Severe Impact of Omeprazole Timing on pH-Sensitive Dasatinib Absorption: Unveiling Substantial Drug-Drug Interaction.
Article in Journal of clinical pharmacology, 2025. 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
The absorption and bioavailability of most tyrosine kinase inhibitors are affected by gastrointestinal pH as they are weak basic lipophilic drugs. Hence, concomitant use of acid reducing agents (ARAs) is frequently restricted. Particularly comedication of crystalline dasatinib (Sprycel) and proton-pump inhibitors (PPIs) should be avoided. Drug-drug interaction (DDI) studies with PPIs report approximately 40%-80% bioavailability reduction of dasatinib. Limitations in the design of these studies do not allow for assessing the near maximum DDI as timing of PPI dosing was either not reported or 22 h prior to dasatinib intake. We conducted a DDI study of crystalline dasatinib and omeprazole in healthy, fasted participants, investigating the impact of PPI comedication on dasatinib plasma exposure at a time point when the near maximum DDI effect is expected. Participants were administered omeprazole (day 2-5) to reach steady state. On day 6, a single dose of crystalline dasatinib was given. Crystalline dasatinib dosing alone on day 1 served as control (single dose). The dosing interval between omeprazole administration and crystalline dasatinib was 10 h (median [range: 9-10 h]).
