Salvage therapy

Salvage therapy, also known as rescue therapy, is a form of treatment given after an ailment does not respond to standard treatment. The most common diseases that require salvage therapy are HIV and various tumors. The word is not clearly defined; it is used both to mean a second attempt and a final attempt. Salvage therapy drugs or drug combinations have, in general, much more severe side effects than the standard line of therapy.

HIV
Antiretroviral drugs (ARVs) are given to slow down the HIV reproduction, which in turn increases quality of life and survival. If the patient's viral load starts to increase instead of staying very low, it almost always means the virus has developed a resistance to the ARVs. As more and more mutations develop, it becomes harder to select an ARV that will contain it. Salvage therapy is the attempt to contain it, even though there are no common options. One definition in HIV therapy speaks of salvage therapy when at least one regimen containing protease inhibitors has failed in a patient. .
