Histamine H2-receptor antagonists have no clinically significant effect on the steady-state pharmacokinetics of voriconazole.
Trial report in British journal of clinical pharmacology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled it.
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
aimsVoriconazole, a new triazole antifungal agent, is metabolized mainly by cytochrome P450s CYP2C19 and CYP2C9, and also by CYP3A4. The aim of this open-label, placebo-controlled, randomized, three-way crossover study was to determine the effects of cimetidine and ranitidine on the steady-state pharmacokinetics of voriconazole.
methodsTwelve healthy male subjects received oral voriconazole 200 mg twice daily plus cimetidine 400 mg twice daily, voriconazole 200 mg twice daily plus ranitidine 150 mg twice daily, and voriconazole 200 mg twice daily plus placebo twice daily. Treatment periods were separated by at least 7 days.
resultsWhen cimetidine was administered with voriconazole, the maximum plasma voriconazole concentration (Cmax) and the area under the plasma concentration-time curve of voriconazole (AUCtau) was increased by 18.3%[90% confidence interval (CI) 6.0, 32.0] and 22.5% (90% CI 13.3, 32.5), respectively. Concomitant ranitidine had no significant effect on voriconazole Cmax or AUCtau. Time of Cmax (tmax) elimination half-life (t 1/2) or terminal phase rate constant (kel) for voriconazole were similar in all three treatment groups. Most adverse events were mild and transitory; two subjects were withdrawn due to adverse events.
conclusionsCoadministration of the histamine H2-receptor antagonists cimetidine or ranitidine does not affect the steady-state pharmacokinetics of voriconazole in a clinically relevant manner.
