There have been a large number of studies conducted investigating the use of selective serotonin reuptake inhibitors (SSRIs) in the treatment of patients with premenstrual dysphoric disorder (PMDD). The 12 randomised, controlled trials with continuous dose administration of SSRIs and the eight randomised, controlled trials with luteal phase dose administration (from ovulation to menses) are reviewed. All the treatment studies on fluoxetine, sertraline, paroxetine and citalopram have reported positive efficacy. Fluoxetine and sertraline have the largest literature, with a smaller number of studies endorsing paroxetine and citalopram. Mixed efficacy results have been reported with fluvoxamine. In general, adverse effects from the use of SSRIs in women with PMDD are the usual mild and transient adverse effects from SSRIs including anxiety, dizziness, insomnia, sedation, nausea and headache. Sexual dysfunction and weight gain can be problematic long-term adverse effects of SSRIs, but these effects have not been systematically evaluated with long-term SSRI use in women with PMDD. Serotonergic antidepressants have differential superiority over nonserotonergic antidepressants in the treatment of PMDD. Treatments that enhance serotonergic action improve premenstrual irritability and dysphoria with a rapid onset of action, suggesting a different mechanism of action than in the treatment of depression. It is possible that neurosteroids, such as progesterone metabolites, are involved in the rapid action of serotonergic antidepressants in PMDD. Future research needs to address less frequent dose administration regimens, such as 'symptom-onset' dose administration, and the recommended length of treatment.

Objective To observe the changes of Chinese medicine (CM) symptoms, the distri- bution characteristics of CM syndromes, and related neuroendocrine levels in premenstrual dysphoric disorder (PMDD) patients. Methods Totally 3 541 female outpatients (18 -45 years old) were inter- viewed by clinical epidemiological questionnaire. According to PMDD diagnostic criteria in DSM-IV , PMDD patients' CM syndromes were identified. Their scores of main symptoms and CM symptoms of common CM syndromes were compared. Contents of 8 neuroendocrine indicators in serum were detected [5- hydroxytryptamine (5-HT) , adrenocorticotropic hormore (ACTH) , angiotensin-II (Ang-II ) , glucocorti- coid (GC), homocysteine (Hcy), melatonin (MLT), nitrogen monoxide (NO), neuropeptide Y (NPY)]. Results Totally 258 PMDD were detected in 3 541 female outpatients (18 -45 years old). The main syn- drome and common syndromes of PMDD patients were reversed invasion of Gan qi syndrome [40.3% (104/258)] and stagnation of Gan qi syndrome [34. 9% (90/258) ], followed by Gan stagnation Pi deficiency syndrome [7.8%(20/258)], Gan stagnation blood stasis syndrome [7.4% (19/258)], Gan stagnation induced fire hyperactivity syndrome [ 6.2% ( 16258 )], Gan stagnation Shen deficiency syndrome [3.1%(8/258)], and Pi-Shen yang deficiency syndrome [0.4%(1258)]. Compared with reversed invasion of Gan qi syndrome, emotional depression and low spirits were main symptoms of stagnation of Gan qi syndrome. Scores for the two symptoms increased (P <0.05). Compared with stagnation of Gan qi syn- drome, irritability, upset, abdominal distension, anxiety, headache, dizziness, insomnia, head distension, bitter mouth, unclear vision were main symptoms of reversed invasion of Gan qi syndrome. Scores for the 10 symptoms increased (P <0.05). Compared with stagnation of Gan qi syndrome, the Hcy level in serum obviously decreased in reversed invasion of Gan qi syndrome (P <0.05). There was no statistical difference in the rest indices (P >0. 05). Conclusions PMDD is closely related to Gan failing to maintain normal flow of qi. Reversed invasion of Gan qi syndrome and stagnation of Gan qi syndrome have different scientif- ic connotations and biological bases. So regulating Gan should be considered as the first choice.
