Memаntine is used primаrily in the treаtment оf mоderate tо severe Alzheimer's disease. It works by selectively binding to the NMDA (N-methyl-D-aspartate) receptors in the brain. Memantine is an uncompetitive antagonist of the NMDA receptor, which is a type of glutamate receptor. In uncompetitive inhibition, the inhibitor binds only to the enzyme-substrate complex (in this case, the NMDA receptor when it is already activated by glutamate and glycine), not to the enzyme alone. This binding reduces the receptor's activity, effectively decreasing the pathological overactivation caused by excessive glutamate, which is associated with neurotoxicity and the progression of Alzheimer's disease. By stabilizing the NMDA receptor in a closed state, Memantine helps protect neurons from excitotoxicity without completely blocking normal glutamate signaling, which is essential for learning and memory. This uncompetitive inhibitory mechanism allows Memantine to reduce abnormal glutamatergic activity while preserving physiological function, offering therapeutic benefits in neurodegenerative conditions. Given the following Lineweaver-Burke plot, what are the main changes in the kinetic parameters produced by different doses of Memantine?
