DEER PARK, Ill., June 28, 2023 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc (Nasdaq: ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, announced today that the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) in response to its New Drug Application (NDA) for dehydrated alcohol injection for the treatment of methanol poisoning.
