NCT03229174
This is a double blind placebo controlled trial in Parkinson's disease (PD) patients with neurogenic orthostatic hypotension (NOH). Investigators hypothesize that the study drug (droxidopa) may improve cerebral perfusion more robustly than systemic BP, possibly by direct action within the CNS vasculature. This study is designed to determine if droxidopa improves cerebral perfusion measures in PD patients with NOH, in addition to peripheral BP measures and subjective responses.
