Description
Oxytocin is a naturally occurring neuropeptide produced in the hypothalamus and released by the posterior pituitary; it plays key roles in uterine contraction, milk ejection, and social bonding.
Usage
Used in research to study parturition (labor induction), lactation, social behavior, and anxiety modulation.
Mechanism of Action
Binds to oxytocin receptors (OXTR) in target tissues, triggering G-protein coupled signaling that leads to uterine smooth muscle contraction, milk let-down, and modulation of central nervous system pathways involved in social cognition.

- Enhancement of social bonding and trust
- Reduction of anxiety in behavioral studies
Side Effects(4)
