Urapidil as a neuroprotective agent: targeting hypoxia, inflammation, and oxidative stress in traumatic brain injury.
Article in European journal of trauma and emergency surgery : official publication of the European Trauma Society, 2025. 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
purposeOne of the important causes of morbidity and mortality in the world is traumatic brain injury (TBI), which is a process that triggers damaging mechanisms such as inflammation, oxidative stress, and apoptosis. The results of current pharmaceutical methods are not enough, and researches into new therapy modalities are needed. This study aimed to evaluate the neuroprotective effects of Urapidil (Ura), which is an alpha-1 adrenergic receptor antagonist with serotonergic activity, in a TBI model and investigating signaling pathways like high mobility group box 1 (HMGB1), BCL2-interacting protein 3-like (BNIP3L), and hypoxia-inducible factor-1 alpha (HIF1α).
methodsThirty-two rats were divided into four groups: control, TBI, TBI + Ura
resultsUra treatment at both doses, significantly decreased histopathological findings, BNIP3L, HMGB1, and HIF1α expressions, TNF-α, Cas-3, TH immunexpressions, and TOS and OSI levels, and elevated TAS levels compared to TBI group. These results show that Ura regulates molecular pathways related to TBI, including neuroinflammation, mitochondrial dysfunction, and hypoxia.
conclusionUra shows promising tissue-protective effects in TBI by targeting inflammation, oxidative stress, and apoptosis. This study provides a new perspective on the need for further development of Ura for therapeutic use.
