Consumer:Talk to your doctor before using tipranavir together with dolutegravir. Combining these medications may reduce the blood levels of dolutegravir, which may make the medication less effective in treating HIV infection. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition worsens or you develop new infections during treatment with these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:ADJUST DOSE: Coadministration with potent inducers of UGT1A3 and CYP450 3A4 isoenzymes such as tipranavir/ritonavir may significantly decrease the plasma concentrations of dolutegravir, which is primarily metabolized by UGT1A1 with some contribution from CYP450 3A4. Dolutegravir is also a substrate of UGT1A3, UGT1A9, and P-glycoprotein in vitro. In 14 study subjects, administration of dolutegravir 50 mg once daily with tipranavir/ritonavir 500 mg/200 mg twice daily decreased dolutegravir peak plasma concentration (Cmax), systemic exposure (AUC) and trough plasma concentration (Cmin; 24 hours postdose) by 46%, 59% and 76%, respectively, compared to administration without tipranavir/ritonavir.
MANAGEMENT: When prescribed in combination with tipranavir/ritonavir, the dosage of dolutegravir should be increased to 50 mg twice daily for both adults and pediatric patients 12 years of age and older who weigh at least 40 kg. The safety and efficacy of dosages above 50 mg twice daily have not been evaluated. Concomitant use of tipranavir/ritonavir with the fixed-dose combination product containing dolutegravir/lamivudine is not recommended. For concomitant use of tipranavir/ritonavir with the fixed-dose combination product containing abacavir/dolutegravir/lamivudine, it is recommended to administer an additional dose of dolutegravir 50 mg/day, separated from the combination product by 12 hours. Alternative treatment combinations that do not include metabolic inducers should be considered whenever possible for integrase strand transfer inhibitor (INSTI)-experienced patients with certain INSTI-associated resistance substitutions or clinically suspected INSTI resistance.
