DEER PARK, Ill. and WOBURN, Mass., Nov. 08, 2021 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals Inc (Nasdaq: ETON) and Azurity Pharmaceuticals, Inc. today announced that the U.S. Food and Drug Administration (FDA) has approved EPRONTIA™ (topiramate) oral solution, 25mg/mL.

EPRONTIA™ has been approved as a monotherapy for treatment of partial-onset or primary generalized tonic-clonic seizures in patients 2 years of age and older; an adjunctive therapy for treatment of partial-onset seizures, primary generalized tonic-clonic seizures or seizures associated with Lennox-Gastaut syndrome in patients 2 years of age and older; and as a preventive treatment of migraine in patients 12 years of age and older.
