 Aidsmap Saquinavir - overview
A small study has shown that ritonavir-boosted saquinavir alone may be an effective induction treatment in induction and maintenance therapy of patients with advanced HIV infection.
Saquinavir is cleared from the body more slowly by women than men, so the drug reaches higher levels in the blood and brings about better virological responses in women (Fletcher 2004).
For research into saquinavir plus the NNRTIs, see the relevant NNRTI entry in Drugs used by people with HIV.

 Sex-Based Differences in Saquinavir Pharmacology and Virologic Response in ACTG Study 359
The objective of the present study was to investigate relationships among concentrations of saquinavir, saquinavir inhibitory quotient (IQ), characteristics of patients, and virologic response.
ACTG 359 was designed such that the protease inhibitor saquinavir was the common drug in all 6 arms of the study.
Females had significantly higher concentrations of saquinavir than did males, and, consistent with the relationship between exposure to saquinavir and virologic response, a greater proportion of females than males had HIV RNA values ≤500 copies/mL at week 16.

 Atazanavir enhances saquinavir hard-gel concentrations in a ritonavir-boosted once-daily regimen
The high saquinavir drug levels achieved by boosting with ritonavir were further increased with the addition of atazanavir.
We have found no data in the literature on the effect of atazanavir on P-glycoprotein drug transport, and so this suggested explanation for the observed results is, at this stage, purely hypothetical.

 TAG: Ten texts on saquinavir
Saquinavir, like ddC, is the most potent drug of its class – in vitro.
We believe the initial labeling for Saquinavir should include a prominent box warning that use of Saquinavir may limit the clinical and virological utility of future protease inhibitors, and that physicians and patients must be educated about this possibility in Roche promotional materials.
Examples of such behavior are legion, from the fiasco that was ddC to the joke that is the current formulation of saquinavir to the curious decision by the Basel-based pharmaceutical giant to drastically curtail development of valganciclovir, the oral ganciclovir prodrug which offered the hope for finally being an effective prophylaxis for cytomegalovirus (CMV) disease.

 The Body: HIV Inhibitor: Boosted Saquinavir Shows Significant Safety Benefit Over Boosted Crixivan
Fifty-seven percent of patients who received at least one dose of the saquinavir therapy had undetectable HIV levels (less than 50 copies/mL) at 48 weeks, compared to 46 percent in the boosted indinavir arm of the study at 48 weeks.
Among patients who completed 48 weeks of therapy, HIV blood levels were suppressed to less than 50 copies/mL in 79 percent of patients on boosted saquinavir and in 77 percent of patients on boosted indinavir.
One hundred patients had at least one severe and/or life threatening adverse event: 65 (41 percent) in the boosted indinavir arm vs. 35 (24 percent) in the boosted saquinavir arm.
