Most antipsychotics approved for schizophrenia interact with D2 dopamine receptors as an important part of their mechanism of action. While antipsychotics blocking D2 dopamine receptors can be effective for positive symptoms of schizophrenia, none are approved by regulatory authorities for predominant negative or cognitive symptoms. Moreover, many of these agents induce a range of problematic side effects related to D2 dopamine receptor blockade (e.g., drug-induced parkinsonism, akathisia, tardive dyskinesia, hyperprolactinemia and related sexual side effects, sedation). This has prompted the search for novel mechanisms with improved efficacy and tolerability based on evidence supporting involvement of other neurotransmitter systems in schizophrenia pathophysiology, including acetylcholine, gamma-aminobutyric acid, and glutamate. Among these options, targeting muscarinic receptors emerged as a promising treatment strategy. In September 2024, the U.S. Food and Drug Administration approved xanomeline and trospium chloride for treatment of adults with schizophrenia based on results from three 5-week, randomized, double-blind, placebo-controlled trials and two 52 week open-label trials. In the placebo-controlled trials, xanomeline/trospium reduced symptoms of schizophrenia, was generally well tolerated, and was not associated with clinically meaningful motor symptoms, hyperprolactinemia, sexual side effects, or weight gain compared with placebo. The long-term safety of xanomeline/trospium was also confirmed in two 52-week, open-label trials.
