A cross-sectional observational study of the prevalence and characterization of potential QT-prolonging drug‒drug interactions in oncological outpatients.
Objectives: This study aims to assess the prevalence, characteristics, and risk factors of potential QT-prolonging drug-drug interactions (pQT-DDIs) in cancer patients, including identifying drug combinations contributing to QT prolongation and key predictors.
Methods: In this hospital-based, cross-sectional observational study, all types of cancer patients, irrespective of age or sex, were included over 1 year. pQT-DDIs were identified using four drug interaction checker software tools. Predictors were analyzed using univariate logistic regression.
Results: A total of 1,331 cancer patients were included. The prevalence of pQT-DDIs was 67.6 %. Of these, 606 (45.5 %) had 1-2 pQT-DDIs, 126 (9.5 %) had 3-4, and 78 (5.9 %) had 5-6. Overall, 163 drug combinations were identified as causing QT prolongation; 122 were detected by Drugs.com. Significant predictors included >8 drugs prescribed (OR=6.46; CI=4.87-8.56; p<0.0001), >2 anticancer drugs (OR=1.68; CI=1.14-2.46; p=0.008), >6 adjuvant drugs (OR=6.83; CI=5.17-9.03; p<0.0001), solid cancers (OR=6.59; CI=4.59-8.80; p<0.0001), and cytotoxic drug use (OR=2.40; CI=1.52-3.77; p=0.0001).
Conclusions: There is a high prevalence of pQT-DDIs in cancer patients. Those receiving multiple anticancer and adjuvant drugs are at higher risk. Routine interaction screening is recommended before chemotherapy.
期刊介绍：
The Journal of Basic and Clinical Physiology and Pharmacology (JBCPP) is a peer-reviewed bi-monthly published journal in experimental medicine. JBCPP publishes novel research in the physiological and pharmacological sciences, including brain research; cardiovascular-pulmonary interactions; exercise; thermal control; haematology; immune response; inflammation; metabolism; oxidative stress; and phytotherapy. As the borders between physiology, pharmacology and biochemistry become increasingly blurred, we also welcome papers using cutting-edge techniques in cellular and/or molecular biology to link descriptive or behavioral studies with cellular and molecular mechanisms underlying the integrative processes. Topics: Behavior and Neuroprotection, Reproduction, Genotoxicity and Cytotoxicity, Vascular Conditions, Cardiovascular Function, Cardiovascular-Pulmonary Interactions, Oxidative Stress, Metabolism, Immune Response, Hematological Profile, Inflammation, Infection, Phytotherapy.
