ALISO VIEJO, Calif., Nov. 17, 2011 /PRNewswire/ -- Avanir Pharmaceuticals, Inc. (NASDAQ: AVNR) announced today that the European Medicines Agency (EMA) has accepted the filing of the Marketing Authorization Application (MAA) for NUEDEXTA® (dextromethorphan HBr and quinidine sulfate) for the treatment of pseudobulbar affect (PBA). Acceptance of the MAA confirms that the submission is sufficiently complete to permit a substantive review.
NUEDEXTA was approved by the U.S. Food and Drug Administration in October 2010 for the treatment of PBA, a neurologic condition which is characterized by frequent outbursts of involuntary crying or laughing.

Additionally the company received notification from the EMA that the Name Review Group and the Committee for Medicinal Products for Human Use had no objections to the proposed use of the trade name NUEDEXTA.
