Summary
The purpose of this study is to determine a recommended dose of topiramate in participants
with migraine (type of severe headache that occurs periodically and is often associated with
nausea, vomiting, and constipation or diarrhea), to verify the superiority (statistically
more effective) of the drug to placebo (an inactive substance that is compared with a drug to
test whether the drug has a real effect in a clinical trial), and to assess if a same
therapeutic effect can be observed between this study and overseas Caucasian clinical
studies.
