摘要
Trastuzumab can cause left ventricular dysfunction and heart failure, and the risk is greatest when it is given with or soon after anthracyclines. Liposomal doxorubicin is less cardiotoxic than conventional doxorubicin but still adds cardiac risk.
用白話說明這項交互作用的意義
Doxorubicin liposomal and Trastuzumab can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
為什麼會發生
Additive cardiotoxicity: anthracycline myocyte injury combined with impaired HER2-dependent cardiomyocyte repair from trastuzumab.
處置方式
Avoid the combination if possible. If it is used, assess left ventricular ejection fraction before and at regular intervals during treatment, and stop trastuzumab for significant decline.
