Memantine is typically prescribed in much lower doses, commonly starting at 5mg or 10mg and rarely exceeding 20mg. It is primarily utilized for managing Alzheimer’s disease, exhibiting neuroprotective effects and reducing excitotoxicity associated with neurodegenerative disorders. As an NMDA receptor antagonist, Memantine regulates glutamate activity, crucial for learning and memory processes. Dosing is initiated low and gradually increased, with adjustments for renal impairment. Common side effects include dizziness and constipation, while severe reactions are rare. Caution is advised for individuals with seizure disorders, and continuous monitoring is recommended for those with cardiovascular conditions. Patients should adhere to prescribed doses and seek medical guidance for any concerns.

  1. Alzheimer’s Management: Memantine is a key component in treating Alzheimer’s disease, offering cognitive improvement and slowing mental decline.
  2. Neuroprotective Effects: It demonstrates neuroprotective properties, potentially shielding brain cells from damage.
  3. Excitotoxicity Regulation: As an NMDA receptor antagonist, Memantine modulates glutamate activity, reducing excitotoxicity linked to neurodegenerative disorders.

Working of Memantine: Memantine functions by regulating glutamate, a neurotransmitter vital for learning and memory. Acting as an NMDA receptor antagonist, it helps maintain optimal neurotransmission and protects against excitotoxicity.

Typically initiated at lower doses like 5mg or 10mg, Memantine is gradually increased based on patient response. Therapeutic doses can range from 5mg to 20mg per day, as directed by healthcare professionals.
