Migraine

Recent advances in migraine therapy include the recognition of analgesic or ergotamine abuse as a cause of chronic daily migraine, the introduction of effective non-narcotic drugs such as chlorpromazine, dihydroergotamine and corticosteroids for the treatment of intractable migraine attacks, the increased number of beta-blockers now recognized as effective prophylactic agents and the introduction of calcium-channel blockers for prophylaxis. There is a sufficient variety of antimigraine drugs, and therapy should be successful for most sufferers.
