  • Oxytocin Carbetocin
    CARBETOCIN To prevent life-threatening pregnanCy CompliCations Postpartum haemorrhage (PPH) is commonly defined as a blood loss of at least 500 ml within 24 hours after birth, and affects about 5% of all women giving birth around the world. Globally, nearly one quarter of all maternal deaths are associated with PPH, and in most low-income countries it is the main cause of maternal mortality. The use of good quality prophylactic uterotonics can avoid the majority of PPH-associated complications during the third stage of labor (the time between the birth of the baby and complete expulsion of the placenta). In settings where oxytocin is unavailable or its quality cannot be guaranteed, the use of other injectable uterotonics (carbetocin, or if appropriate ergometrine/methylergometrine, or oxytocin and ergometrine fixed-dose combination) or oral misoprostol is recommended for the prevention of PPH. The use of carbetocin (100 μg, IM/IV) is recommended for the prevention of PPH for all births in contexts where its cost is comparable to other effective uterotonics. Carbetocin is only recommended for the prevention of postpartum hemorrhage and not recommended for other obstetric indications, such as labor induction, labor augmentation or treatment of PPH.

  • The Oxytocin Receptor Gene (OXTR) Is Associated with Autism Spectrum Disorder: a Meta-Analysis
    Molecular Psychiatry (2015) 20, 640–646 © 2015 Macmillan Publishers Limited All rights reserved 1359-4184/15 www.nature.com/mp ORIGINAL ARTICLE The oxytocin receptor gene (OXTR) is associated with autism spectrum disorder: a meta-analysis D LoParo and ID Waldman The oxytocin receptor gene (OXTR) has been studied as a risk factor for autism spectrum disorder (ASD) owing to converging evidence from multiple levels of analysis that oxytocin (OXT) has an important role in the regulation of affiliative behavior and social bonding in both nonhuman mammals and humans. Inconsistency in the effect sizes of the OXTR variants included in association studies render it unclear whether OXTR is truly associated with ASD, and, if so, which OXTR single-nucleotide polymorphisms (SNPs) are associated. Thus, a meta-analytic review of extant studies is needed to determine whether OXTR shows association with ASD, and to elucidate which specific SNPs have a significant effect on ASD. The current meta-analysis of 16 OXTR SNPs included 3941 individuals with ASD from 11 independent samples, although analyses of each individual SNP included a subset of this total. We found significant associations between ASD and the SNPs rs7632287, rs237887, rs2268491 and rs2254298. OXTR was also significantly associated with ASD in a gene-based test. The current meta-analysis is the largest and most comprehensive investigation of the association of OXTR with ASD and the findings suggest directions for future studies of the etiology of ASD.

  • A Role for Oxytocin in the Acute Reinforcing Effects and Long-Term Adverse Consequences of Drug Use?
    British Journal of Pharmacology (2008) 154, 358–368 & 2008 Nature Publishing Group All rights reserved 0007– 1188/08 $30.00 www.brjpharmacol.org REVIEW From ultrasocial to antisocial: a role for oxytocin in the acute reinforcing effects and long-term adverse consequences of drug use? IS McGregor1, PD Callaghan1 and GE Hunt2 1School of Psychology, University of Sydney, Sydney, Australia and 2Department of Psychological Medicine, University of Sydney, Sydney, Australia Addictive drugs can profoundly affect social behaviour both acutely and in the long-term. Effects range from the artificial sociability imbued by various intoxicating agents to the depressed and socially withdrawn state frequently observed in chronic drug users. Understanding such effects is of great potential significance in addiction neurobiology. In this review we focus on the ‘social neuropeptide’ oxytocin and its possible role in acute and long-term effects of commonly used drugs. Oxytocin regulates social affiliation and social recognition in many species and modulates anxiety, mood and aggression. Recent evidence suggests that popular party drugs such as MDMA and gamma-hydroxybutyrate (GHB) may preferentially activate brain oxytocin systems to produce their characteristic prosocial and prosexual effects. Oxytocin interacts with the mesolimbic dopamine system to facilitate sexual and social behaviour, and this oxytocin-dopamine interaction may also influence the acquisition and expression of drug-seeking behaviour. An increasing body of evidence from animal models suggests that even brief exposure to drugs such as MDMA, cannabinoids, methamphetamine and phencyclidine can cause long lasting deficits in social behaviour. We discuss preliminary evidence that these adverse effects may reflect long-term neuroadaptations in brain oxytocin systems.

  • Repeated Oxytocin Prevents Central Sensitization by Regulating Synaptic
    Wang et al. The Journal of Headache and Pain (2021) 22:84 The Journal of Headache https://doi.org/10.1186/s10194-021-01299-3 and Pain RESEARCH ARTICLE Open Access Repeated oxytocin prevents central sensitization by regulating synaptic plasticity via oxytocin receptor in a chronic migraine mouse model Yunfeng Wang1,2†, Qi Pan1†, Ruimin Tian1, Qianwen Wen3, Guangcheng Qin3, Dunke Zhang3, Lixue Chen3, Yixin Zhang1* and Jiying Zhou1* Abstract Background: Central sensitization is one of the characters of chronic migraine (CM). Aberrant synaptic plasticity can induce central sensitization. Oxytocin (OT), which is a hypothalamic hormone, plays an important antinociceptive role. However, the antinociceptive effect of OT and the underlying mechanism in CM remains unclear. Therefore, we explored the effect of OT on central sensitization in CM and its implying mechanism, focusing on synaptic plasticity. Methods: A CM mouse model was established by repeated intraperitoneal injection of nitroglycerin (NTG). Von Frey filaments and radiant heat were used to measure the nociceptive threshold. Repeated intranasal OT and intraperitoneal L368,899, an oxytocin receptor (OTR) antagonist, were administered to investigate the effect of OT and the role of OTR. The expression of calcitonin gene-related peptide (CGRP) and c-fos were measured to assess central sensitization. N-methyl D-aspartate receptor subtype 2B (NR2B)-regulated synaptic-associated proteins and synaptic plasticity were explored by western blot (WB), transmission electron microscope (TEM), and Golgi-Cox staining. Results: Our results showed that the OTR expression in the trigeminal nucleus caudalis (TNC) of CM mouse was significantly increased, and OTR was colocalized with the postsynaptic density protein 95 (PSD-95) in neurons.
