Effect of L-Dihydroxyphenylserine (L-DOPS) on Falls in Patients With Neurogenic Orthostatic Hypotension (NOH)

This will be a Phase II single center, double-blind, randomized, placebo-controlled, efficacy study. Subjects will complete six visits. The first will be a screening visit. There will be four assessment visits: baseline, 2 weeks after the double-blinded trial begins, the end of the blinded trial, and after 4 weeks of washout. There will also be an additional randomization and medication dispensing visit immediately following the dose optimization period and preceding the double-blinded trial.
