Drug class: Integrase Inhibitors
Raltegravir, also known as Isentress and MK-0518, is a type of medicine called an integrase inhibitor. Integrase inhibitors work by blocking integrase, a protein that HIV needs to insert its viral genetic material into the genetic material of an infected cell.
HIV/AIDS-Related Uses
Raltegravir was approved by the FDA on October 12, 2007, for use with other anti-HIV agents in the treatment of HIV infection in adults. It is the first integrase inhibitor approved by the FDA. This medicine does not cure or prevent HIV infection or AIDS and does not reduce the risk of passing the virus to other people.
In August 2006, Merck opened a worldwide expanded access program for individuals with HIV who have limited or no treatment options. Individuals and health care professionals can call 1-888-577-8839 or visit www.earmrk.com for more information.
