Uses For tipranavir
Tipranavir is used in combination with ritonavir (Norvir®) to treat an infection caused by the human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS). tipranavir is usually given to patients who have received HIV treatment in the past.
Tipranavir will not cure or prevent HIV infection or AIDS. It helps keep HIV from reproducing and appears to slow down the destruction of the immune system.

People who receive tipranavir may continue to have the problems usually related to AIDS or HIV disease.
