Tipranavir
Tipranavir is an antiviral drug from the class protease inhibitor. The HIV-1 protease is inhibited by the peptidomimetic drug ritonavir. HIV protease inhibition prevents the enzyme from processing the Gag-Pol polyprotein precursor, which results in the generation of immature, non-infectious HIV particles.
Tipranavir is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection.
- Adults: 500 mg Tipranavir, co-administered with 200 mg ritonavir, twice daily.
- Pediatric patients (age 2 to 18 years): Dosing is based on body weight or body surface area not to exceed adult dose.
- Tipranavir taken with ritonavir capsules or solution can be taken with or without meals.
- Tipranavir taken with ritonavir tablets must be taken with meals.
- Store unopened bottles of Tipranavir capsules in the refrigerator.
- Do not freeze or refrigerate Tipranavir oral solution.
- Discontinue if you have clinical hepatitis or asymptomatic increases in ALT/AST >10 times the upper limit of normal or asymptomatic increases in ALT/AST 5-10 times the upper limit of normal with concomitant increases in total bilirubin. Prior to starting therapy, and on a regular basis afterwards, have liver function tests performed.
- Use with caution in patients who are at high risk of bleeding or who are taking medications that increase the risk of bleeding.
- Consider the potential for drug-drug interactions to reduce the risk of serious or life-threatening adverse reactions.
- If a severe skin reaction occurs or is suspected, discontinue and begin appropriate treatment. In patients who have a known sulfonamide allergy, use with caution.
- Diabetes mellitus, hyperglycemia, immune reconstitution syndrome, redistribution/accumulation of body fat, and elevated lipids may occur in patients. Monitor cholesterol and triglycerides prior to therapy and periodically thereafter.
- Spontaneous bleeding may occur, and additional factor VIII may be required.
