Manufacturer:
Forest Laboratories Inc.

Treatment for:
moderate to severe Alzheimer's disease

The U.S namenda and side effects and hand tremors. Food and Drug Administration (FDA) has approved Namenda (memantineHCl) for the treatment of moderate to severe Alzheimer's disease namenda and side effects and hand tremors. Namenda isthe first NMDA receptor antagonist to be approved for Alzheimer's disease andis also the only therapy approved for the treatment of moderate to severe Alzheimer'sdisease.
Forest expects Namenda to be available to physicians, patients, and pharmaciesin January 2004.

Namenda's FDA approval is based on the Agency's review of safety and efficacydata from two U.S namenda and side effects and hand tremors. placebo-controlled Phase III clinical trials and an earliertrial conducted among nursing home patients in Europe namenda and side effects and hand tremors. Phase III data includeda 28-week monotherapy study of 252 patients published earlier this year in theNew England Journal of Medicine and a six-month, 401-patient study of Namendawhen used together with an ongoing regimen of the commonly used Alzheimer'sagent, donepezil namenda and side effects and hand tremors. In trials, patients treated with Namenda scored higher onmeasures of cognition, daily function, and/or global performance namenda and side effects and hand tremors. This developmentprogram for memantine was a joint effort between Forest and its licensor, MerzPharmaceuticals, who obtained centralized approval for memantine in the EuropeanUnion in 2002 namenda and side effects and hand tremors. Merz Pharmaceuticals is a specialty pharmaceutical company dedicatedto research and development in the fields of neurology and psychiatry.

In clinical trials, Namenda has been safe and well tolerated namenda and side effects and hand tremors. The most commonadverse events observed in clinical trials are dizziness, headache, constipation,and confusion namenda and side effects and hand tremors. Once available in pharmacies, Namenda will be administered orallyat a recommended dose of 10 mg BID following a four-week titration.

Alzheimer's is a progressive disease of the brain and it is the most commontype of dementia namenda and side effects and hand tremors. The term dementia is used to describe the progressive lossof cognitive, intellectual, or functional abilities namenda and side effects and hand tremors. Published reports projectthat by 2010 more than 5.1 million people in the United States will have Alzheimer'sdisease namenda and side effects and hand tremors. Currently, all Alzheimer's medications approved in the United Statesbelong to a class of agents called acetylcholinesterase inhibitors, which areindicated for patients with mild to moderate symptoms of the disease namenda and side effects and hand tremors. Namendais the only approved therapy in the United States for moderate to severe Alzheimer'sdisease.

Mechanism of Action

Namenda (memantine HCl) is the first of a new class of medications for Alzheimer'sdisease with a mechanism of action distinct from currently available drugs namenda and side effects and hand tremors. Namenda is a low to moderate affinity NMDA (N-methyl-D- aspartate) receptorantagonist namenda and side effects and hand tremors. It is thought that overexcitation of NMDA receptors by the neurotransmitterglutamate may play a role in Alzheimer's disease since glutamate plays an integralrole in the neural pathways associated with learning and memory namenda and side effects and hand tremors. The excitotoxicityproduced by abnormal levels of glutamate is thought to be responsible for neuronalcell dysfunction and the eventual cell death observed in Alzheimer's disease namenda and side effects and hand tremors. Namenda is thought to selectively block the excitotoxic effects associated withabnormal transmission of glutamate, while allowing for the physiological transmissionassociated with normal cell functioning.
