Mechanism of action

Oxytocin is an endogenous nonapeptide hormone and neurotransmitter that acts on oxytocin receptors distributed throughout the central nervous system. When administered intranasally, it crosses the blood-brain barrier and influences neural circuits involved in social behavior, trust, empathy, and stress response. The mechanism is thought to enhance prosocial behaviors and reduce social anxiety through modulation of amygdala and prefrontal cortex activity.
