CRF1 receptor antagonist CP-154,526 reduces cardiovascular responses during acute psychological stress in rabbits.

Abstract:

:We examined the effect of CP-154,526 on cardiovascular changes elicited in conscious rabbits by stressful stimuli (loud sound, cage move, pinprick, formaldehyde vapour and air-jet stress). CP-154,526 substantially reduced pressor and heart rate responses to these stimuli (both vagally and sympathetically mediated), and reduced QT shortening during air-jet stress. Blocking of central CRF1 receptors attenuates cardiovascular responses to environmental stimuli, presumably by affecting brain centres that control cardiovascular functions.
