Eligibility criteria:

        Inclusion Criteria:

          -  Subjects who were informed of the nature of the study and agreed to read, review, and
             sign the informed consent document prior to Period I dosing.

          -  Subjects who completed the screening process within 28 days prior to Period I dosing.

          -  Subjects who were healthy adult menstruating women 18 to 35 years of age, inclusive,

             and gynecological exam in the previous 12 months (prior to study Day 1) and
             documentation of acceptable results were provided, both were deferred. Any
             abnormalities/deviations from the normal range which were considered clinically
             relevant by the study physician and investigator were evaluated for individual cases,
             documented in study files, and agreed upon by the study physician and investigator
             prior to enrolling a volunteer in this study and for continued enrollment.

             birth control methods included: double barriers, non-hormonal releasing intrauterine
             device in place for at least 30 days prior to dosing, abstinence throughout the
