Figure 2. Line graphs showing blood pressure and HPA response to stress, alcohol cue and neutral imagery.

  1. Main effect of Medication Group (PLA >PZ: p=.06)
  2. PZ < PLA following exposure to cue imagery (p=.01)
  3. PZ > PLA following exposure to stress (p=0.1) and cue (p=0.1)
    Note: * Cortisol levels in the neutral condition are decreased compared to baseline due to the expected diurnal drop in plasma cortisol over the course of the laboratory sessions conducted between 8:00 and 10:30 AM in the morning. In the Placebo group, cortisol levels following exposure to stress and cue are decreased reflecting a blunted response. In the Prazosin group, the drop in cortisol is attenuated following exposure to stress (p<.0001) and cue (p<.0001) relative to neutral, indicative of a significant stress and cue-induced increase in cortisol response.
