Effects of Dimenhydrinate on Motor Behavior and Vascular Function: Possible Implications for the Field of Sports.
Article in Drug testing and analysis, 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
Several studies have described the sedative effects of dimenhydrinate (DMH), although others report a stimulant effect on psychomotor functions. Because the first generation of antihistamines was shown to seriously impair cognitive psychomotor and driving performance in healthy volunteers, the aim of our research was to determine the effect of DMH by testing physical activity and cognitive and cardiovascular functions using an animal model to identify a possible stimulatory effect. The study protocol consisted of two phases. The first was designed to analyze the stimulating motor effect of DMH. Four study groups were formed: (1) vehicle (Veh), (2) modafinil (MOD), (3) DMH at 50 mg/kg (DMH-50), and (4) DMH at 200 mg/kg (DMH-200). Motor coordination and balance, physical activity, hemodynamics, and nitrous oxide (NO) quantification were performed. In the second phase, we sought to discriminate the compound in DMH that generates the stimulating effect. In this case, the study groups were (1) Veh, (2) MOD, (3) DMH, (4) diphenhydramine (DPH), (5) 8-chlorotheophylline (8-Cl-T), and (6) theophylline (TEO). In this phase, we quantified glucose and insulin levels, behavior, physical activity, blood pressure, and vascular reactivity to phenylephrine and acetylcholine. Findings showed that DMH might improve a motor and physical stimulating effect but also increased NO levels in the lungs. DPH promoted a compulsive-like behavior that diminished with 8-Cl-T. Regarding cardiovascular effects, DMH decreased vascular reactivity to phenylephrine and acetylcholine. Finally, in the DMH formulation, 8-Cl-T was identified as the compound responsible for increasing blood pressure and heart rate.
