check viral levels and if possible tipranavir levels.
In vitro metabolism studies with human liver microsomes indicated that CYP3A4 is the predominant CYP isoform involved in tipranavir metabolism.
The potential net effect of tipranavir/ ritonavir on CYP 2D6 is inhibition,
Liver impairment could therefore result in an increase of tipranavir exposure and a worsening of its safety profile.
medicinal products that inhibit Pgp may increase tipranavir plasma concentrations.
Nevertheless, the clinical data available from the RESIST trials did not suggest any significant alteration of the tipranavir/ ritonavir safety profile when combined with enfuvirtide as compared to patients treated with tipranavir/ ritonavir without enfuvirtide.
ml of aluminium- and magnesium-based liquid antacid, tipranavir AUC12h, Cmax
Clinical isolates that exhibited a≥ 10-fold decrease in tipranavir susceptibility harboured eight or more tipranavir-associated mutations.
Studies with co-administration of tipranavir and ritonavir did not reveal any additional toxicological effects when compared to those seen in the tipranavir single agent toxicological studies.
Dosage adjustment is only recommended in patients with renal impairment who are receiving potent CYP3A4 inhibitors such as:• protease inhibitors(except tipranavir/ ritonavir)• ketoconazole, itraconazole, clarithromycin, telithromycin.
protease inhibitors except for tipranavir/ ritonavir.
Tipranavir resistant viruses which emerge in vitro from wild-type HIV-1 show decreased susceptibility to the protease inhibitors amprenavir,
16 amino acids have been associated with reduced tipranavir susceptibility and/
Interactions with medicinal products It is not recommended to combine etravirine with tipranavir/ ritonavir, due to a marked pharmacokinetic
no clinically important changes in tipranavir/ ritonavir plasma concentrations were observed and thus no tipranavir/ ritonavir dose adjustment is required.
Tipranavir AUC over a 12 hour dosing interval averaged 851± 309 µM• h(CL=1.15 l/ h)
did not significantly alter tipranavir AUC and Cmax
By contrast, evaluation of the steady-state plasma tipranavir trough concentrations at 10-14 h after dosing from the RESIST-1 and RESIST-2 studies demonstrate that females generally had higher tipranavir concentrations than males.
III trials treated with the 500 mg/ 200 mg tipranavir/ ritonavir dose(n=1397) are listed below
saquinavir( three of 24 isolates) and tipranavir/ ritonavir four of 24 isolates.
