Importance: Selective serotonin reuptake inhibitors (SSRIs) may increase the risk for spontaneous intracranial hemorrhage (ICH), an effect that is in theory linked to the strength of inhibition of serotonin reuptake of an antidepressant. However, whether antidepressants that are strong inhibitors of serotonin reuptake actually increase the risk for ICH and the effect of concomitant use of antithrombotics are unknown. Objectives: To assess the risk for ICH associated with the use of SSRIs compared with tricyclic antidepressants (TCAs) among new users of antidepressants and according to the relative affinity of the antidepressant for the serotonin transporter and to assess whether concomitant use of antithrombotics modifies this risk...

We previously demonstrated that a single treatment of a non-peptidic delta opioid receptor agonist, KNT-127, has an antidepressant-like effect in rodents in the forced swim test. Here we evaluated the effect of repeated administration of the potential antidepressant KNT-127 in an olfactory-bulbectomized (OBX) rat model. Male Wistar rats (8-12 weeks old) underwent olfactory bulbectomy. From 14days after surgery each was weighed and administered either KNT-127 (3mgkg(-1)/day), the selective serotonin reuptake inhibitor (SSRI) fluoxetine (10mgkg(-1)/day), or vehicle, daily for 14 days...

BACKGROUND: The intestinal mucosa recovers from injury by accelerating enterocyte proliferation resulting in villus growth. A similar phenomenon is seen after massive bowel resection. Serotonin (5-HT) has been implicated as an important regulator of mucosal homeostasis by promoting growth in the epithelium. The impact of 5-HT on other components of growing villi is not known. We hypothesized that 5-HT-stimulated growth in the intestinal epithelium would be associated with growth in other components of the villus such as enteric neural axonal processes...

Selective serotonin reuptake inhibitors (SSRIs) regulate brain noradrenergic neurotransmission both at somatodendritic and nerve terminal areas. Previous studies have demonstrated that noradrenaline (NA) reuptake inhibitors are able to desensitize α2-adrenoceptor-mediated responses. The present study was undertaken to elucidate the effects of repeated treatment with the SSRI citalopram on the α2-adrenoceptor sensitivity in locus coeruleus (LC) and prefrontal cortex (PFC), by using in vivo microdialysis and electrophysiological techniques, and in vitro stimulation of [(35)S]GTPγS binding autoradiography...

BACKGROUND: Hypothesised associations between in utero exposure to selective serotonin reuptake inhibitors (SSRIs) and congenital anomalies, particularly congenital heart defects (CHD), remain controversial. We investigated the putative teratogenicity of SSRI prescription in the 91 days either side of first day of last menstrual period (LMP). METHODS AND FINDINGS: Three population-based EUROCAT congenital anomaly registries- Norway (2004-2010), Wales (2000-2010) and Funen, Denmark (2000-2010)-were linked to the electronic healthcare databases holding prospectively collected prescription information for all pregnancies in the timeframes available...

 A 70-year-old woman, residing in a nursing home, was admitted to our hospital because of cerebral hemorrhage. She had excessive sweating, a temperature above 37°C, and intermittent muscle spasm such as myoclonus, since the time of admission. We suspected that these symptoms were related to side effects caused by the milnacipran she was taking for depression, prior to hospitalization. After we discontinued milnacipran, the patient began exhibiting withdrawal symptoms such as excitement and insomnia. When we substituted milnacipran with mianserin, the withdrawal symptoms diminished and the excessive sweating and involuntary movement disappeared...

INTRODUCTION: Antidepressants are commonly prescribed during pregnancy; however, there are inconsistent data on the safety of these medications during the prenatal period. To address this gap, this study will investigate short-term and long-term neurodevelopmental, physical and mental health, and educational outcomes of children who have been exposed to selective serotonin reuptake inhibitors (SSRIs) or selective serotonin norepinephrine reuptake inhibitors (SNRIs) and/or maternal depression during pregnancy...

BACKGROUND: Following neuropathy α2-adrenoceptor-mediated diffuse noxious inhibitory controls (DNIC), whereby a noxious conditioning stimulus inhibits the activity of spinal wide dynamic range (WDR) neurons, are abolished, and spinal 5-HT7 receptor densities are increased. Here, we manipulate spinal 5-HT content in spinal nerve ligated (SNL) animals and investigate which 5-HT receptor mediated actions predominate. METHODS: Using in vivo electrophysiology we recorded WDR neuronal responses to von frey filaments applied to the hind paw before, and concurrent to, a noxious ear pinch (the conditioning stimulus) in isoflurane-anaesthetised rats...

INTRODUCTION: Depressive disorder is a common and disabling disorder that causes high rates of morbidity and mortality. Citalopram is an antidepressant drug, of the Selective Serotonin Reuptake Inhibitor (SSRI) class that has been used for geriatric depression since a long time ago. Prescription of omega-3 in geriatric depression has been increased recently; because of more favorable profile of their side effects. Some of the studies reported that omega-3 is effective in prevention or treatment of depressive disorders than Citalopram...

BACKGROUND: Antenatal exposure to selective serotonin reuptake inhibitors (SSRI) is associated with an enhanced risk of preterm birth. Very preterm-born neonates (<32-week gestation) antenatally-exposed to SSRIs may show altered brain development. OBJECTIVE: To examine whether antenatal-SSRI exposure was associated with adverse neonatal brain microstructural and metabolic development using diffusion tensor and magnetic resonance spectroscopic imaging. DESIGN/METHODS: Of 177 neonates enrolled, 14 (8%) were antenatally exposed to SSRIs...

Tramadol is a well-known and effective analgesic. Recently it was shown that tramadol is also effective in human premature ejaculation. The inhibitory effect of tramadol on the ejaculation latency is probably due to its mechanism of action as a μ-opioid receptor agonist and noradrenaline/serotonin (5-HT) reuptake inhibitor. In order to test this speculation, we tested several doses of tramadol in a rat model of male sexual behavior and investigated two types of drugs interfering with the μ-opioid and the 5-HT system...

The effects of fluoxetine, one of the most prescribed selective serotonin-reuptake inhibitors (SSRIs) during pregnancy, and its active metabolite norfluoxetine were studied on placental aromatase (CYP19) and feto-placental steroidogenesis Fluoxetine did not alter estrogen secretion in co-culture of fetal-like adrenocortical (H295R) and trophoblast-like (BeWo) cells used as a model of the feto-placental unit, although it induced CYP19 activity, apparently mediated by the serotonin (5-HT) 2A receptor/PKC signalling pathway...

The purpose of the present study was to investigate the pharmacology of hypidone hydrochloride (YL-0919), a novel selective serotonin reuptake inhibitor (SSRI) and 5-hydroxytryptamine (5-HT)1A receptor agonist with high affinity for serotonin transporter (SERT) and 5-HT1A receptors. YL-0919 promoted [(35) S]GTPγ S binding at 85% of the magnitude of the full 5-HT1A receptor agonist 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT), suggesting that YL-0919 is a high-efficacy partial agonist of 5-HT1A receptors...

We analyzed data from the Japan Environment and Children's Study (JECS), on the association between selective serotonin reuptake inhibitors (SSRI) use during pregnancy and the risk of developing of major congenital anomalies in Japan. JECS is an ongoing nationwide birth cohort study. The study includes 95,994 single pregnant women and their offspring. Among them172 used any SSRI up to the 12(th) gestational week. Crude analyses show a significantly increased incidence of upper limb, abdominal, and urogenital anomalies...

AIM: Use of selective serotonin reuptake inhibitors (SSRIs) in late pregnancy may be associated with an increased risk of persistent pulmonary hypertension of the newborn (PPHN). Limited data are available on the risk of PPHN associated with serotonin norepinephrine reuptake inhibitors (SNRIs). We aimed to quantify both associations. METHODS: Using data from the Quebec Pregnancy Cohort between 1998 and 2009, we included women covered by the provincial drug plan who had a singleton live birth...

Antidepressant treatment reduces behavioural and neural markers of negative emotional bias early in treatment and has been proposed as a mechanism of antidepressant drug action. Here, we provide a critical test of this hypothesis by assessing whether neural markers of early emotional processing changes predict later clinical response in depression. Thirty-five unmedicated patients with major depression took the selective serotonin re-uptake inhibitor (SSRI), escitalopram (10 mg), over 6 weeks, and were classified as responders (22 patients) versus non-responders (13 patients), based on at least a 50% reduction in symptoms by the end of treatment...

Homonymous hemianopsia (HH) is a common adverse outcome after stroke. Spontaneous improvement more than 6 months poststroke is thought to be unlikely, and traditional visual rehabilitation techniques lack clear evidence of efficacy. The case presented is of a 22-year-old woman who demonstrated improved compensation of her stroke-induced HH after the initiation of a selective serotonin reuptake inhibitor (SSRI). There is evidence supporting the use of SSRIs to improve poststroke cognitive impairment, motor impairment, and depression...

Chronic use of selective serotonin re-uptake inhibitors (SSRI) for the treatment of depression has been linked to osteoporosis. In this study, we investigated the effect of chronic SSRI use on fracture healing in two murine models of bone regeneration. First, we performed a comprehensive analysis of endochondral bone healing in a femur fracture model. C57/BL6 mice treated with fluoxetine, the most commonly prescribed SSRI, developed a normal cartilaginous soft-callus at 14 days after fracture and demonstrated a significantly smaller and biomechanically weaker bony hard-callus at 28 days...
