Name Time Method Main Objective: To evaluate the efficacy of MK-0462 compared to placebo in the treatment of acute migraine in patients on topiramate for migraine prophylaxis, as measured by the proportion of treated attacks resulting in pain relief (PR) at 2 hours post-dose.;Secondary Objective: To evaluate the efficacy of rizatriptan compared to placebo in the treatment of acute migraine in patients on topiramate for migraine prophylaxis as measured by: (1) Sustained pain relief (SPR) from 2-24 hours post dose; (2) pain freedom (PF) at 2 hours post-dose; (3) Functional disability at 2 hours post-dose; (4) Patient satisfaction with treatment at 24 hours post-dose.;<br> Primary end point(s): Efficacy: Pain relief (PR) at 2 hours post-dose, with pain relief defined as a reduction in headache severity from Grade 3/2 at baseline to Grade1/0.<br> Safety: Safety and tolerability will be assessed by review of all safety parameters, including adverse experiences and vital signs.<br>
