01Mechanism of Action

Parameter

DSIP

Oxytocin

Primary target

Multiple — modulates HPA axis + thalamic delta-wave generation (proposed)Schneider 1986

Oxytocin receptors (OXTR) — hypothalamus, amygdala, hippocampus, ventral tegmental area

Pathway

Reduced cortisol/ACTH + enhanced delta-wave EEG activity → improved sleep onset + depthSchneider 1986

OXTR activation → Gq/11-coupled signaling → modulation of GABAergic, dopaminergic, serotonergic pathways → enhanced synaptic plasticity, neurogenesis, emotional regulation

Downstream effect

Faster sleep onset, increased delta sleep, reduced stress response, possible anxiolytic effectSchneider 1986

Social bonding enhancement, trust behavior, gaze modulation, reciprocal eye contact, anti-inflammatory and antioxidant neuroprotection, reduced amygdala threat responsePaul 2026 Prinsen 2026 Yuan 2026

Feedback intact?

—

Yes — endogenous oxytocin-mediated feedback via central and peripheral OXTR pathways

Origin

Endogenous peptide first isolated from rabbit blood during delta sleep; synthesised exogenouslySchneider 1986

Endogenous 9-amino-acid peptide synthesized in hypothalamic paraventricular and supraoptic nuclei, released from posterior pituitaryPaul 2026

05Administration Protocol

Parameter

DSIP

Oxytocin

1. Reconstitution

Add 1–2 mL bacteriostatic water to vial.

Administer 24–48 IU (typically 3–6 puffs per nostril) using nasal spray device. Patient should be seated, head tilted slightly forward. Avoid sniffing deeply; allow passive absorption.

2. Injection site

SQ — abdomen. Rotate sites.

Administer 30–90 minutes before anticipated social interaction or cognitive assessment. Acute effects peak within 30–60 minutes.

3. Timing

30–60 min pre-sleep.

Dilute oxytocin 10 units in 1000 mL isotonic saline. Initiate at 0.5–2 mU/min via infusion pump. Titrate every 30–60 minutes based on contraction pattern and fetal heart rate. Continuous electronic fetal monitoring required.

4. Storage

Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.

Store at 2–8 °C (refrigerated). Do not freeze. Protect from light. Discard if solution is discolored or contains precipitate.

5. Needle

29–31G insulin syringe.

Chronic administration protocols (4–12 weeks) documented in pediatric ASD populations. Daily or twice-daily intranasal administration. Safety profile in chronic use still under investigation.
