Sintesi
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.
Cosa significa questa interazione in parole semplici
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.
Perché avviene
Cytokine-mediated transient suppression of hepatic CYP450 enzymes (including CYP1A2) reduces theophylline clearance.
Cosa fare
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.
