles showed that an adequate psychiatric screening for BD is recommended in FM patients with depressive symptoms, in order to decrease administration of antidepressants for BD, due to the lack of proven efficacy, and to limit antidepressant-induced mania...

Agomelatine is efficacious in reducing symptoms and preventing relapse in placebo-controlled trials in generalised anxiety disorder (GAD). Nevertheless, fixed dose studies of agomelatine in GAD have not been undertaken. To determine the minimally effective optimal dose of agomelatine in GAD, the efficacy of two doses of agomelatine (10 and 25mg/day) was investigated in a 12-week, placebo-controlled, double-blind, international study in patients with a primary diagnosis of GAD. The primary outcome measure was the Hamilton Anxiety scale (HAM-A)...
