Opposite effects of opioid blockade on the blood pressure–pain relationship in depressed and non-depressed participants

Abstract: The effect of the opioid antagonist naltrexone on the relationship between blood pressure and pain was examined in 24 participants with major depressive disorder and 31 non-depressed controls, before and after 25 min of stressful mental arithmetic. Pain was induced by immersing the non-dominant foot in 2 degrees C ice-water for as long as possible or until 4 min had elapsed (the cold pressor test). Blood pressure was measured before each cold pressor test, and at 2-min intervals during mental arithmetic. In th… Show more

“…11,31 In contrast, administration of yohimbine increases autonomic activity and symptoms such as restlessness and agitation under low-stress conditions. 51 Blocking α 2 -autoreceptors increases the basal firing rate of neurons in brainstem adrenergic nuclei and boosts the release of adrenergic neurotransmitters from central and peripheral nerve terminals and somato-dendritic sites.…”
