VIP
Vasoactive Intestinal Peptide · Aviptadil
A 28-amino-acid neuropeptide of the secretin/glucagon superfamily, widely distributed in the nervous and gastrointestinal systems. It binds the VPAC1 and VPAC2 receptors and is studied for smooth-muscle relaxation, immune modulation, and circadian signaling. The synthetic form is aviptadil.
Half-life
Very short in plasma (~1-2 min); rapidly degraded by peptidases. Half-life is an educational pharmacology figure, drawn from public sources, and is not a schedule or dosing instruction.
Storage & handling
Lyophilized powder kept frozen or refrigerated and protected from light; reconstituted solutions refrigerated and used within a short window, as VIP is degradation-sensitive.
