Pfizer Inc. has announced that it has received European Commission approval for its AIDS drug Celsentri. The drug, generically known as Maraviroc is the first in a class of oral HIV medicine in more than 10 years.
Celsentri, discovered and developed by Pfizer UK blocks viral entry of the HIV virus into the white blood cells. IT will be made available to HIV patients in the EU in combination with other antiretroviral medications. Maraviroc prevents the virus from entering white blood cells by blocking its main entry route, the CCR5 co-receptor rather than fighting HIV inside the white blood cells.
Maraviroc, known as Selzentry in the United States, was approved by the U.S. Food and Drug Administration (FDA) on August 6, 2007 and is currently available in the U.S.
