OBJECTIVES: The 'short' and 'long-term' benefits of pharmacological interventions
to treat orthostatic hypotension (OH) remain unclear. The aim was to
systematically examine the published literature on the effectiveness of different
drug regimens for the treatment of OH.
DESIGN: Systematic review.
SETTING: MEDLINE (1950-Week 7, 2011), EMBASE (1980-Week 7, 2011), CINAHL
(1981-Week 7, 2011) databases and hand-searching of bibliographies were used to
identify suitable papers.
PARTICIPANTS: Studies selected were those, which investigated drug treatment of
OH in a single- or double-blind randomised controlled trial (RCT) in humans over
18 years of age.
MEASUREMENTS: Data were extracted from suitable full-text articles by three
investigators independently.
RESULTS: The 13 trials met the criteria for systematic review amongst which was
considerable variation in the size of postural blood pressure (BP) change with
active treatment. However, there was evidence that commonly used drugs midodrine
or fludrocortisone therapy did increase standing or head-up-tilt (HUT) systolic
blood pressure in certain patient groups.
CONCLUSION: The evidence that pharmacological therapy is of benefit for the
treatment of OH is limited by the lack of good quality clinical trial evidence.
Further well-designed RCTs of pharmacological treatment of OH investigating the
impact on postural symptoms as well as actual BP changes are needed.
