Nonpharmacological treatment, fludrocortisone, and domperidone for orthostatic hypotension in Parkinson's disease

There is limited evidence for the treatment of orthostatic hypotension in idiopathic Parkinson's disease. The objective of this study was to determine the efficacy of three treatments (nonpharmacological therapy, fludrocortisone, and domperidone). Phase I assessed the compliance, safety, and efficacy of nonpharmacological measures. Phase II was a double-blind randomized controlled crossover trial of the two medications. Primary outcome measures consisted of the orthostatic domain of the Composite Autonomic Symptom Scale (COMPASS-OD), a clinical global impression of change (CGI), and postural blood pressure testing via bedside sphygmomanometry (Phase 1) or tilt table testing (Phase 11). For the 17 patients studied, nonpharmacological therapy did not significantly alter any outcome measure. Both medications improved the CGI and COMPASS-OD scores. There was a trend towards reduced blood pressure drop on tilt table testing, with domperidone having a greater effect. (c) 2007 Movement Disorder Society.
