Memantine is a medication primarily used in the treatment of Alzheimer?s disease, a progressive neurological disorder that affects memory, thinking, and behavior. It belongs to a class of drugs known as NMDA receptor antagonists.
Memantine works by blocking the activity of glutamate, a neurotransmitter involved in learning and memory processes. In Alzheimer?s disease, excessive glutamate activity can lead to damage and cell death in the brain. By blocking NMDA receptors, memantine helps regulate glutamate activity and may slow down the progression of symptoms associated with Alzheimer?s disease.
Memantine is available in various forms, including tablets and oral solutions. The typical starting dose for memantine in the treatment of Alzheimer?s disease is 5 mg once daily, with the dose gradually increasing over time. The maximum recommended dose is 10 mg twice daily (20 mg per day).
It?s important to take memantine exactly as prescribed by a healthcare provider. Do not increase or decrease the dose without consulting a doctor. The dosage and frequency of administration may vary depending on factors such as the individual?s age, weight, kidney function, and response to treatment.
Common side effects of memantine may include:

Dizziness
Headache
Confusion
Constipation
Cough
Hallucinations
Increased blood pressure

Serious side effects are rare but can occur. It?s essential to seek medical attention if you experience any unusual symptoms or side effects while taking memantine.
Memantine may interact with other medications, so it?s important to inform your healthcare provider about all medications, supplements, and medical conditions you have before starting treatment with memantine.
As with any medication, it?s crucial to discuss any questions or concerns with a healthcare provider before starting treatment with memantine. They can provide guidance specific to your situation and monitor your progress throughout treatment to ensure its safety and efficacy.
