Summary
Tipranavir, given with ritonavir, inhibits CYP3A4 and can increase axitinib exposure. This raises the risk of axitinib toxicity, although tipranavir also has inducing properties that make net effects less predictable.
What this interaction means in plain words
Axitinib and Tipranavir 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.
Axitinib belongs to Oncology; Tipranavir belongs to Anti Virals.
Why it happens
Ritonavir-boosted tipranavir inhibits CYP3A4-mediated axitinib metabolism.
What to do
Use an alternative antiretroviral if possible. If coadministered, reduce axitinib dose by about 50% and monitor for toxicity.
