Abstract

OBJECTIVE: To determine the best therapeutic strategy for the use of midodrine in patients with neurogenic orthostatic hypotension (NOH). BACKGROUND: Midodrine is a peripherally acting alpha-adrenergic agonist useful in the treatment of NOH. However, neither the most effective dosage of midodrine nor the required frequency of administration is established. DESIGN/METHODS: Midodrine dose-blood pressure response, pharmacokinetics, and duration of action were examined in a double-blind, placebo-controlled, four-way crossover trial. Twenty-five patients with NOH were randomized to receive on successive days placebo or midodrine 2.5, 10, or 20 mg. Blood pressures of patients in the supine and standing positions were measured sequentially. A global assessment of the patient's overall symptom improvement after each leg of the study was performed. Blood levels of midodrine and its active metabolite, desglymidodrine, were assayed. RESULTS: Midodrine significantly increased standing systolic blood pressure, with the increase peaking at 1 hour. There was a significant linear relation between midodrine dosage and mean systolic blood pressure. The mean score for global improvement of symptoms was significantly higher for midodrine (10 and 20 mg) compared with placebo. The half-life of desglymidodrine was approximately 4 hours. CONCLUSION: A 10-mg dose of midodrine prescribed two to three times daily is effective in increasing orthostatic blood pressure and ameliorating symptoms in patients with NOH.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Midodrine increases BP both in the supine and upright posture and ameliorates symptoms of OH.

    “There is no doubt that midodrine increases BP both in the supine and upright posture, and ameliorates the symptoms of OH.”
  • Midodrine was shown to be effective in three randomized placebo-controlled trials.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
