Tipranavir (Aptivus) Uses, Side Effects and Dosage
What is Tipranavir (Aptivus)?
Tipranavir is an antiretroviral drug in the class of protease inhibitor. The tipranavir brand name is Aptivus, manufactured by Boehringer Ingelheim Pharmaceuticals. Aptivus should only be taken by patients who have demonstrated a resistance to other protease inhibitors due to past use of other anti-HIV drugs.
What is This Medication Used For?
Tipranavir is used in combination with other antiretroviral drugs to treat HIV in treatment-experienced patients. While there is no cure for HIV, this medication is a medication prescribed as part of antiretroviral therapy, or ART, to help slow the production of HIV in the body.
Tipranavir and other protease inhibitors are used to interfere with the enzyme protease, which contributes to the creation of new viruses by HIV-infected cells. By inhibiting the activity of protease, the drug slows down or stops the production of new viruses by HIV-infected cells.
How to Take It
Aptivus is taken in combination with other antiretroviral drugs of different classes, typically nucleoside analogues (‘nukes’) and/or non-nucleoside reverse transcriptase inhibitors (NNRTIs, or ‘non-nukes’).
It is typically taken in combination with ritonavir (Norvir) with food.
