  3. Subjects who are taking benzodiazepines, SSRIs, or medication that is effective for the prevention or treatment of the patient's panic disorder (i.e., no patient will be withdrawn for medication that is working for the purpose of entry into this study) must be excluded.
  4. Subjects who are clinically depressed must be excluded.
  5. Subjects who have received an investigational drug within 30 days (or within 5 half lives of the investigational drug) prior to test day must be excluded.
  6. Subjects with epilepsy or other convulsive disorders must be excluded.
  7. Subjects with a history of allergy or intolerance to benzodiazepines or related drugs (alprazolam, lorazepam, diazepam, etizolam, clonazepam, adinazolam) must be excluded.
