Overview

A synthetic analog of vasopressin with enhanced V2 receptor selectivity and minimal V1a vasopressor activity. Desmopressin has a deaminated cysteine at position 1 and D-arginine at position 8, increasing its antidiuretic potency 10-fold while largely eliminating the hypertensive effects of native vasopressin.
