Migraine treatment includes both preventive therapy, aimed at reducing attack frequency and severity, and acute therapy, for aborting attacks. For acute therapy, the most widely used drugs are NSAIDs and triptans. Routes of triptan administration include oral, intranasal, suppository, subcutaneous, and transdermal iontophoretic, as well as a variety of device-enhanced delivery options. Relatively slow onset of action remains a limitation for these formulations, except for the injectable delivery. Novel routes of delivery, such as intradermal, are in development, holding the promise of rapid absorption into the systemic circulation and, thus, rapid relief. Ultimately, the abundance of delivery options provides more choices to patients with migraine.
