Study population: Panic disorder patients 20 years of age or older to visit the Samsung Seoul Hospital, and the Department of Mental Health, a foreign patients, patients who agreed to participate in this study will be of. Plan the patient-specific total of 100 patients on each drug treatment group and combined treatment group, 55 patients recruited by the first year of study commences 1 years F / U to enforce the number of subjects.

Brief summary: It is known that the treatment of panic disorder with medication and psychotherapy are both effective. Representative as a treatment for panic disorder, Selective serotonin reuptake inhibitors (SSRIs) are recommended as first-line treatment of panic disorder. In general, the initial reaction rate of panic disorder medication known to be frequently stopped early recurrence 70-80% It's too early, it is recommended that the duration of drug treatment for at least one year to be long-lasting. But whether it is appropriate for the duration of drug treatment to maintain a certain extent remains controversial, and maintain the medication for more than one year, even if the long-term effects known to be approximately 50% less than beyond being negative when remission based. Meanwhile, the typical method for the treatment of panic disorder psychology, cognitive behavioral therapy (Cognitive behavioral therapy) and looked comparable to the effect of the drug in the treatment of the known, especially in recent years when the combined treatment with medication can increase the long-term treatment of sexual reported that there's has been the subject of attention.

But prospectively compare the long-term effects of these two treatments, research, especially the research about the long-term effects of the combined treatment with the drug treatment of panic disorder is very low, and almost nil is Researchers, drug treatment and the effect of the combined treatment in patients with panic disorder over two years prospective study to compare the plans were. And verification, the researchers performed only through this study by comparing the long-term effects of the combined treatment with medication combined treatment of medication to be more effective than if the reaction to the long-term treatment of panic disorder that can affect the clinical and biological factors navigate to evaluate them. In addition, long-term observational study, panic disorder patients' subjective quality of life actually improved to some extent on the map together proven to.

Detailed description: Panic disorder SSRI medication and long-term effects of the combined treatment on the Hamilton Rating Scale more effective treatment compared with the Scale for Anxiety (HAM-A), Clinical Psychology, I try to find the law. Drug and combination therapy of panic disorder from affecting the long-term effects on clinical (demographic and economic Factors), and to check for navigation and biological factors. - Improved quality of life to some extent due to the long-term treatment of patients with panic disorder, if you want to check

2.3 Expected Effects Panic disorder in a comparative study of the long-term effects of the combined treatment with SSRI medication until now very rare, and most of the research to target Westerners, Asians to study is almost wholly lacking. Also to investigate the nature of the clinical course of panic disorder, long-term study also little or no sleep. Elapsed for the treatment of long-term treatment of panic disorder and its impact on various clinical variables to be able to figure out if, through the analysis of the results of this study, the future could be a very useful background material, used in the development of clinical care guidelines is expected. Leading researchers in various studies for panic disorder at home and abroad, and also, therefore, the results obtained in this research is very useful in the pathogenesis and in the treatment of panic disorder is expected. The results of this study will be introduced in the Domestic Society and International Society, will finally be published in major journals of SCI related.

3 Research plan 3.1 Research information and how to

- The selection of subjects Diagnosis by the DSM-IV diagnostic criteria for major panic attacks in patients with disabilities will be conducted by a clinical psychologist or psychiatrist: Mini International Neuropsychiatric Interview Plus (MINI-plus) of structured skilled diagnostic tool.

In the case of patients who were taking medication Airlines sulfur existing at least 2 weeks (hydrochloric acid flu Jade Satin scheduled to participate in a study of the existing 4 weeks) and stop taking the drug. All other prescription non-drug (herbal medicine), forbids smoking within 24 hours before the test, caffeine drink, drinking is prohibited in the state to proceed with a test is scheduled.

Treatment conditions Randomization Randomization table belonging goes: medication alone group and the combined treatment group on either side Will be determined by the SSRIs Tx group -\> Korean panic disorder treatment algorithm (Korean Medication Algorithm for Panic Disorder 2008: Initial Treatment Strategies. J. C. Yang et al., 2008) according to the treatment by applying Standardized treatment is expected to be performed. Single use only, benzodiazepine (alprazolam) and tapering zolpidem use, but only occasionally, within 3 months of treatment, so that Should, in principle, (using the PRN as alprazolam available).

* Combined Tx group SSRIs Tx group, and the same drug treatment to be carried out once a week underwent 10 sessions of CBT, and, after 3 Once a month booster session is scheduled to be performed.

  - Therapists
* Treatment conducted by a psychiatrist skilled in both groups, but CBT case of a qualified clinical psychology Scholars will participate as an adjunct therapy in the treatment session.

  * Assessment Is scheduled to visit (24 months) to assess the clinical manifestations: a total of 11 times.

Visit 1: Screening \& Baseline Visit 2,3,4: every visit per month. / CBT once a week about 3 months, 10 sessions of treatment Visit 5-11: every 3 months to visit / CBT Booster session in three months, once implemented

    * Statistical analyses Methods of treatment: comparison between the two treatment groups for baseline anxiety severity, and status as a covariate Will be analyzed under analysis of covariance (ANCOVA) model using For comparison: two treatments according to the degree of improvement between the groups (remitters) the Cochran- It is planned to use the Mantel-Haenszel test. Personality or reaction and make a difference, according to the genetic factor gene to gene on gene interaction, and gene to environment interaction multiple regression or MDR (multidimensional reduction) using the statistical program is expected to be analyzed.
