Primary Outcome Measures:
  • Cmax (Maximum Observed Concentration of Drug Substance in Plasma) [ Time Frame: Blood samples collected over a 60 hour period. ]
    Bioequivalence based on Cmax.

  • AUC0-t (Area Under the Concentration-time Curve From Time Zero to Time of Last Measurable Concentration) [ Time Frame: Blood samples collected over a 60 hour period. ]
    Bioequivalence based on AUC0-t.

  • AUC0-inf (Area Under the Concentration-time Curve From Time Zero to Infinity) [ Time Frame: Blood samples collected over a 60 hour period. ]
    Bioequivalence based on AUC0-inf.

  • Donation or significant loss of whole blood (480 mL or more) within 30 days or plasma within 14 days prior to dosing.
  • Positive test for HIV, Hepatitis B surface antigen or Hepatitis C antibody.
  • Positive test results for drugs of abuse at screening.
  • Evidence of vulvovaginitis or cervicitis (e.g. Bacterial vaginosis, vaginal candidiasis, Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhea, or history of Herpes simplex or human papillomavirus).
  • Vulvar or vaginal conditions that may affect absorption of the drug.
