Muscarinic Cholinergic Receptor Agonist and Peripheral Antagonist for Schizophrenia

Abstract

In a 5-week trial, xanomeline-trospium resulted in a greater decrease in the PANSS total score than placebo but was associated with cholinergic and anticholinergic adverse events. Larger and longer trials are required to determine the efficacy and safety of xanomeline-trospium in patients with schizophrenia.
