Phase II Study of Midodrine for Neurogenic Orthostatic Hypotension

OBJECTIVES: I. Study further the safety and efficacy of the alpha-receptor agonist midodrine in patients with neurogenic orthostatic hypotension.

II. Assess the quality of life in these patients with this treatment regimen.

Study Overview

• Status: Completed
• Conditions: Orthostatic Hypotension
