Do antidepressants selectively suppress spontaneous (unexpected) panic attacks? A replication.
The purpose of this study was to test the following interrelated hypotheses in a larger sample by attempting to replicate supportive results from a small therapeutic study : ( 1 ) the pathogenesis of panic disorder includes at least two identifiable components : a biological component represented by spontaneous ( unexpected ) panic attacks , and a cognitive component represented by situational attacks and especially by phobias ; ( 2 ) these components respond differently to treatment ; ( 3 ) many biological processes respond to an effective intervention in proportion to their deviance from " normal " prior to treatment ( " Law of Initial Value " ) ; and ( 4 ) the response of spontaneous panic attacks to an effective treatment conforms to that model . Previously , the authors reanalyzed an 8-week therapeutic study of panic disorder that included groups treated with  placebo  and with  imipramine ( 225 mg daily ) . The criteria of response were spontaneous panic attacks ( biological component ) , situational panic attacks ( both components ) , and agoraphobia ratings ( cognitive component ) . The analyses compared the regression lines for posttreatment status on pretreatment status in the imipramine and placebo groups . The effect of imipramine on spontaneous panic attacks fitted the hypothesized model : the pre-post slope in the placebo group was approximately 1 ( 45 degrees ) , whereas the slope in the imipramine group was approximately 0 . There was no significant difference in pre-post slopes between the imipramine and placebo groups for situational panic attacks or agoraphobia ratings . For this report , the authors applied the same approach to another larger data set from a study using a similar design , but a different antidepressant . In this multicenter , double-blind study , patients with panic disorder were r and omly assigned to receive 10 weeks of treatment with  placebo ( N = 78 ) or fluoxetine 10 mg ( N = 84 ) or 20 mg ( N = 81 ) daily . Spontaneous and situational panic attacks were registered in a daily diary , and agoraphobia was rated at each visit . Using baseline and endpoint data , fluoxetine had a statistically significant , dose-dependent , suppressive effect on spontaneous panic attacks , as measured by the pre-post slopes in the three treatment groups . The placebo group showed some response ( slope = 0.69 ) . There were no significant drug effects on situational panic attacks . On ratings of agoraphobia , the slopes in the placebo and the fluoxetine 20 mg groups did not differ , but the slope in the fluoxetine 10 mg group was significantly less than that in the placebo group , suggesting a therapeutic drug effect on agoraphobia only at the lower dose . These results are consistent with the stated hypotheses . They suggest that the therapeutic effects of antidepressants on panic disorder may be due primarily to the specific suppression of spontaneous panic attacks among patients with high baseline pathologic findings . Implication s of these results for concepts of pathogenesis , clinical practice , and therapeutic research regarding panic disorder are discussed
