Raltegravir, also known as raltegravir potassium and RAL, typically is a medicine widely used as part of antiretroviral therapy (ART). It was approved by the FDA in 2007 as an ARV (antiretroviral) medicine for individuals with HIV infection. Raltegravir comes as tablets under the brand name Isentress and is manufactured by Merck & Co., Inc.
Raltegravir tablet is a type of drug named an integrase inhibitor. Integrase inhibitors inhibit integrase (an HIV enzyme). HIV uses integrase in order to insert (integrate) its viral DNA into the DNA of host CD4 cells. Inhibiting the integrase prevents HIV from replicating.
When used in combination with other antiretrovirals to treat HIV infection, raltegravir may help:
Reduce the level of HIV in the blood. This is called viral load.
Increase the number of CD4 cells in the blood that help fight off other infections.
Reducing the level of HIV and increasing the CD4 cells in your blood may help enhance your immune system. This may reduce the probability of death or catching opportunistic infections (OIs) that may happen when your immune system is not strong.
Raltegravir treatment does not cure HIV infection or AIDS. You must keep taking your HIV medications in order to control HIV infection and decrease HIV-related illnesses.
How is Raltegravir Supplied
The raltegravir 400 mg is typically supplied in two forms: Isentress and Isentress HD.
Isentress: Isentress is a prescription HIV drug approved to be used along with other ARVs for the treatment of HIV infection in adults and children who weigh at least 2 kg (4.4 pounds). The safety, as well as the effectiveness of this medicine, has not been established in children who weigh below 2 kg (4.4 pounds).
Isentress HD: Isentress HD is a prescription HIV drug that is approved to be used along with other ARVs for the treatment of HIV infection in adults and children who weigh at least 40 kg (88 pounds) who have not taken any ARVs earlier or whose virus has been suppressed on an initial regimen of Isentress.
All the patients living with HIV should be on antiretroviral therapy to keep healthy and not transmit the virus to others. You and your health specialist should consider your CD4 cell count, your viral load, any signs/symptoms you are having, and your preferences when choosing which existing HIV medicines are appropriate for you.

How Does Raltegravir Work?
Raltegravir is specifically an antiretroviral that inhibits the replication of HIV (human immunodeficiency virus). It falls under the group of medications named integrase inhibitors. The raltegravir 400 mg tablet is used as soon as possible just after exposure to HIV in order to prevent the progression of the virus through your system and therefore help fight infection.
