Method for administering an NMDA receptor antagonist to a subject

摘要

The invention provides methods for administering memantine to a subject. Memantine in an extended release form containing 22.5 to 30 mg memantine or a pharmaceutically acceptable salt is administered to a patient suffering from a neurological condition, such as Alzheimer's disease, Parkinson's disease or dementia. The extended release form achieves particular pharmacokinetic criteria such as change in plasma concentration of memantine over time and ratio of maximum memantine plasma concentration to mean memantine plasma concentration.
