Drugs taken for cancer can interact with each other, with agents taken as part of supportive care, with drugs taken for comorbid conditions (which are particularly common in the elderly patients), and with herbal supplements and complementary medicines. We tend to focus on the narrow therapeutic window of cytotoxics, but the metabolism of tyrosine kinase inhibitors by the cytochrome P450 3A4 enzyme (CYP3A4) makes some TKIs particularly prone to interference with or from other agents sharing this pathway. There is also potential for adverse pharmacokinetic interactions with new hormonal agents used in advanced prostate cancer.
用于治疗癌症的药物可能会相互作用,也会与作为支持性治疗一部分使用的药物、用于治疗合并症(在老年患者中尤为常见)的药物以及草药补充剂和辅助药物发生相互作用。我们往往将重点放在细胞毒性药物狭窄的治疗窗上,但细胞色素P450 3A4酶(CYP3A4)对酪氨酸激酶抑制剂的代谢使得一些酪氨酸激酶抑制剂特别容易受到共享该途径的其他药物的干扰或对其产生干扰。晚期前列腺癌中使用的新型激素药物也存在不良药代动力学相互作用的可能性。
