Summary

This is a study to determine the overall analgesic effect of a single oral dose of etoricoxib compared to ibuprofen in participants with moderate-to-severe primary dysmenorrhea.

Eligibility Criteria

Inclusion Criteria

  • Agree to remain abstinent or use double-barrier contraception throughout the study. Participants who are status post tubal ligation are exempt from this requirement.
  • Moderate or severe primary dysmenorrhea during a minimum of 4 of the previous 6 menstrual cycles. Moderate: Over-the-counter analgesics provide significant relief in most menstrual cycles; discomfort interferes with usual activity. Severe: Over-the-counter analgesics not consistently effective, or prescription analgesics required in at least some menstrual cycles; discomfort is incapacitating causing an inability to work or do usual activity.
  • Willing to limit alcohol intake to 2 drinks or equivalent per day for the duration of the study and follow-up period as well as to avoid exercise during the first 24 hours postdose in each menstrual cycle.
  • Able to read, understand, and complete diary.

Exclusion Criteria

  • Use of an intrauterine device. Pregnant, breast feeding, or or equal to 5 years prior to screening. Participants with a history of leukemia, lymphoma, malignant melanoma, and myeloproliferative disease are ineligible for the study regardless of the time since treatment.
  • Allergic to etoricoxib, ibuprofen, acetaminophen, indomethacin, or other nonsteroidal anti-inflammatory drugs (NSAIDs), or cyclooxygenase (COX)-2 inhibitors, or to components in Saridon (propyphenazone/paracetamol/caffeine).
  • Recent history of chronic analgesic or tranquilizer use or dependence.
  • Morbidly obese and demonstrates significant health problems stemming from the obesity.
  • Current user of recreational or illicit drugs or had a recent history of drug or alcohol abuse or dependence.
  • Participated in another clinical study within the last 4 weeks.
  • Not able to swallow oral medications: surgical or anatomical conditions that will preclude from swallowing and absorbing oral medications on an ongoing basis.
