Summary
Lopinavir, boosted with ritonavir, strongly inhibits CYP3A4 and can substantially raise nilotinib concentrations. Both drugs can prolong the QT interval, so the arrhythmia risk is increased.
What this interaction means in plain words
Lopinavir and Nilotinib 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.
Lopinavir belongs to Anti Virals; Nilotinib belongs to Oncology.
Why it happens
CYP3A4 inhibition by lopinavir/ritonavir reduces nilotinib clearance, with additive QT effects.
What to do
Avoid the combination if possible. If necessary, reduce the nilotinib dose per labeling for strong CYP3A4 inhibitors and monitor ECG and electrolytes.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
