Aptivus (Tipranavir Oral Solution) and Oystercal-D

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Using calcium carbonate together with tipranavir can decrease the effects of tipranavir. You should be separate tipranavir from calcium carbonate administration to prevent this interaction. Contact your doctor if your condition worsens. You may need a dose adjustment or special test to safely use both 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.

ADJUST DOSING INTERVAL: Concurrent administration of antacids or other agents with acid-neutralizing effects may decrease the oral bioavailability of tipranavir and reduce its concentrations in plasma. The mechanism of interaction has not been described. When tipranavir (in combination with low-dose ritonavir) was coadministered with 20 mL of an aluminum- and magnesium-based liquid antacid, tipranavir peak plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC) were reduced by 25% to 29%. The clinical significance of these changes is unknown. However, subtherapeutic antiretroviral drug levels may lead to reduced viral susceptibility and development of resistance.

MANAGEMENT: Consideration should be given to separating tipranavir/ritonavir dosing from antacid administration to prevent reduced absorption of tipranavir.
