Primary Outcome Measures :
  1. Safety - Number of Participants With Adverse Effects [ Time Frame: End of Study - 7 weeks ]
    The primary outcome measure for this study was the assessment of adverse events as unanticipated or anticipated.

Secondary Outcome Measures :
  1. Mean Change in Headache Pain From Baseline to 120 Minutes [ Time Frame: 120 minutes ]

    Headache was measured on a 4 point scale where 0 = no pain, 1 = mild, 2 = moderate, 3 = severe pain at baseline (start of attack), 5, 15, 30, 45, 60, 90 and 120 minutes.

    Data presented shows the average change from baseline to 120 minutes

  2. Change in Photophobia (Visual) From Baseline to 120 Minutes [ Time Frame: Base line and 120 minutes ]
    Presence of photophobia (yes or no) was captured at baseline and 120 minutes.

  3. Change in Phonophobia (Auditory) From Baseline to 120 Minutes [ Time Frame: Baseline and 120 minutes ]
    Presence of phonophobia (yes or no) was captured at baseline and 120 minutes.

  4. Mean Change in Nausea From Baseline to 120 Minutes [ Time Frame: Baseline 120 minutes ]
    Nausea was captured in the diary and measured on a 4 point scale, where 0 = no nausea, 1 = mild, 2 = moderate and 3 = severe nausea, at baseline and 120 minutes.

  5. Mean Change in Functional Disability [ Time Frame: Baseline and 120 minutes ]
    Functional disability was captured in the diary and measured on a 4 point scale, where 0 = no disability, able to function normally and where 3 = performance of daily activities severely impaired, measured at baseline and 120 minutes.
