D797 + memantine

D797 + memantine refers to a combination of two active substances. Memantine is a small molecule N-methyl-D-aspartate (NMDA) receptor antagonist used primarily in the treatment of moderate-to-severe Alzheimer's disease, acting by blocking the effects of excessive glutamate to prevent neurotoxicity and slow the progression of symptoms[2]. D797 does not correspond to a recognized or approved drug in public pharmaceutical databases or literature as of this request and thus its mechanism, indication, and chemical class cannot be established from available information. There is no evidence for a branded or investigational combination product containing D797 and memantine.
