摘要
Blinatumomab causes a transient cytokine release at treatment start that can suppress CYP450 enzymes. Theophylline, a narrow therapeutic index CYP1A2 substrate, may accumulate and cause toxicity such as tachyarrhythmia, nausea or seizures.
用白話說明這項交互作用的意義
Blinatumomab and Theophylline can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Blinatumomab belongs to Oncology; Theophylline belongs to Respiratory.
為什麼會發生
Cytokine-mediated transient suppression of hepatic CYP450 enzymes (including CYP1A2) reduces theophylline clearance.
處置方式
Monitor theophylline serum levels and signs of toxicity during the first days of the first cycle and when restarting after an interruption. Reduce the theophylline dose if levels rise.
