What is Namenda Xr

Memantine

The Generic name of this drug

Treatment Summary

Memantine is a medication used to treat Alzheimer’s Disease. It works differently from other Alzheimer’s medications by blocking glutamate, a chemical in the brain which can cause excessive stimulation in Alzheimer’s Disease. The drug was approved by the FDA in 2013 and the number of people living with Alzheimer’s Disease worldwide has been steadily increasing since then. In 2013, the G8 dementia summit concluded that dementia should be a priority and that a cure or a disease-modifying therapy should be developed by 2025.

Effectiveness

How Namenda Xr Affects Patients

Memantine helps to improve Alzheimer's dementia symptoms such as cognition. At lower doses, it can help with memory and protect neurons from damage caused by certain neurotransmitters. It does not interact with most other receptors, such as those for GABA, dopamine, or adrenaline. In lab studies, it has been shown not to interfere with medications such as donepezil, galantamine, or tacrine.

How Namenda Xr works in the body

Memantine is used to treat Alzheimer's disease by blocking overactive N-methyl-D-aspartate (NMDA) receptors in the brain. These receptors are normally stimulated by a chemical called glutamate, but too much of it can be toxic to the brain. Memantine stops glutamate from overstimulating these receptors, thus preventing neurotoxicity. While this is not a cure for Alzheimer's, it can help slow down the neurodegeneration associated with the disease.

Namenda Xr Toxicity & Overdose Risk

The toxic dose of memantine in mice is 437-498 mg/kg and in rats is 328-370 mg/kg. No evidence of cancer or genetic damage was found in mice and rats given the drug. There were also no effects on fertility or reproductive performance in animals given the drug. Memantine is a pregnancy category B drug, meaning that it has not been adequately studied in pregnant women and should only be used if the potential benefits outweigh the possible risks to the fetus. It is unknown if memantine is passed into breast milk, so caution should be taken when it is used by nursing mothers.

Patient Review

Namenda Xr for Moderate to Severe Alzheimer's Type Dementia

My husband takes the XR and Aricept together, and they work really well for him. He's able to function normally but doesn't have much energy or enthusiasm. I think he's just being lazy, but I understand that it's a side effect of his illness.

Namenda Xr for Moderate to Severe Alzheimer's Type Dementia

I've been on this medication for three weeks and I've noticed that after taking it for six hours, I feel an urge to clean. Afterward, however, I become very sleepy. Additionally, I sometimes have nightmares; though they're not too bad. Overall, this drug has helped me more than it's hurt me.

Namenda Xr for Moderate to Severe Alzheimer's Type Dementia

This medication caused my mother to regress; she stopped eating and her days and nights were reversed. She was also constantly crying, tearful, confused, and seeing things that weren't there. I had to take her off the medication immediately, but thankfully she's doing much better now.

Namenda Xr for Moderate to Severe Alzheimer's Type Dementia

My dad has been taking this medication and it's made him want to sleep all the time. He's much more sedentary now and isn't able to do tasks he could before. This is really tough on my mom who is his primary caregiver. I think they're going to talk to the doctor about taking him off the medication soon.

Namenda Xr for Moderate to Severe Alzheimer's Type Dementia

Since my mother started this medication, she's been having terrible nightmares and repeating herself constantly. I contacted her doctor and they said it wasn't the medicine, but I don't think that's true. This morning she thought people were in her room and when I told her she was dreaming, she didn't believe me. It's so sad to see what this has done to her.

Namenda Xr for Moderate to Severe Alzheimer's Type Dementia

My husband became very confused and disoriented after only four days on this medication. He stopped taking it immediately, and within 10 days was back to his old self. We were both very relieved. I would not recommend this drug to anyone.

Clinical Trials for Namenda Xr

Photobiomodulation for Alzheimer's Disease

55 - 89
All Sexes
Los Angeles, CA

The purpose of this study is to see if a special light treatment, called photobiomodulation, can help people with memory problems such as Mild Cognitive Impairment or Mild Dementia due to Alzheimer's disease. The light is given to the forehead using an FDA-cleared medical device. This device is cleared to provide topical heating to elevate tissue temperature for temporary relief of muscle and joint pain, muscle spasm and stiffness associated with arthritis. It also increases blood circulation and relaxes muscle tissue. This device is being used "off-label," meaning it will be used in a way that is different than its cleared use. We want to learn whether this light treatment can improve executive function, and whether it changes certain inflammatory and neurodegeneration related signals in the blood. To do this, we will apply the photobiomodulation device to your forehead. We will also ask you questions and give you cognitive tests before and after light treatment. We will also collect blood samples before and after treatment.

Lifestyle Intervention for Alzheimer's Disease

65 - 75
All Sexes
Huntsville, AL

Many individuals develop dementia, and dementia has multiple causes, yet we currently have limited treatment options. A critical observation of the effectiveness of the available dementia treatments is that they tend to be more effective when started early. Previous studies have shown that multimodal lifestyle interventions can significantly delay the onset of Alzheimer's dementia in individuals with high risk for Alzheimer's or with Mild Cognitive Impairment (MCI). These interventions may be less effective when initiated after dementia has already been diagnosed or is more advanced. This study has two primary goals. The first goal is to assess attitudes around dementia risk for participants throughout the study as they learn of their personalized risk and possible lifestyle factors that may modify that risk. The second goal is to serve as a logistical pilot for the implementation of data collection and processing and multimodal lifestyle intervention to reduce the risk factors of dementia in individuals without current cognitive impairment but who are at high risk of progression to dementia. Secondary goals of this study include better defining what factors contribute the most risk to dementia and identifying sub-types of dementia defined by different genetic and molecular risk factors.
