Zelrix is a transdermal patch containing sumatriptan for the treatment of acute migraine headache developed by NuPathe, a pharmaceutical company specializing in the treatment of neurological and psychiatric disorders. The patch is based on NuPathe’s proprietary SmartRelief™ platform, which according to the manufacturer’s website is “a non-invasive technology that utilizes low-level electrical energy to transport drugs through the skin in a safe and effective manner. The rate and amount of drug delivered is controlled electronically, so that the patient receives consistent therapy each and every time. Iontophoresis is an established drug delivery technology with multiple applications currently being used by physicians.” The SmartRelief™ iontophoresis utilizes pre-programmed, embedded electronics in the patch to provide consistent therapeutic drug levels. This is very interesting technology with many potential applications. Imagine the uses in professional sports where iontophoresis is frequently utilized to administer NSAIDS and corticosteroids for the treatment of inflammation
