Abstract
Background: Dasatinib has been widely used in the treatment of a variety of cancers, such as lung cancer and acute myeloid leukemia. Shenmai injection is a traditional Chinese medicine injection that is often used in antitumor adjuvant therapy. In recent years, dasatinib combined with Shenmai injection has been increasingly used to treat tumors clinically. However, the potential risks and benefits of co-administering Shenmai injection and dasatinib are unclear.
Objective: The study aimed to investigate the potential influence of Shenmai injection on dasatinib pharmacokinetics.
Methods: Twelve rats were selected and randomly divided into two groups: dasatinib alone and a combination of dasatinib and Shenmai injection. To measure the concentration of dasatinib in rat plasma, blood samples were obtained from the orbital vein. Using ultra-performance liquid chromatography-tandem mass spectrometry, the concentration of dasatinib was determined to obtain pharmacokinetic parameters.
Results: Compared to the dasatinib alone administration, the maximum concentration of the dasatinib plus Shenmai injection administration was decreased (355.9 ± 194.9 vs. 199.2 ± 73.8 ng·mL-1) (P < 0.05). Moreover, the area under the moment curve (3867.0 ± 2141.9 vs. 6355.3 ± 3311.6 ng·mL-1·h2) and mean residence time (3.7 ± 1.2 vs. 6.5 ± 3.1 h) showed a statistically significant increase (P < 0.05).
Conclusion: The study revealed that Shenmai injection might have the capacity to slow down the absorption rate of dasatinib and could extend the retention period of dasatinib in the body, resulting in stabilized blood drug concentrations and a reduction in adverse drug reactions.
期刊介绍：
Current Drug Metabolism aims to cover all the latest and outstanding developments in drug metabolism, pharmacokinetics, and drug disposition. The journal serves as an international forum for the publication of full-length/mini review, research articles and guest edited issues in drug metabolism. Current Drug Metabolism is an essential journal for academic, clinical, government and pharmaceutical scientists who wish to be kept informed and up-to-date with the most important developments. The journal covers the following general topic areas: pharmaceutics, pharmacokinetics, toxicology, and most importantly drug metabolism.
More specifically, in vitro and in vivo drug metabolism of phase I and phase II enzymes or metabolic pathways; drug-drug interactions and enzyme kinetics; pharmacokinetics, pharmacokinetic-pharmacodynamic modeling, and toxicokinetics; interspecies differences in metabolism or pharmacokinetics, species scaling and extrapolations; drug transporters; target organ toxicity and interindividual variability in drug exposure-response; extrahepatic metabolism; bioactivation, reactive metabolites, and developments for the identification of drug metabolites. Preclinical and clinical reviews describing the drug metabolism and pharmacokinetics of marketed drugs or drug classes.
