Effects of dosing interval on the pharmacokinetic and pharmacodynamic interactions between the oral adsorbent AST-120 and triazolam in humans.
Trial report in European journal of clinical pharmacology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThe objective of this study was to evaluate the pharmacokinetic and pharmacodynamic interactions between the oral adsorbent AST-120 and triazolam.
methodsIn this randomized, cross-over study, 12 healthy volunteers received a single oral dose of triazolam 0.25 mg alone or with AST-120 2 g given 0, 30 or 60 min before triazolam administration.
resultsThe area under the plasma triazolam concentration-time curve (AUC(0-∞)) significantly decreased with simultaneous AST-120 + triazolam (alone vs simultaneous: 10.9 ± 6.0 vs 6.4 ± 2.6 ng·h/mL, p = 0.003). Triazolam-induced impairment in psychomotor performance assessed by the digit symbol substitution test was significantly attenuated when AST-120 was administered simultaneously. No significant changes in pharmacokinetic and pharmacodynamic parameters were observed when AST-120 was given 30 or 60 min before triazolam administration.
conclusionsAdministering AST-120 simultaneously with triazolam affects the pharmacokinetics and pharmacodynamics of triazolam. Dosing AST-120 at least 30 min before triazolam administration may avoid these interactions.
