Summary for Patent: 8,338,486
Title:Methods for the treatment of CNS-related conditions
Abstract: The invention provides methods for administering extended release memantine in combination with immediate release donepezil to a subject. Memantine in an extended release form containing 22.5 to 30 mg memantine or a pharmaceutically acceptable salt thereof in combination with donepezil is administered to a patient suffering from a neurological condition, such as Alzheimer's disease, Parkinson's disease or dementia. The extended release form of memantine 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.
