Amprenavir (Agenerase)

What Is Amprenavir?

Amprenavir is a drug used as part of antiretroviral therapy (ART). It is also called Agenerase®. It was manufactured by GlaxoSmithKline.

Manufacture of amprenavir was discontinued in October 2007. It is being replaced by fosamprenavir (see Fact Sheet 448). Fosamprenavir is a pro-drug of amprenavir. This means that when fosamprenavir is taken, it is broken down to produce amprenavir.
