Itraconazole and domperidone: a placebo-controlled drug interaction study.
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 4 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
purposeTo determine the influence of itraconazole on the pharmacokinetics, and the CNS and prolactin-elevating effects of domperidone in humans.
methodsFifteen healthy volunteers received either itraconazole (200 mg daily) or placebo for 5 days with a double blind, randomized, cross-over design. A single oral 20-mg dose of domperidone was administered to subjects on day 5. Plasma domperidone and serum prolactin concentrations were measured. The effects of domperidone on CNS were also assessed using self-rating scales and electroencephalography.
resultsItraconazole significantly increased domperidone AUC(0-∞) (3.2-fold) and C(max) (2.7-fold) compared with placebo, but had no significant effect on the elimination half-life of domperidone. The CNS effects of domperidone assessed by self-rating of mood and electroencephalography, and the prolactin-elevating effect, were not significantly affected by itraconazole. A counterclockwise hysteresis was evident in the relationship between plasma domperidone and serum prolactin concentrations. Itraconazole shifted the hysteresis to the right. Concentration-effect modeling procedures yielded a significant linear relationship between hypothetical effect site domperidone concentrations and prolactin levels. Itraconazole reduced the slope of the linear relationship.
conclusionsItraconazole significantly increased plasma domperidone concentrations. The interaction is probably mainly due to a reduced first pass elimination by inhibition of CYP3A and/or MDR1. The clinical significance of the altered relationship between domperidone concentrations and prolactin levels caused by itraconazole is still to be determined.
