An iontophoretic transdermal system (ITS) (skin patch) formulation of sumatriptan for the acute treatment of migraine attacks was approved by the US Food and Drug Administration in January 2013. This transdermal system bypasses the gastrointestinal tract, as it uses low electrical current to move sumatriptan transdermally into the subcutaneous tissue. Randomized, double-blind, controlled clinical trials have demonstrated minimal triptan-related side effects and superior efficacy versus placebo, comparable with other sumatriptan formulations. Sumatriptan ITS can be applied successfully during a mild or severe migraine attack. According to pharmacokinetic properties and clinical data, sumatriptan ITS may be a good choice for people with migraine and severe nausea, vomiting or gastroparesis, those with intolerable triptan-related adverse events and those not responding optimally to oral medications.
