VIP
Vasoactive Intestinal Peptide
Evidence & Status
- Preliminary / Experimental
- Preliminary
At a Glance
A naturally occurring 28-amino-acid neuropeptide. The current record is limited to route-specific human IV pharmacology, inhaled pulmonary-hypertension research, and aviptadil trial-status context; it does not establish broad therapeutic benefit.
Plain English
Researchers study VIP because it is a naturally produced signaling molecule with vascular and immune-system roles. The current human evidence in this record is limited to specific IV and inhaled research settings. Aviptadil is a synthetic VIP formulation with registered COVID-19 trials, but registry entries do not demonstrate clinical efficacy.
Overview
VIP is a naturally occurring 28-amino-acid neuropeptide; aviptadil is a synthetic VIP formulation. The verified record includes review context, human IV pharmacology, and inhaled VIP pulmonary-hypertension research. Aviptadil trial registries provide study-status context only. Evidence is route- and entity-specific and does not establish broad therapeutic efficacy or FDA approval.
Research Summary
VIP/aviptadil remains preliminary. Human evidence is limited and route-specific: IV VIP pharmacology and inhaled pulmonary-hypertension research. Aviptadil COVID-19 registry records establish study status only, not efficacy. No FDA-approved indication or general therapeutic dosing exists.
Research Areas
- Human IV VIP pharmacology
- Inhaled VIP pulmonary-hypertension research
