Replication of action of cholecystokinin tetrapeptide in panic disorder: clinical and behavioral findings
Abstract
Eleven patients with panic disorder were challenged with cholecystokinin tetrapeptide (CCK-4) on two occasions. The effects of CCK-4 were consistent except symptom onset was more rapid with the second injection. Demonstrating that the effects of CCK-4 are reproducible in panic patients opens the doors for studies of the effects of drug treatment on CCK-4-induced panic.
