Whatever Happened to Levadex?
We’ve been talking about the new migraine drug, Levadex, since 2010. But it’s still not on the market. Will it ever be?
Levadex was still in the news last year, but under a brand new name. Semprana is the new name for Levadex, a new formulation of dihydroergotamine mesylate (DHE). It’s now owned by Allergan, the makers of Botox.
Semprana is an inhaled migraine abortive. It looks especially promising for nausea, and sensitivity to light and sound.
But last summer, Semprana was rejected yet again by the FDA in the United States. That’s the third time. The good news is that the rejection had nothing to do with whether or not Semprana works, or whether or not it’s safe. Instead, the FDA had technical concerns about the manufacturing and functioning of the device.
Semprana remains in Allergan’s pipeline, and is still looking like it could be a big player in the migraine market. But consumers probably won’t be seeing it in the local pharmacy until 2017.

This, of course, does not mean that these medications will work the best for you. There is a lot of variation within migraine, and your doctor will help you decide where to start.
Triptans were gradually introduced into the market starting in 1991 with sumatriptan. But this gradual release has perhaps caused some problems which are true for migraine patients but magnified when it comes to cluster.
The phase III trials demonstrated that the medication and delivery system work, providing relief as early as 15-30 minutes after use, with most patients finding relief and nearly 20% completely free of migraine symptoms at 1 hour.
