Recent animal studies have shown that pretreatment with centrally active cholecystokinin (CCK) antagonists blocks the anxiogenic effects of CCK-tetrapeptide (CCK-4). In order to determine whether pretreatment with these antagonists can block the anxiogenic effects of CCK-4 in patients with panic disorder, a suitable challenge dose of CCK-4 must be selected. Thus, we conducted a dose range study in which patients with panic disorder (n = 29) were challenged with CCK-4 (10, 15, 20, or 25 micrograms) or placebo on two separate occasions, in a balanced incomplete block design. Patients received in random order 10 micrograms (n = 12), 15 micrograms (n = 11), 20 micrograms (n = 12), or 25 micrograms (n = 12) of CCK-4 or placebo (n = 11). CCK-4 induced anxiety and panic responses in a dose-dependent fashion. The incidence of panic attacks following the CCK-4 challenge was 17% (10 micrograms), 64% (15 micrograms), 75% (20 micrograms), and 75% (25 micrograms). None of the patients panicked with placebo. Moreover, a strong linear relationship between CCK-4 and increases in heart rate and diastolic blood pressure was found. The findings of this study suggest that a dose of 20 micrograms of CCK-4 (ED75) might be suitable for efficacy studies of CCKB antagonists and other potential antipanic drugs in patients with panic disorder.
