Reference entry · Endogenous nonapeptide hormone
Oxytocin
Also known as: OT · Pitocin (approved drug name for labor indication)
- Class
- Endogenous nonapeptide hormone
- Size
- 9 amino acids
- Primary targets (literature)
- Oxytocin receptor (OXTR)
- Regulatory context
- FDA-approved drug products exist for specific obstetric indications (e.g., Pitocin). Catalog oxytocin for laboratory use is not interchangeable with those products without verified identity and regulatory context.
Overview
Oxytocin is among the best-studied neuropeptides in neuroscience and endocrinology, with approved pharmaceutical formulations for defined obstetric indications and a vast experimental literature on social cognition — categories that should not be conflated with catalog RUO material.
Mechanism in research literature
Oxytocin receptor activation modulates uterine smooth muscle, lactation physiology, and central circuits involved in social behavior research — with route-dependent pharmacokinetics that dominate interpretation of human studies.
Common research focus areas
- Social cognition and autism-spectrum research trials
- Intranasal vs. parenteral pharmacokinetics
- OXTR genetics and receptor pharmacology
- Pharmaceutical vs. catalog peptide identity distinction
