On December 27, 2016, Amphastar announced that its wholly-owned subsidiary Armstrong Pharmaceuticals, Inc. ("Armstrong") had received a complete response letter from the U.S. Food and Drug Administration ("FDA"), informing Armstrong that its New Drug Application for Primatene Mist, an epinephrine inhalation aerosol product, cannot be approved in its present form.  The FDA indicated that Armstrong should make further changes to the product's label and packaging and conduct another Human Factor validation study to assess consumers' ability to use the product without the guidance of a doctor or pharmacist. 

On this news, Amphastar stock has fallen as much as $2.05, or 10.03%, during intraday trading on December 27, 2016.
