  • The N-methyl-d-aspartate (NMDA) receptor antagonist memantine is an approved drug for treatment of Alzheimer's disease (AD). Other such treatments are cholinesterase inhibitors and nicotinic acetylcholine receptor (nAChR)-sensitizing agents such as galantamine. The present study was designed to test whether memantine exerts any effect on the cholinergic system, in particular the Ca2+-conducting α7* nAChR, in cultured hippocampal neurons. Memantine caused a concentration-dependent reduction of… CONTINUE READING
