Other Names: AVP
Vasopressin’s most important role is the to regulate water retention by the body. It promotes reabsorption of water in the kidneys, thus concentrating the urine. In larger concentrations, it causes moderate vasoconstriction and increased blood pressure. Recently, increased plasma levels of AVP were associated positively with anxiogenic effects in men, but not women. Young, L.J.; Front. Neuroendocrinol., 30, 425, (2009); Brown L.A. and Chen M., Am.
