Oka H, et al. - Given that the effect of rotigotine on daily blood pressure (BP) fluctuations might reflect autonomic failure in patients with Parkinson’s disease (PD), the researchers assessed the impacts on cardiovascular autonomic responses and circadian rhythm in patients with PD. For this analysis, 25 PD patients who were receiving rotigotine and 12 patients not receiving rotigotine were selected. The present data indicated that rotigotine improves the abnormal circadian rhythm of BP in patients with PD. They reported that rotigotine was suggested to have favorable effects on cardiovascular autonomic responses and circadian rhythm in patients with PD.
