Intranasal oxytocin administration is reflected in human saliva

Abstract

Following the discovery that intranasal administration of neuropeptides can reach the central nervous system, a growing number of studies applied intranasal oxytocin (OT) paradigms to demonstrate the positive effects of OT on social and emotional processes. The three-step paradigm typically included: OT administration, a 45-min waiting period, and approximately 1-h period of active drug effects when experimental manipulations are applied. Yet, this schedule has not been put to systematic validation. Utilizing a double-blind placebo-control within-subject design, ten individuals were administered OT or placebo and salivary OT was measured ten times, at baseline and nine times over four consecutive hours. OT administration induced substantial increases in salivary OT across the entire period. OT rose dramatically 15 min after administration (from 6.9 pg/ml at baseline to 1265.4 pg/ml), reached plateau at 45-120 min (range=131.6 and 105.3 pg/ml), and did not return to baseline by 4h. Results contribute to discussion on brain-periphery coordination of OT and highlight the need for further research on the temporal dynamics and durations of OT administration effects.

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.
