Darunavir is a nonpeptidic protease inhibitor marketed
as part of a ritonavir-boosted regimen for ARVexperienced
patients with viral mutations. Patients with
limited treatment options due to resistance and/or intolerance
to other agents are currently the ideal candidates
for a darunavir-based regimen, particularly when
combined with enfuvirtide. A genotype can serve to
guide therapy in this scenario. The daily pill burden is
slightly higher than that of a lopinavirMtonavir-based regimen
for treatment-experienced patients (8 vs 6 pills) and
identical to a tipranavirMtonavir-based regimen. The tolerability
appears comparable to other protease inhibitors
in the 48-week analysis. Future studies will define
darunavir's role and durability in treatment-naive patients
