Patient Response to Treatment for Dysmenorrhea, as Evaluated by Difference of Total Dysmenorrhea Score (Baseline/Pretreatment-End of Treatment) [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]

The detail of dysmenorrhea score that was used in this study is the following. These subscales summed for a total dysmenorrhea score (minimum 0 to maximum 6). Pain score None 0 : None Mild 1 : There are some troubles for work Moderate 2 : Needing to rest in bed and/or affecting work Severe 3 : Morre than 1 day in bed and not possible to work

Phase 3
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Dysmenorrhea
Drug: NPC-01

This study consist of the following steps.

Step 1(Norethisterone 0.6mg, Ethinyl Estradiol 0.035mg):From first study medication to 3th menstrual cycles.

Step 2(Norethisterone 1mg, Ethinyl Estradiol 0.035mg):

After interim analysis of the results of step 1, in the case of the efficacy results meet prespecified criterion, same dose level will be continued to 13th menstrual cycles including step 1. If the results do not meet prespecified criterion, the dose will be increased to Norethisterone 1mg, Ethinyl Estradiol 0.035mg and be continued newly until 13th menstrual cycle from this point.
