Pimavanserin: a novel therapeutic approach to treat Parkinson’s Disease Psychosis
Abstract
PDP (Parkinson's disease psychosis) is a neuropsychological nonmotor manifestation that occurs in individuals as a result of Parkinsonism with the advancement of the disease. It is mainly characterized by delusions, hallucinations, and other cognitive features affecting the patient’s quality of life. Although the existing treatments for PDP have a lot of clinical experience, they focus mainly on reducing and regulating the cognitive features. Hence, it is difficult to minimize the exacerbation of motor dysfunction along with the existing motor complications of Parkinson's disease (PD). Previous medications also led to tremors and rigidity as undesirable effects with long-term use by blocking dopamine (D2) receptors. Moreover, patients with PD take several drugs to manage their motor symptoms, which may complicate their medication regimen, causing patient burden. Therefore, as an emergent pharmacotherapeutic approach, pimavanserin, which is a selective 5-HT2A receptor inverse agonist, shows promising benefits in managing disease conditions by reducing psychosis while avoiding motor worsening and other non-motor side effects. This distinguishes pimavanserin from other available therapies for PDP. This review analyzes all the previously and recently published research works that have evaluated the efficacy of pimavanserin in the clinical management of PDP with its screening and pharmacological properties.
