Fexuprazan for upper gastrointestinal protection in patients with ischemic stroke and gastroesophageal reflux disease (GERD) receiving antithrombotic therapy: A preliminary prospective single-arm observational Study.
Observational study in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundProton pump inhibitors are standard for preventing upper gastrointestinal (UGI) complications in patients receiving antithrombotic therapy, but their limitations highlight the need for alternatives. Potassium-competitive acid blockers (P-CABs), such as fexuprazan, are emerging substitutes, yet evidence supporting their protective role in this setting remains limited. This study aimed to evaluate the effect of fexuprazan in patients with acute ischemic stroke (AIS) and gastroesophageal reflux disease (GERD) receiving antithrombotic therapy.
methodsThis prospective, single-center, single-arm study included consecutive patients with AIS and GERD who were receiving antithrombotic therapy and treated with fexuprazan between June 2023 and March 2025. At the study hospital, all admitted AIS patients were systematically screened for GERD using the Gastroesophageal Reflux Disease Questionnaire (GerdQ), with a score ≥8 indicating GERD. The primary outcome was the change in GerdQ score from baseline to 12 weeks after the index AIS. Safety outcomes included recurrent stroke or serious adverse events within 12 weeks. The secondary efficacy outcome was the occurrence of a composite of UGI clinical events.
resultsAmong 623 patients with AIS screened during the study period, 18 patients with GERD receiving antithrombotic therapy and treated with fexuprazan were enrolled and followed for 12 weeks. The mean age was 65.6 years, and 9 patients (50.0%) were male. The mean GerdQ score significantly improved from 8.8 ± 2.3 at baseline to 6.6 ± 1.7 at 12 weeks (P = 0.003). A normal GerdQ score (<8) was achieved in 88.9% of the patients. One patient (5.6%) experienced a UGI clinical event and one had a recurrent transient ischemic attack.
conclusionsThis preliminary prospective single-arm study using a structured symptom-based assessment suggests that fexuprazan may be associated with symptom relief in patients with AIS and GERD receiving antithrombotic therapy. However, due to the small sample size and lack of a control group, these findings should be interpreted as hypothesis-generating and warrant further confirmation in larger, controlled trials.
