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.

The most frequently reported adverse drug reactions were-

  • diarrhea
  • nausea
  • vomiting
  • abdominal pain 
  • fever
  • headache
  • fatigue/asthenia
  • 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.

 

Contraindication

Tipranavir is contraindicated in-

  • patients with moderate or severe (Child-Pugh Class B or C) hepatic impairment.
