Influence of prolonged exposure of a short half life non-steroidal anti-inflammatory drugs on gastrointestinal safety.

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
aimsTo test the influence of frequent concentration peaking, as occurs in multiple-dosing of non-steroidal anti-inflammatory drugs (NSAIDs) with short t (1/2), and duration of therapy of NSAIDs on gastrointestinal permeability. METHODOLOGY: 2.5 mg/(kg 12 h) flurbiprofen was administered as repeated oral and interperitoneal (i.p) doses or as i.p. osmotic pump (once implanted to mimic long t(1/2)) for 7 days to healthy rats. Urinary excretion of (51)Cr-EDTA (days 0, 1, 4 and 7 during all regimens) and sucrose (days 0, 1 and 7 for i.p. doses) were measured as markers of gastroduodenal and intestinal permeability, respectively.
resultsBoth i.p. regimens elevated (51)Cr-EDTA permeability suggestive of a systemic effect. There was no significant difference between the i.p regimens in (51)Cr-EDTA permeability. The first day (51)Cr-EDTA permeability was significantly higher for the oral than for the i.p. doses suggestive of a topcal effect. The effect became less potent with time despite continuous dosing indicating adaptation for both topical and systemic effects. None of the i.p. regimen altered sucrose permeability.
conclusionNSAID's potency to increase permeability reduces with time despite continuous dosing. Topical effect following oral dosing, and not the frequent peaking differentiates regimens from each other in elevating (51)Cr-EDTA permeability. The repeated dosing rather than the magnitude of t(1/2) may influence the gut safety profile of NSAIDs.
