VIP, a 28-amino acid peptide belonging to the secretin-glucagon-CRF
family, is widely distributed in the central and peripheral nervous systems.
Acting both as a neurotransmitter and as a hormone, VIP is involved in a wide

this peptide in combination with the adrenergic drug phentolamine is expected to
provide a new and effective alternative for erectile dysfunction
