Darunavir, usually boosted with ritonavir or cobicistat, strongly inhibits CYP3A4 and can markedly raise dronedarone concentrations. This increases risk of serious arrhythmia.
What this interaction means in plain words
Darunavir and Dronedarone are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Darunavir belongs to Anti Virals; Dronedarone belongs to Cardiovascular.
Why it happens
Inhibition of CYP3A4 metabolism of dronedarone by the boosted protease inhibitor.
What to do
Do not coadminister; choose a different rhythm-control strategy.
