Status Recruiting

Clinical Trial Summary

Two hundreds and ten women with premenstrual syndrome will be randomly divided into 3 equal groups using computer generated random numbers. Group 1 will receive oral dienogest (visanne® Bayer, Germany) 2mg for 14 days starting from the 15th day of menstruation, Group 2 will receive fluoxetine (Prozac® Lilly, UK) 20mg and group 3 will receive an oral placebo foe 14 days starting from the 15th day of menstruation.

Clinical Trial Description

Premenstrual syndrome (PMS) manifests with distressing physical, behavioral and psychological symptoms, in the absence of organic or underlying psychiatric disease, which regularly recur during luteal phase of each menstrual cycle and disappear or significantly improve by the end of menstruation. Approximately 85-90 % of women may experience premenstrual emotional and physical changes in their reproductive age and the prevalence of severe PMS ranges from 3% to 8%. The etiology of PMS is unknown but cyclical ovarian activity and the effect of estradiol and progesterone on serotonin and gamma-amino butyric acid are key factors. Absence of PMS before puberty, in pregnancy and after the menopause supports a role of cyclical ovarian activity in PMS etiology. PMS symptoms include psychological symptoms like mood swings, irritability, depression and feeling out of control; physical symptoms like breast tenderness, bloating and headaches; and behavioral symptoms like reduced visuospatial and cognitive ability. To diagnose PMS, symptoms should be recorded prospectively over two cycles using a symptom diary. Several symptom diaries exist but the Daily Record of Severity of Problems (DRSP) is reliable and simple for patients. There is increasing evidence that serotonin may be important in the pathogenesis of PMS. A number of selective serotonin reuptake inhibitors have been used to treat PMS. Fluoxetine at was found to significantly reduce symptoms of tension, irritability and dysphoria, as well as physical symptoms compared with placebo, as measured by visual analogue scales. Luteal phase sertraline was found effective in the management of severe PMS. Historically, treatment with progesterone was based on the hypothesis that in PMS sufferers, the ratio of progesterone and its derivatives to other hormones was lower than is usual in women. This allowed oestrogens to cause water retention, because there was insufficient progesterone to oppose them. Gama amino butyric acid (GABA) produced by inhibitory neurons calms symptoms of anxiety, irritability and aggression. Part of the receptors, called GABA(A) on the neurone surface, necessary for GABA to have its effect, cannot be made without the break-down products of progesterone. The occurrence of severe symptoms has been correlated with falling levels of progesterone metabolites. Therefore, progesterone could relieve the symptoms of PMS by preventing falling levels of progesterone metabolites and loss of GABA(A) enhancement. PMS will be diagnosed prospectively using the DRSP. DRSP is a questionnaire comprised of 25 physical and emotional symptoms including impairment of physical and social activities, women will be asked to give a score of 1 to 6 for each symptom 1 = not at all, 2 = minimal, 3 = mild, 4 = moderate, 5 = severe, 6 = extreme. The investigators will add the symptoms scores of the first day of menses and PMS will be excluded if the score was < 50. If the total score is greater than 50, the patients will record two cycles of symptoms. If more than three items have an average score of more than 3 (mild) during the luteal phase, the investigators will add the scores of five-day intervals during the luteal and follicular phases. PMS will be diagnosed when the luteal phase score is 30 percent greater than the follicular phase score in the 2 months. Women with PMS will be asked to take the drugs for 3 months and keep recording their symptoms and symptom scores will compared to those documented before treatment. Two hundreds and ten women with premenstrual syndrome will be randomly divided into 3 equal groups using computer generated random numbers. Group 1 will receive oral dienogest (visanne® Bayer, Germany) 2mg for 14 days starting from the 15th day of menstruation, Group 2 will receive fluoxetine (Prozac® Lilly, UK) 20mg and group 3 will receive an oral placebo foe 14 days starting from the 15th day of menstruation. ;
