title: Benzodiazepine receptors modulate circulating plasma vasopressin concentration.
abstract: Chlordiazepoxide pretreatment decreased basal levels of plasma arginine-vasopressin (AVP) and attenuated picrotoxin-induced increases in plasma AVP and blood pressure compared to saline-pretreated spinal animals. Prior administration of RO 15-1788 blocked the effects of chlordiazepoxide on basal plasma AVP as well as picrotoxin-evoked changes in plasma AVP and blood pressure. Thus, interactions at the benzodiazepine receptor may influence basal and evoked changes in plasma AVP concentration.
