2014-08-27 03:19:49 | BioPortfolio


The purpose of this study is to compare the efficacy of calcium carbonate to fluoxetine in the treatment of moderate to severe PMS. Second, to compare each active agent to a placebo control. Third, to evaluate the efficacy of each treatment for specific symptom clusters (i.e. affective and somatic). Fourth, to determine whether the addition of calcium to on going fluoxetine treatment leads to additional therapeutic benefit.


This is a double blind, randomized, placebo controlled, parallel study that will randomize 60 women at the Yale site into treatment. Participants will be screened at various collaborating ob-gyn centers for possible PMS symptoms, and direct referrals from the community will also be accepted. Subject participation length is about 7 months with 6 scheduled study visits.

Methodology: After successfully completing the screening and qualification phase, participants will be randomized to treatment at Visit 1 for 5 cycles of double-blind treatment. Participants will be evaluated monthly during the randomization phase for adverse events, concurrent medication, and primary and secondary efficacy variables.

Premenstrual dysphoric disorder (PMDD) may involve a wide range of physical or emotional symptoms, which are more severe and debilitating than those seen with premenstrual syndrome (PMS), and which include at least one mood-related symptom. Symptoms usually stop when, or shortly after, menstruation begins.
