Summary
Tipranavir is given with ritonavir, which strongly inhibits CYP3A4, and can raise flibanserin levels. Severe hypotension, syncope and sedation may result.
What this interaction means in plain words
Flibanserin and Tipranavir 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.

Why it happens
Ritonavir-boosted inhibition of CYP3A4 reduces flibanserin clearance.
