Oxytocin
Also called Pitocin, Syntocinon
per administration
A human trial worked out how much to take and how often, so a dosing schedule is shown.
Licensed as a medicine in the US and EU.
The human evidence for Oxytocin used the intravenous route. The draw worked out here assumes a subcutaneous injection, so the amount is not a direct read-across.

Published research contexts for Oxytocin describe 20–40 mcg per administration. Descriptive only, not a recommendation.
Only a few minutes in plasma, so any curve here is a brief spike.
A nonapeptide hormone, licensed as a medicine and given by intravenous infusion, intramuscularly, or intranasally in research; amounts are usually stated in international units. No subcutaneous schedule is established, so no schedule table is shown.
Modelled level — every day
1× is the peak after a single dose.
- Steady-state peak
- 0.97× single dose
- Time to steady state
- 1hours
- Administrations
- 7/ week
