Tyrosine kinase inhibitors (TKIs) are frequently used drugs in oncology practice. Although oral administration is an advantage, long-term use increases potential drug-drug interaction risk. The purpose of this study was to assess the prevalence of potential TKI-drug interaction (PTDI) in patients who used TKIs and increase awareness of this subject.We retrospectively evaluated the data of 310 patients collected from four different oncology centers, where TKIs were administered for solid organ cancer, between January 2007 and December 2017. The potential interaction between TKI and any other prescribed drug was determined using ''Lexicomp® Drug Interactions, App Version 1.1'' software.Overall, 310 patients were included; among those, 301 (97.1%) were using another drug with TKI and 147 (47.4%) experienced PTDI at least once. The median number of additional drugs was 4 (range 1-12). We detected 250 PTDIs, of which 30.8% were major interactions. The most frequently interacting TKI was imatinib (29.6%), and the additional drug group was antibiotics (21.2%). We observed that PTDIs caused the following effects: TKI concentration was increased or decreased owing to 14.4% or 22.8% PTDIs, respectively, and electrocardiographic QT prolongation occurred in 22% of all PTDIs. Multivariate analysis demonstrated that use of higher number of additional drugs (odds ratio/OR=1.63), pre-existing lung cancer (OR=8.82), and use of pazopanib (OR=9.22) were potential risk factors.The rate of PTDI is quite high in patients using TKIs. Effort must be made to increase awareness of this subject. Increasing awareness aids in lowering toxicity rates and providing efficient antitumor therapy. |
