In recent years, new anti-depressants of SNRI or SSRI and so on became clinical and available in Japan and the width of the choice spread. However, there is little effective report to the chronic pain in Japan to SSRI that an adaptation disease does not have an effect. 　We report because it verified the effectivity of Escitalopram of SSRI for the glossodynia which is accompanied by an anxiety disorder or depressive state.  Moreover, the production of effect is added considering about the permitted action mechanism from the early stage.Ⅱ　Methods　From 2013 in 3 years and half-year of the pasts, we treated with Escitalopram of SSRI for 45 female and 5 male of the glossodynia which complained of the non-organic-pain.  The evaluation used Visual Analogue Scale (VAS). 　It evaluated the effectivity of Escitalopram on retrospective study.　It used corresponding t - test ( improvement rate ) and  χ2 - test ( the comparison among the groups ) which is compatible with the significant test for it and it judged that there was a significant difference about p<0.05.Ⅲ　Results　The patients who could not continue a treatment until 2 week after was 10 examples on not coming to hospital: 5 cases, nausea 3 and vertigo 2 cases.　Patient characteristics: About 90 percent of women, it is 30 % of depressed states, 65 % of anxiety disorder. There were many 70 percent and old patients in above the sixty something within an average of 65.7 years old.　VAS score  was improved  from the early stage; start of therapy 6.45±1.97, after 1 week administration of Escitalopram 5.6±2.32 (p=0.008)、 after 2 week administration of 12 高山赤十字病院紀要（第41号）Escitalopram 2.65±2.(57 (p=2.1×10-12)　Remission rate (VAS=0) of the glossodynia was increased from the early stage on 1W: 5%, 2W: 42.5%, 4W: 75%.Ⅳ　Discussion　Escitalopram (5 to 20 mg activity) of SSRI had an effect on the patients of glossodynia with anxiety disorder or depressive state.  About half patients were disappeared from glossodynia within 2 weeks early and 75% of patients were disappeared from glossodynia within 4 weeks1). Escitalopram of SSRI may be useful for chronic pain of the head and neck area such as the glossodinia symptom and the atypical-facial-pain. It was effective for the cases that SNRI was ineffective2). It is said that there is a pain reduction which is equal to duloxetine 60 mg in escitalopram 20 mg to the chronic lumbago3). Otto and others4) are reporting that the pain reduces by the double-blind which prescribed escitalopram 20 mg a day for the cases of the painful neuropathy.　The chronic pain disappearance operation by antidepressant (escitalopram) which was reported in this time seems to be earlier than the manifestation of the antidepressant effect which is said to be equal to or more than 2 ～ 4 weeks generally.　Therefore, We added considering below about the possibility of the mechanism that Esc i ta lopram of  SSRI shows immediate effectivity in the glossodynia that is a non-organic chronic pain.Fig　1: The figure of left end is health status, the figure of center is chronic pain condition and the figure of right end is the mechanism of the chronic pain restraint behind the escitalopram of SSRI internal use.13The Supposition of the Mechanism of SSRI to the glossodynia as Non-Organic-Pain (in the Mouth and Face Area)Ⅴ　 Conclusions　Escitaloplam which is SSRI was prescribed to 40 patients of the glossodynia. The pain disappearance from the early stage seemed to be earlier than the operation manifestation time of antidepressant which is explained in the 5-HT1A receptor down regulation. Therefore, it logically estimated the different chronic pain restraint mechanism which acts only in 5-HT. It pointed out the possibility that the phasic dopamine increase by 5-HT system antidepressant from the ventral tegmental area and the β-endorphin increase from the corpus striatum and the globus pallidus which is caused by this anticipate in the manifestation of the very early chronic pain improvement effect of escitalopram which is seen by the chronic  pain patients5)(Fig 1).Ⅵ　 References１）Tsunemasa OHKUBO, Toshihiro ANDO et. al : The Early Effect Onset of SSRI to the Non-Organic-Pain in the Mouth and Face Area, JRC Takayama Hosp (in press)２ ） K e n s y u  S H I R A K A W A ,  S h i n s u k e HAMAGUCHI et. al : Clinical evaluation of efficacy of escitaroplam for treatment of chronic pain, Pain Clinic 34: 1127-1131. 2013３）Mazza M., Mazza O et. al : Escitalopram 20 mg versus duloxetine 60 mg for the treatment of chronic low back pain, Expert Opin Pharmacother 11: 1049-1052. 2010４）Otto M, Bach FW et. al : Escitalopram in painful polyneuropathy: A randomized, placebo-controlled, cross-over trial.
