NEW YORK, Jun 21, 2010 (BUSINESS WIRE) -- Forest Laboratories, Inc. /quotes/comstock/13*!frx/quotes/nls/frx (FRX 27.54, +0.35, +1.30%) and Merz Pharmaceuticals GmbH announced today that NAMENDA XR(TM) (memantine hydrochloride) was approved by the U.S. Food and Drug Administration for the treatment of moderate to severe dementia of the Alzheimer's type. NAMENDA XR is a 28 mg once-daily extended-release formulation of NAMENDA. The safety and efficacy of NAMENDA XR were established in a randomized, double-blind, placebo-controlled trial of 677 outpatients already taking a cholinesterase inhibitor. The results indicate that patients treated with NAMENDA XR experienced statistically significant benefits in cognition and clinical global status compared to placebo.
NAMENDA XR will be covered by U.S. Patent No. 5,061,703, which is listed in the Orange Book for NAMENDA and expires in April 2015. In addition, Forest owns pending patent applications related to NAMENDA XR. The companies are determining the appropriate commercialization strategy and market timing to ensure a successful franchise.
About Namenda XR

Important Safety Information
-- Namenda XR is contraindicated in patients with known hypersensitivity to memantine hydrochloride or to any excipients used in the formulation.
-- Caregivers should be instructed in the recommended administration (once per day) and about dose escalation (minimum interval of one week between dose increases).
-- Namenda XR has not been systematically evaluated in patients with a seizure disorder.
-- Namenda XR should be used with caution under conditions that raise urine pH (including alterations by diet, drugs and the clinical state of the patient). Alkaline urine conditions may decrease the urinary elimination of memantine, resulting in increased plasma levels.
-- A dosage reduction is recommended in patients with severe renal impairment.
-- Namenda XR should be administered with caution to patients with severe hepatic impairment.
-- In clinical trials, the most common adverse events occurring in at least 5% of patients treated with Namenda XR and at a greater frequency than placebo-treated patients were headache (6% vs 5%), diarrhea (5% vs 4%), and dizziness (5% vs 1%).
