Arginine vasopressin (AVP) enhances reflex buffering of its own pressor response, thus attenuating its vasoconstrictor potential in vivo. To investigate the extent to which this effect of AVP is mediated by V1 or V2 receptors, mean arterial pressure (MAP) and heart rate (HR) changes were examined in response to graded injections of AVP or [Phe2,Orn8]oxytocin, a potent, selective V1-receptor agonist, in the absence and presence of infusion of [Val4,D-Arg8]VP, a selective V2-receptor agonist… CONTINUE READING
