A Comparison of Adherence Rates to Ritonavir and Its Accompanying Protease Inhibitor

Details and patient eligibility
About
Pharmacologic boosting of protease inhibitors with ritonavir has become standard practice in antiretroviral therapy. Patients are instructed to take ritonavir at the same time as its accompanying protease inhibitor. However, ritonavir is unpopular with many patients because of its large size and because of the recommended need for refrigeration. This study will test the hypothesis that adherence to ritonavir is inferior to adherence to its accompanying protease inhibitor in patients receiving such therapy.
Full description
The study staff will employ MEMS caps to prospectively measure adherence to ritonavir and its accompanying protease inhibitor over 24 weeks of follow-up. Paired sample t-tests will be employed to compare adherence to the two agents, and secondary analyses will be conducted to evaluate the chronologic concordance of ritonavir and accompanying protease inhibitor dosing.
