Brand name: Lexiva
Active Ingeridents:Fosamprenavir Calcium
Company Name: Glaxosmithkline
Package: 60 Tablets
Mechanism of action:
Lexiva (FOSAMPRENAVIR CALCIUM) is a prodrug that is rapidly hydrolyzed to amprenavir by cellular phosphatases in the gut epithelium as it is absorbed. Amprenavir is an inhibitor of HIV-1 protease. During HIV replication, HIV protease cleaves viral polypeptide products of the Gag and Gag-Pol genes to form structural proteins of the virion core and essential viral enzymes. Amprenavir interferes with this process by binding to the active site of HIV-1 protease, thereby preventing the processing of viral Gag and Gag-Pol polyprotein precursors, resulting in the formation of immature non-infectious viral particles.
