Data from randomized controlled trials that enrolled patients with acute psychotic symptoms of schizophrenia were used to assess efficacy and tolerability outcomes for 23 primarily dopamine-receptor blocking antipsychotics and the muscarinic receptor agonist xanomeline–trospium. Nineteen second-generation antipsychotics included in the analysis were licensed in Europe and in the USA. Selected first generation drugs such as haloperidol, chlorpromazine, perphenazine, and sulpiride were also included.1
