Tipranavir is primarily used in the treatment of HIV-1 infection, particularly in patients who have developed resistance to other protease inhibitors. It is often prescribed in combination with ritonavir, which boosts its effectiveness by increasing its concentration in the bloodstream. This combination therapy helps to reduce the viral load in patients, improving their immune function and slowing the progression of the disease. Tipranavir is especially valuable for individuals who have limited treatment options due to multidrug-resistant HIV strains. Its use is carefully monitored due to potential side effects, including liver toxicity and increased risk of bleeding.
