title: Effects of laboratory-induced panic-anxiety on subsequent provocative infusions.
abstract: The effects of infusion-induced panic-anxiety on subsequent pre-infusion anxiety ratings and infusion-induced panic attacks were studied in 64 panic disorder patients, in a double-blind randomized study using sodium lactate, isoproterenol, and placebo infusions. While there was a decrease of preinfusion anxiety from one infusion to the next infusion both for panickers and nonpanickers, there was no evidence of either a significant decrease or an increase in the frequency of subsequent panic attacks. These results suggest that there is neither a desensitizing nor a sensitizing effect of pharmacologically induced panic attacks on subsequent infusions in a serial three-infusion design.
