Current Treatments for Migraine
Triptans are the most commonly prescribed drugs for the treatment of moderate to severe migraine. There are seven triptans approved for use and Imitrex®, marketed by GlaxoSmithKline, dominates the market. Other triptans are: Zomig®, Maxalt®, Amerge®, Frova, Axert®, and Relpax®. Patients who suffer from a mild migraine, or are unaware that their headache is a migraine, generally treat themselves with an over-the-counter analgesic such as aspirin or ibuprofen.
