Blood samples were collected with an indwelling intravenous catheter at 30-min intervals from 0930h to 1530h and prolactin determined by radioimmunoassay. In both groups, fenfluramine induced a rise in the plasma prolactin concentration from baseline. The patients showed a greater increase in prolactin response than the normal controls. This result is consistent with the hypothesis of increased serotonin receptor function in patients with panic di..
