Rapid systemic delivery of zolmitriptan using an adhesive dermally applied microarray.

Adhesive Dermally-Applied Microarray (ADAM) is a device for intracutaneous drug administration consisting of a 3 cm2 disposable array of drug-coated titanium microprojections on an adhesive backing. It is applied using a low cost, reusable, handheld applicator. Microprojections penetrate the stratum corneum, delivering drug proximal to capillaries with limited likelihood of pain. The pharmacokinetics of zolmitriptan delivery using ADAM was evaluated in 20 healthy volunteers. Median tmax was <20 min, comparable to subcutaneous sumatriptan. Absorption was faster than for oral zolmitriptan, with higher exposure in the first 2 h. Most adverse events were consistent with those seen in previous triptan trials. Application site reactions were generally mild and resolved within 24 h. ADAM zolmitriptan shows a promising pharmacokinetic profile for migraine treatment.
