Abstract:

Tyrosine kinase inhibitors (TKIs) are typically used as novel anti-tumor drugs, which have been widely applied to clinical treatments in recent years. Clinical trials have demonstrated that these drugs are effective in the treatment of various cancers. TKIs have also been reported to affect the QT interval, but the effects are not the same in different drug treatments. Therefore, each TKI has different warnings,precautions, and monitoring indicator. Some of TKIs can cause severe QT interval prolongation and even sudden death, so we need to adjust the dose according to the individual patient's QT interval. In this paper, we reviewed the related literature and the FDA drug instructions, and analyzed the clinical trials focusing the effects of listed TKIs on QT interval and dosage adjustment. The risks of such drugs have been better understood via the summary of the previous experimental results, and it would play a guiding role to TKIs clinical treatments.

Key words: interval prolong, tyrosine kinase inhibitors, heart rate corrected QT interval, drug safety
