Primary Outcome Measures:
  • Overall analgesic effect as measured by the total pain relief score over 8 hours post dose (TOPAR8), sum of pain intensity difference over 8 hours post dose (SPID8), and patient's global evaluation at 8 and 24 hours post dose compared with placebo [ Time Frame: Up to 8 hours postdose and at 8 and 24 hours postdose, following onset of moderate-to-severe pain due to primary dysmenorrhea for each of three consecutive menstrual cycles ] [ Designated as safety issue: No ]
  • Time to onset, peak, and duration of the analgesic effect compared with placebo [ Time Frame: to 24 hours following onset of moderate-to-severe pain due to primary dysmenorrhea for each of three consecutive menstrual cycles ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Overall analgesic effect, time to onset, peak, and duration of analgesic effect compared with naproxen sodium [ Time Frame: Up to 24 hours following onset of moderate-to-severe pain due to primary dysmenorrhea for each of three consecutive menstrual cycles ] [ Designated as safety issue: No ]
  • Overall analgesic effect, time to onset, peak, and duration of analgesic effect of naproxen sodium compared with placebo [ Time Frame: Up to 24 hours following onset of moderate-to-severe pain due to primary dysmenorrhea for each of three consecutive menstrual cycles ] [ Designated as safety issue: No ]
  • Safety and tolerability of etoricoxib as assessed by the number of patients with clinical or laboratory adverse experiences [ Time Frame: From randomization through 14 days following the last dose of study medication ] [ Designated as safety issue: Yes ]
