Ticagrelor Steady-State Trough Concentration in Chinese Patients Undergoing Percutaneous Coronary Intervention.
Article in European journal of drug metabolism and pharmacokinetics, 2024. 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
BACKGROUND AND
objectivePlatelets play a pivotal role in thrombotic events associated with acute coronary syndrome (ACS), making oral antiplatelet therapy a cornerstone in antithrombotic strategies. The dosing regimen for the oral antiplatelet drug ticagrelor warrants evaluation to ensure its appropriateness in clinical practice. Therefore, this study aimed to investigate the real-world clinical application of ticagrelor by determining the optimal therapeutic concentration of ticagrelor in Chinese patients undergoing percutaneous coronary intervention (PCI).
methodsWe enrolled a cohort of 912 patients who underwent PCI with drug-eluting stent implantation for the treatment of ACS. We measured steady-state plasma drug concentrations using high-performance liquid chromatography-tandem mass spectrometry. The therapeutic drug concentration range at steady state was established on the basis of clinical pharmacodynamic indices, with verification of reliability through concentration-effect analysis and receiver operating characteristic curve assessment.
resultsAnalysis of plasma samples from the 912 patients revealed significant variations in the steady-state trough concentration of ticagrelor associated with factors such as gender, age, hypertension, and hyperlipidemia. On the basis of this analysis, the optimal therapeutic range for steady-state trough concentration was determined to be 240.65-335.83 ng/mL. Furthermore, the upper limit values for steady-state concentration were established at 439.97 ng/mL for male patients and 347.06 ng/mL for female patients.
conclusionsThis study provides robust and reliable insights into the optimal therapeutic steady-state trough concentrations of ticagrelor in Chinese patients with post-percutaneous coronary intervention. These findings have significant implications for guiding the rational use of antiplatelet drugs and facilitating precise drug administration in Chinese patients undergoing percutaneous coronary intervention.
