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

April 25, 2018 updated by: Jonathan Shuter, Montefiore Medical Center

A Comparison of Adherence Rates to Ritonavir (Soft-gel Capsules) and Its Accompanying Protease Inhibitor (PI) in Patients Receiving Ritonavir Boosted PI Regimens

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.

Study Overview

Status

Completed

Conditions

Detailed 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.
