Lactate- and isoproterenol-induced panic attacks in panic disorder patients and controls.
In a double-blind study using sodium lactate and isoproterenol infusions to provoke panic attacks, 73 of 86 panic disorder patients and 10 of 45 controls panicked with lactate, and 58 of 86 patients and 4 of 45 controls panicked with isoproterenol. We measured baseline and peak anxiety ratings in 10 controls with lactate-induced panic attacks, 31 controls who did not panic during lactate infusions, and 63 panic disorder patients who did panic during lactate infusions. The controls who panicked with lactate had robust increases in their anxiety ratings very similar to the increases experienced by patients who panicked with lactate.
