Abstract

SUMMARY We will describe the pharmacokinetic profile, clinical efficacy and safety data of the sumatriptan iontophoretic transdermal system (Zecuity®, NuPathe Inc., PA, USA), recently approved for the acute treatment of migraine with or without aura in adults, by the US FDA. This transdermal system utilizes a low-level electrical current to deliver sumatriptan transdermally and circumvents the GI tract. Pharmacokinetic studies have shown that iontophoretic delivery of sumatriptan achieves detectable plasma concentrations 15 min after activation with a maximum mean serum concentration of 22 ng/ml. A randomized, double-blind, controlled clinical trial demonstrated minimal triptan-related side effects and superior efficacy versus placebo. The pain-free rate at 2 h postdose was 18% of patients applying the sumatriptan patch versus 9% using the placebo (p = 0.0092). This sumatriptan transdermal system may be a good choice for migraineurs with severe nausea or vomiting, those with intolerable triptan-related adverse events and/or those not responding optimally to oral medications.
