Objective: Antiparkinsonian pharmacotherapy is costly and the determinants of drug costs in Parkinson's disease (PD) have been poorly investigated. The objective of this study was to investigate the costs of PD and antiparkinsonian drugs in an Italian cohort of patients and identify cost-driving factors of drug therapy. Methods: Seventy outpatients with idiopathic PD were recruited in the Department of Neurology, Napoli University, Italy. Data on resource utilization were collected for 6 months using a bottom-up approach. Clinical status was evaluated using the Unified Parkinson's Disease Rating Scale. Direct and indirect costs were calculated from the societal perspective (figures of year 2009). Independent determinants of total costs and costs of antiparkinsonian drugs were identified using multivariate regression analysis. Results: The total costs of PD were EUR 8,640 (95% CI: EUR 6,700-11,240) per patient over a 6-month period. Direct costs accounted for 70% of the total costs. Antiparkinsonian drugs (EUR 1,450; 95% CI: EUR 1,220-1,760) were the primary component of costs paid by the health insurance (39.6%) and one of the most expensive components of the direct costs (24.0%). The highest copayments made by patients were for antiparkinsonian drugs and medical equipment (58%). Independent determinants of the increased costs of antiparkinsonian pharmacotherapy were younger age and occurrence of motor fluctuations. Conclusions: Antiparkinsonian pharmacotherapy is one of the major cost components of PD-related costs for health insurance. It imposes a considerable economic burden on patients and their families as well. Copyright (C) 2010 S. Karger AG, Basel
