Oxytocin and Pain: A Systematic Review and Synthesis of Findings

Rash, Joshua A., Aguirre-Camacho, Aldo, Campbell, Tavis S.·2014·The Clinical Journal of Pain

Abstract

OBJECTIVES: A review of the literature was conducted to assess the association between oxytocin (OT) and pain. METHODS: PsychInfo, PubMed, and Medline (EBSCO) research databases were searched for peer-reviewed articles written between 1950 and 2012. Of a total of 1166 articles returned, 50 (9 human, 33 animal, and 8 spinal cord samples) met full inclusion criteria and were included in the review. RESULTS: OT had a reliable effect as defined by increasing pain tolerance in 29 of 33 animal studies reviewed. This effect persisted across central and peripheral modes of administration and type of noxious stimulus used (eg, heat, electric). The results suggest that OT acts as an analgesic for acute pain in animals. Preliminary research with humans offers consistent evidence to suggest that OT decreases pain sensitivity, though the reliability and stability of such effects cannot yet be determined. Although the findings are encouraging, there is a need for methodologically rigorous work in humans where OT is administered centrally. DISCUSSION: Further research seems to be warranted as the existence of biologically and psychologically plausible mechanisms linking OT and pain have been well supported using animal models with limited but encouraging human research. Implications and recommendations are discussed. Findings from this research may inform therapeutic methods for the management of pain.

  • The stronger reduction of anterior insula activity to electric shocks under partner support after intranasal oxytocin may reflect anti-nociceptive effects of oxytocin.

    “Mechanistically, the stronger reduction of AI activity to electric shocks under partner support after the administration of intranasal OXT may reflect anti-nociceptive effects of OXT that have been recently reported in human and animal studies (Rash, Aguirre-Camacho, & Campbell, 2014).”

  • Oxytocin can act as a painkiller.

    “These results are interesting in light of work showing that oxytocin can not only act as an anxiolytic,51, 52 but can also act as a painkiller.53”
  • Robust preclinical evidence has demonstrated that exogenous oxytocin has antinociceptive effects and has identified plausible underpinning mechanisms.

    “Robust preclinical evidence has demonstrated that exogenous oxytocin has antinociceptive effects and has identified plausible underpinning mechanisms 6.”
  • Oxytocin attenuated both neural and psychophysiological responses to the aversive electric shock.

    “Furthermore, in accordance with previous findings (Rash et al, 2014), OXT attenuated both neural and psychophysiological responses to the aversive electric shock.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
