Allergan Inc., the maker of the Botox wrinkle treatment, failed to win U.S. approval for its inhalable version of a 60-year-old migraine drug after regulators raised concerns about manufacturing.
The Food and Drug Administration rejected Allergan’s Levadex, an inhaled form of dihydroergotamine, as an acute treatment for patients suffering from migraine attacks, the Irvine, California-based company said today in a statement. If approved, the use of Levadex would not be limited by the monthly number of migraines suffered by a patient as Botox is, Heather Katt, an Allergan spokeswoman, said in an e-mail.
