We report a likely false-positive phencyclidine (PCP) result detected with a urine drug screen (UDS) (Medtox, St Paul, Minnesota, USA) in the setting of therapeutic desvenlafaxine (Pristiq) use. Desvenlafaxine (O-desmethylvenlafaxine) is the active metabolite of venlafaxine (Effexor). Prior reports have confirmed venlafaxine use resulting in a false-positive for PCP on a UDS. However, there has been a paucity of reporting of commercially available desvenlafaxine formulations (Pristiq, Khedezla) resulting in false-positives for PCP on a UDS...

INTRODUCTION: Work-related disability and productivity loss in Major Depressive Disorder (MDD) are critical determinants of patient quality of life and contribute significantly to the human and economic costs of MDD. Notwithstanding the return to work and pre-morbid levels of functioning as a critical therapeutic objective among individuals with MDD, it is unclear whether antidepressant treatment significantly and reliably improves measures of workplace functioning. Herein, we investigate to what extent antidepressant treatment improves workplace functioning among adults with MDD...

INTRODUCTION: Management of severe vasoplegic shock in overdose can be very challenging. We describe a case of severe refractory vasodilatory shock in poisoning where methylene blue (MB) was used with success. However, the patient subsequently developed severe Serotonin Syndrome (SS) as a result of an interaction between serotonergic drugs and MB. CASE REPORT: A 15-year-old male developed severe vasoplegic shock 1.5 hours after overdosing on several different medications including quetiapine slow release, quetiapine immediate release, desvenlafaxine slow release, venlafaxine, amlodipine, ramipril, fluoxetine, promethazine and lithium...

INTRODUCTION: Jitteriness syndrome (JS) is a poorly understood but important adverse effect of antidepressant drugs. This study examined the incidence and pattern of antidepressant-related JS and its predictors. METHODS: 209 patients diagnosed with any anxiety or depressive disorder and started on mirtazapine, sertraline, desvenlafaxine, escitalopram or fluoxetine were assessed at baseline, after 2 weeks, and after 6 weeks with psychopathology rating scales and for predefined categories of JS...

Depression is a debilitating psychiatric condition that remains the second most common cause of disability worldwide. Currently, depression affects more than 4 per cent of the world's population. Most of the drugs intended for clinical management of depression augment the availability of neurotransmitters at the synapse by inhibiting their neuronal reuptake. However, the therapeutic efficacy of antidepressants is often compromised as they are unable to reach brain by the conventional routes of administration...

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...

The forced swim test (FST) is a commonly used preclinical animal behavioural model for prediction of antidepressant activity in humans. While the FST may qualitatively predict efficacy, less is known about the quantitative translation of FST data to human efficacious doses. Assessing quantitative translation allows better predictions of human efficacious doses and a higher chance of success in the drug development process. Dose-response and time-course FST experiments were carried out on mice using four marketed antidepressants (citalopram, desipramine, bupropion, desvenlafaxine) in addition to ketamine, all with varying mechanisms of action...

BACKGROUND: Anxiety and depression are common mental health disorders that are responsible for considerable societal burden. There are no data on cost-efficacy and medication compliance related to the treatment of these disorders in rural India. MATERIALS AND METHODS: All consenting adults (n = 455) diagnosed with generalized anxiety or (unipolar) depressive disorders in Suttur village, Karnataka, were treated with open-label fluoxetine (20-60 mg/day), sertraline (50-150 mg/day), escitalopram (10-20 mg/day), desvenlafaxine (50-150 mg/day), duloxetine (30-90 mg/day), amitriptyline (75-150 mg/day), or clomipramine (75-150 mg/day) in a structured, monotherapy dosing plan...

PURPOSE/BACKGROUND: This post hoc analysis examined the time point at which clinically significant improvement in major depressive disorder (MDD) symptoms occurs with desvenlafaxine versus placebo. METHODS: Data were pooled from 9 short-term, double-blind, placebo-controlled studies in adults with MDD randomly assigned to desvenlafaxine 50 mg/d, 100 mg/d, or placebo. A mixed-effects model for repeated-measures analysis of change from baseline score was used to determine the time point at which desvenlafaxine treatment groups separated from placebo on the 17-item Hamilton Rating Scale for Depression and psychosocial outcomes...

Tests based on hyponeophagia phenomena are the most widely used to check the efficacy and efficiency of new-generation chronic antidepressant treatments. Even so, these tests lack strict consensus about their methodology, which reduces their validity, reproducibility and makes translatability difficult. Therefore, after an extensive literature review on this subject, we propose a methodological protocol for the Novelty-Suppressed Feeding Test to normalize this situation. Animals were induced to a reserpine-induced depression model and were then chronically treated with duloxetine, desvenlafaxine or vehicle...

The aim of this study was to quantify the risk of hair loss with different antidepressants. A retrospective cohort study design using a large health claims database in the USA from 2006 to 2014 was utilized. A cohort of new user and mutually exclusive users of fluoxetine, fluvoxamine, sertraline, citalopram, escitalopram, paroxetine, duloxetine, venlafaxine, desvenlafaxine, and bupropion were followed to the first diagnosis of alopecia. The cohort was comprised of 1 025 140 new users of fluoxetine, fluvoxamine, sertraline, citalopram, escitalopram, paroxetine, duloxetine, venlafaxine, desvenlafaxine, and bupropion, with sertraline the most commonly prescribed (N=190 227) and fluvoxamine (N=3010) the least prescribed...

Fatigue and low energy are cardinal symptoms of major depressive disorder (MDD) that have an impact on work functioning. Antidepressants with noradrenergic activity have been hypothesized to improve symptoms of fatigue and low energy. We examined the impact of these symptoms on work functioning in patients with MDD treated with the serotonin and noradrenaline reuptake inhibitor, desvenlafaxine. A secondary analysis was carried out from a study of employed adult outpatients (n=35) with MDD and subjective cognitive complaints treated with desvenlafaxine 50-100 mg/day for 8 weeks...

CLINICAL QUESTION: In menopausal women who experience regular hot flashes, does treatment with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs) reduce the frequency and/or severity of hot flashes? ANSWER: Yes. Review of the literature suggests that treatment with SSRIs or SNRIs reduces the frequency and severity of hot flashes in menopausal and post-menopausal women. Studies demonstrated that paroxetine (Paxil), citalopram (Celexa) and escitolapram (Lexapro) were the most effective SSRIs, and venlafaxine (Effexor) was the most effective first line SNRI, with desvenlafaxine as a second option...

One of the main risks associated with effluents from both wastewater treatment plants (WWTPs) and on-site sewage treatment facilities (OSSFs) is the release of micropollutants (MPs) in receiving water bodies. However, the impact of MPs present in the effluents of OSSFs in the aquatic environment has not been studied so far. The current study evaluates the impact of the effluents of OSSFs and small-to-large scale WWTPs on natural waters. The discharge of 74 MPs was assessed including pharmaceuticals, personal care products, pesticides, artificial sweeteners and perfluoroalkyl substances (PFASs)...

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...
