A fast-acting transdermal gel using a proprietary formulation of the nonsteroidal anti-inflammatory drug (NSAID) ketoprofen helps in reduced pain severity in patients with severe migraine with or without auracompared with placebo and had few adverse effects. The phase 2a trial results were presented at the American Academy of Neurology (AAN) 67th Annual Meeting. The study shows the pathogenesis of severe headaches that are due to neurogenic inflammation. If proved in large-scale trials, it may be new era in neurological practice and introduction of new topical treatment of migraine. Oral analgesics such as cyclooxygenase inhibitors reduce inflammation but cause undesirable gastrointestinal effects.
