Pimavanserin.

Pimavanserin. Drugs Today (Barc). 2015 Nov;51(11):645-52 Authors: Hunter NS, Anderson KC, Cox A Abstract Pimavanserin (ACP-103) is a selective inverse agonist of the 5-hydroxytryptamine 2A (5-HT2A) receptor intended to treat patients with Parkinson's disease psychosis (PDP). Currently there are no FDA-approved medications in the United States for the treatment of PDP, although on September 2, 2014, the United States Food and Drug Administration granted breakthrough therapy status to pimavanserin, highlighting the unmet need for therapeutics in this class. Most antipsychotic medications worsen motor dysfunction due to dopamine antagonism, and all carry a black box warning for an increased risk of mortality in elderly patients with dementia-related psychosis. Data from phase II and phase III clinical trials suggest that pimavanserin is a safe and effective treatment option for PDP. Trial results indicate a significant reduction in hallucinations and delusions in patients with PDP without worsening motor symptoms. Additional studies are ongoing for the treatment of Alzheimer's psychosis, schizophrenia and insomnia. Such promising outcomes warrant a review of the available literature regarding pimavanserin and its use in the treatment of PDP symptoms. PMID: 26744739 [PubMed - in process]
