Placebo Comparator: Placebo |
Drug: Placebo
Subjects were randomized to one of the 3 treatment groups (eletriptan 40 mg, eletriptan 80 mg, or placebo) in a 2:2:1 ratio and were given sufficient medication to treat 3 migraine attacks (including a second dose for each attack for recurrence) within 18 weeks of the initial visit. Subjects were instructed to treat a moderate to severe migraine within 6 hours of the onset of pain provided the headache was not decreasing in severity, the aura phase had ended and they had taken no analgesic or antiemetic within 6 hours. Efficacy data was collected in a diary. Subjects were allowed to take rescue medication if they had no response to the study medication within 4 hours of onset. |

Drug: Eletriptan 80 mg

Efficacy data was collected in a diary. Subjects were allowed to take rescue medication if they had no response to the study medication within 4 hours of onset. |
- The primary efficacy endpoint was 2-h headache response after taking the first dose of study medication for the first attack [ Time Frame: 18 weeks ]Subjects recorded the intensity of each migraine headache in the diary based on a 4-point scale: 0, pain absent; 1, mild pain; 2, moderate pain; 3, severe pain. A response was considered a change from severe or moderate pain to mild or absent at various time points after dosing with study medication
- Sustained response was defined as achieving a headache response within 2 h post dose, with no recurrence or rescue medication needed [ Time Frame: 18 weeks ]Recurrence was defined as a return of headache to moderate or severe intensity within 2-24 h if the subject had an initial response within 2 h of taking the study medication.
