摘要

Background: Drug adherence decreased in patients with Parkinson’ s disease (PD) because of taking many different types of drugs. We evaluated drug adherence after switching from immediate-release (IR) to once-daily extended-release (ER) pramipexole (PPX) in PD. Methods: This study included 35 PD patients (20 men, 15 women);10 were taking oral PPX alone, and 25 were also using another anti-PD drug. PPX-IR was switched overnight to PPX-ER without gradual tapering. One month after switching, improvement in timing adherence and reduction in medication burden were evaluated by a questionnaire using a visual analog scale (VAS) (0: No change;10: Better). Motor function was assessed using part III of the Unified Parkinson’s Disease Rating Scale (UPDRS). Results: The VAS score for improvement in timing adherence was 8.1 ± 0.5 (mean ± standard error), and that for reduction in medication burden was 7.3 ± 0.6. There was a significant negative correlation (ρ = -0.43, p = 0.01) between the VAS score and number of types of medications. The UPDRS part III score improved significantly after switching (p
