Groups	approved investigational
Description	Saquinavir is an HIV-1 protease inhibitor used in combination with [ritonavir] and other antiretrovirals for the treatment of human immunodeficiency virus-1 (HIV-1) infection. In 1995 it became the first protease inhibitor approved by the FDA, followed shortly by ritonavir in 1996, and remains in clinical use today due to a relatively benign adverse effect profile as compared to other antiretroviral therapies.[A214382] While its efficacy was initially limited by exceptionally poor oral bioavailability (approximately 4%),[L3450] its current indications require the co-administration of ritonavir - a potent enzyme inhibitor - that increases the bioavailability and subsequent serum concentrations of saquinavir, thus dramatically improving antiviral activity.[A214382,L3450,L14351]
Synonyms	Saquinavir mesylate Saquinavir
Brand Names	Fortovase Roche Invirase Fortovase Invirase - Cap 200mg
Indication	Saquinavir is indicated, in combination with ritonavir and other antiretroviral agents, for the treatment of HIV-1 infection in patients 16 years of age and older.[L3450]
