Mechanism of Action

VIP binds to VPAC1 and VPAC2 receptors, activating cAMP pathways that suppress pro-inflammatory cytokines (TNF-α, IL-6, IL-12) and promote anti-inflammatory mediators. It also acts as a bronchodilator and vasodilator.

Short-Term Effects

Reduced inflammatory symptoms, improved respiratory function, enhanced energy.

Long-Term Effects

Sustained reduction in inflammatory markers and symptom improvement in CIRS.

Side Effects

Generally well-tolerated intranasally. Mild nasal irritation. Hypotension at high doses.

Contraindications

Not recommended without addressing underlying environmental triggers in CIRS.
