Pyridostigmine in the management of orthostatic hypotension: a systematic review and meta-analysis.
Synthesis in Open heart, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCurrent pharmacological approaches for the treatment of orthostatic hypotension (OH) may detrimentally affect supine blood pressure (BP). This side effect is often unacceptable and limits the utility of medical management. Pyridostigmine has been proposed as a potential treatment alternative which may improve OH without worsening supine hypertension. This systematic review and meta-analysis aimed to evaluate the currently available data regarding the use of pyridostigmine in the treatment of all-cause OH.
methodsA systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, EMBASE, Cochrane and SCOPUS were searched for publications until 4 June 2024. A random-effects model was used for meta-analysis.
resultsThe search returned 715 results, of which 6 randomised controlled trials met the inclusion criteria. Several studies reported a statistically significant improvement in orthostatic BP following pyridostigmine administration. Two studies found that pyridostigmine had no effect on standing BP among patients with severe autonomic failure. One study suggested that combination therapy with atomoxetine may elicit a synergistic effect. In most studies, pyridostigmine had no significant effect on supine BP. Adverse effects were minimal across the included studies. The pooled results from the meta-analysis showed that while pyridostigmine alone resulted in lower systolic and diastolic orthostatic drop, neither result was statistically significant. However, when pyridostigmine is combined with midodrine, this demonstrated a significant improvement in systolic orthostatic drop.
conclusionsPyridostigmine may be useful in the management of OH, particularly in patients with supine hypertension. The standing BP response to pyridostigmine may be greater in patients who have a relatively preserved baroreflex function and sympathetic reserve. PROSPERO REGISTRATION NUMBER: CRD42024555402.
