Two new migraine drugs show some promise. Instead of stopping a headache once it's already started, these drugs may prevent the migraine from occurring. Scientists say the drugs block a protein known to trigger migraines.
In a study of about 400 people, patients had four additional migraine-free days a month with one drug and nearly six extra days with the other. However, migraines also declined in those taking placebo, but not as dramatically.
Researchers say larger studies are needed and use of the drugs is several years away.
