Definition

Oxytocin is a nonapeptide hormone released from the neurohypophysis.1 It differs from vasopressin by two amino acids at residues 3 and 8.

Treatment

Intranasal administration of oxytocin is increasingly explored for its clinical efficacy in autism spectrum disorder.1 A trial involving 79 children, including 16 females, receiving 12 IU of intranasal oxytocin twice daily showed significantly higher salivary oxytocin levels 24 hours after the final administration.1 Additionally, oxytocin is known to transiently prolong the QT/QTc interval.2

Open questions

Despite excitement surrounding the potential therapeutical applications of intranasally administered oxytocin, the results of these intervention studies have been inconsistent.1 While mixed results are often attributed to methodological issues, emerging evidence suggests that the interaction between oxytocin and sex hormones may also account for the varied findings.1

How this page is built

A clinical question appears here only when its condition matches this topic, an outcome and a comparator were extracted from the studies, at least two studies and a patient count are on file, and the certainty is low or higher.

Supports benefit, no benefit shown, and mixed describe the direction of the measured effect. No benefit shown means the evidence does not support a benefit. It is not a finding of harm. Too little evidence means the question did not clear that bar.

Study count, RCT count, and patient count are separate. The patient total adds only studies that are linked into a study family and whose sample size is not flagged as implausible. A reversal is listed only when at least one randomized trial sits on each side of the change.

The overview is drafted from the guideline recommendations, trials, papers, and questions on this page, and every sentence has to cite one of them. It stays unverified until an NPI-verified clinician or a Synapse admin approves it. Approving records that person's name.
