Treatment of Orthostatic Hypotension

Brief Title

Treatment of Orthostatic Hypotension

Official Title

Treatment of Hypotensive Patients Having a Unique Pattern of Autonomic Symptoms

Brief Summary

      The purpose of this study is to try different medications in patients with low blood pressure
      and other problems with their involuntary (autonomic) nervous system. The pharmacological
      trials in this study will perhaps lead to more effective treatment. This study consists of
      single dose trials, dose selection trials, 5-day trials and chronic (approximately 2 months)
      trials.
    

Detailed Description

      We see many patients at the Autonomic Dysfunction Center who can be given a fairly definitive
      diagnosis, e.g., Orthostatic Intolerance, Pure Autonomic Failure, Multiple System Atrophy,
      and Baroreflex Failure. However, some patients present with a unique constellation of
      symptoms of autonomic dysfunction so that they do not fit into a diagnostic category. We
      hypothesize that a genetic cause exists in some of these patients. We further propose that
      our comprehensive evaluation of these patients will provide us with information on the
      pathophysiology of their condition and assist us in optimizing their treatment.
