- Intranasal (24–48 IU)
- 30–40 minutes
- 40–60 minutes
- 35–90 minutes
- 90–120 minutes
- Gold standard for CNS delivery; peak prosocial behavior at 40–45 minutes; requires correct nasal administration technique
- Intravenous (2–10 IU bolus)
- 5–10 minutes
- 15–30 minutes
- 20–60 minutes
- 60–90 minutes
- Faster onset but shorter duration; CNS penetration less reliable than intranasal; used primarily in clinical obstetric settings
- Sublingual (12–24 IU)
- 15–25 minutes
- 30–50 minutes
- 30–75 minutes
- 75–100 minutes
- Emerging method with comparable CNS delivery to intranasal; avoids nasal mucosa variability but requires longer hold time (3–5 minutes)
- Chronic intranasal (daily × 4–8 weeks)
- N/A. Steady state
- N/A. Receptor upregulation
- Baseline increase in prosocial behavior
- Persists 2–4 weeks post-cessation
- Produces lasting receptor density changes; effect outlasts individual doses; requires lower daily dose (12–24 IU) to avoid desensitization
