  • Comparison of the Change in IDS Symptom Scores Among Groups [ Time Frame: over duration of treatment, 4 menstrual cycles averaging 4 months after baseline visit ] [ Designated as safety issue: No ]
    IDS = Inventory of Depressive Symptomatology: measures depressive symptoms during the previous premenstrual phase with high internal consistency: sum of responses to 28 of 30 possible items each scored 0 to 3 points with total scoring (0=no symptoms, 84=most severe). This outcome is a measure of effect size between the two trial groups and the placebo group, with the placebo effect size value used as a reference.
  • Comparison of the Change in PMTS Symptom Scores Among Groups [ Time Frame: over duration of treatment, 4 menstrual cycles averaging 4 months after baseline visit ] [ Designated as safety issue: No ]
    PMTS = Premenstrual Tension Syndrome (Observer Rating) Scale: a clinician-administered retrospective scale developed for the study of PMS, a sum of responses to 10 items each with 4 points (0=no symptoms, 40=most severe). This outcome is a measure of effect size between the two trial groups and the placebo group, with the placebo effect size value used as a reference.
  • Comparison of the Change in CGI-S Symptom Scores Among Groups [ Time Frame: over duration of treatment, 4 menstrual cycles averaging 4 months after baseline visit ] [ Designated as safety issue: No ]
    CGI-S = Clinical Global Impression-Severity: a severity scale widely used in psychopharmacology research (1=normal not at all ill, 7=among most extremely ill). This outcome is a measure of effect size between the two trial groups and the placebo group, with the placebo effect size value used as a reference.
  • Comparison of the Change in DRSP Symptom Scores Among Groups [ Time Frame: over duration of treatment, 4 menstrual cycles averaging 4 months after baseline visit ] [ Designated as safety issue: No ]
    DRSP = Daily Record of Severity of Problems, which combines responses to 21 items each with scale: 1=no symptoms, 6=extreme. This outcome is a measure of effect size between the two trial groups and the placebo group, with the placebo effect size value used as a reference.
  • Comparison of the Change in CGI Improvement Scores Among Groups [ Time Frame: over duration of treatment, 4 menstrual cycles averaging 4 months after baseline visit ] [ Designated as safety issue: No ]
    CGI-I = Clinical Global Impression Improvement: the improvement subscale of CGI measuring change at each visit as compared to visit 1 (1=very much improved, 7=very much worse). This outcome is a measure of effect size between the two trial groups and the placebo group, with the placebo effect size value used as a reference.
First, 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. [ Time Frame: 6-7 months ] [ Designated as safety issue: No ]

Comparison of Fluoxetine, Calcium and Placebo for the Treatment of Moderate to Severe Premenstrual Syndrome (PMS)
A Double-blind, Parallel Comparison of Fluoxetine, Calcium and Placebo for the Treatment of Moderate to Severe Premenstrual Syndrome (PMS)

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.
