Xanomeline is a muscarinic acetylcholine receptor agonist with reasonable selectivity for the M1 and M4 subtypes.[1][2][3][4] It has been studied for the treatment of both Alzheimer's disease and schizophrenia, particularly the cognitive and negative symptoms,[5] although gastrointestinal side effects led to a high drop-out rate in clinical trials.[6][7] Despite this, xanomeline has been shown to have reasonable efficacy for the treatment of schizophrenia symptoms, and one recent human study found robust improvements in verbal learning and short-term memory associated with xanomeline treatment.[8]
