Interactions between your drugs

Moderate

topotecan copanlisib

Applies to: topotecan and copanlisib

MONITOR: The use of topotecan with other cytotoxic agents is likely to result in greater myelosuppression due to additive or synergistic pharmacologic effects. Severe neutropenia and neutropenic sepsis resulting in death were reported with topotecan and cisplatin.

MANAGEMENT: Caution is advised if topotecan is used with other cytotoxic agents. Dosage reductions may be required, and bone marrow function should be closely monitored. Patients should be advised to contact their physician if they develop signs and symptoms of myelosuppression such as pallor, dizziness, fatigue, lethargy, fainting, easy bruising or bleeding, or signs of infection such as fever, chills, sore throat, body aches, and other influenza-like symptoms.

Drug and food interactions

Moderate

copanlisib food

Applies to: copanlisib

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of copanlisib. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of copanlisib by certain compounds present in grapefruit. When a single 60 mg intravenous dose of copanlisib was administered to cancer patients in combination with the potent CYP450 3A4 and P-gp inhibitor, itraconazole (200 mg once daily for 10 days), mean copanlisib peak plasma concentration (Cmax) did not change but systemic exposure (AUC) increased by 53%. The interaction has not been studied with grapefruit juice. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Increased exposure to copanlisib may increase the risk of adverse effects such as nausea, vomiting, diarrhea, stomatitis, hyperglycemia, hypertension, noninfectious pneumonitis, cutaneous reactions (e.g., exfoliative dermatitis, maculopapular rash), anemia, neutropenia, thrombocytopenia, and infections.

MANAGEMENT: Patients should avoid the consumption of grapefruit and grapefruit juice during treatment with copanlisib.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
