Saquinavir is an HIV protease inhibitor (PI) which, formulated as a hard-ge
l capsule (HCG), was the first drug of its class to become available for th
e treatment of patients with HIV infection. The limited bioavailability of
this drug was responsible for a reduced number of prescriptions when new PI
were available. Since 1997, combination therapy with ritonavir has improve
d the pharmacokinetics parameters resulting in a better clinical benefit. S
aquinavir (HGC) monotherapy is not yet recommended. Soft gel capsule (SGC)
has improved biodisponibility. Efficacy of SQV has been shown in clinical s
tudies in first and second line of treatment with Pl. Resistance profile is
favorable considering the low level of cross resistance with other Pl. Bet
ter knowledge of saquinavir could help giving back a place to this drug in
the anti HIV arsenal. (C) 2001, Masson, Paris.
