Abstract

Introduction: Pimavanserin (Nuplazid™) is an atypical antipsychotic currently indicated for the treatment of hallucinations and delusions associated with Parkinson disease psychosis. The antipsychotic effects of this new agent are believed to occur via selective inverse agonist activity at serotonin 5-HT2a receptors.

Methods: Study authors completed a literature review of 2 published randomized controlled trials of pimavanserin for the treatment of Parkinson disease psychosis. The Food and Drug Administration Briefing Document by the Psychopharmacologic Drugs Advisory Committee for the review of pimavanserin dated March 29, 2016, was reviewed for additional information on 2 unpublished trials.

Results: Pimavanserin has demonstrated no worsening of motor symptoms of Parkinson disease, but only 1 of 4 trials has shown consistent statistically significant improvements in psychotic symptoms compared with placebo.

Discussion: Options for the treatment of Parkinson disease psychosis are limited. The selective receptor profile of pimavanserin offers advantages for tolerability. Further studies are warranted to better provide clinicians and patients with information regarding the clinical utility of this agent.

Keywords: Parkinson disease; Pimavanserin; psychosis.
