Systematic review of the pharmacoeconomics of Parkinson disease medications

Abstract

ABSTRACTIntroduction: Parkinson’s disease (PD) causes progressive motor symptoms including tremor, rigidity, and bradykinesia, along with non-motor symptoms such as dementia, orthostatic hypotension, and depression. Over time, PD can lead to falls, disability, institutionalization, and caregiver burden. Its treatment is symptomatic and can be associated with high costs.Areas covered: The authors performed a literature search of PubMed, Web of Science, and Cochrane Library Current for English language PD pharmacoeconomic evaluations starting from 1 January 2000. The authors found 26 papers covering treatment of motor symptoms (n = 24), dementia (n = 1), and orthostatic hypotension (n = 1). The scope of literature was limited in that there were few articles overall.Expert opinion: Overall, the authors found a scarcity of primary PD pharmacoeconomic literature in the 21st Century. Given the myriad of PD motor and non-motor treatments, only 24 papers evaluating motor treatments and two papers evaluating non-motor treatments met our search criteria. More studies are clearly needed to better define the pharmacoeconomics of PD therapeutics.
