- Abstract
Purpose: Various first-line recommended antiretroviral therapy (ART) regimens have different drug-drug interaction (DDI)/contraindication profiles. The aim of this study was to estimate the rate of potential DDIs/contraindications of real-world prescribed non-ART comedication with first-line recommended ART in people living with HIV (PLHIV) in Germany., Methods: A retrospective, cross-sectional cohort design was used to collect non-ART comedication prescription data from a representative sample of a German health insurance claims database. PLHIV who were prescribed ART during 2016 were included in the analysis. Patients were stratified by sex, age, comorbidities, and time on ART. Prescribed comedications were used to estimate potential DDIs/contraindications for each recommended first-line ART per patient based on criteria from www.hiv-druginteractions.org., Results: Records from 2680 PLHIV were analyzed. Prescriptions for non-ART comedications were common (mean of seven per patient in the overall population, 10.2 in PLHIV aged 50 years and older). Antiretroviral regimens with the lowest proportion of patients with at least 1 potential DDI/contraindication were unboosted integrase inhibitor, non-tenofovir disoproxil fumarate-based regimens that included raltegravir + emtricitabine/tenofovir alafenamide fumarate (13%), dolutegravir + lamivudine (14%), dolutegravir/abacavir/lamivudine (14%), dolutegravir/emtricitabine/tenofovir alafenamide fumarate (15%), and bictegravir/emtricitabine/tenofovir alafenamide fumarate (19%). Boosted regimens and efavirenz-based regimens presented the highest potential for DDIs/contraindications., Conclusions: Comedication with potential DDIs/contraindications with ART is frequently prescribed among PLHIV in Germany. Potential risks for DDIs/contraindications vary by ART, with the lowest potential seen in unboosted integrase strand transfer inhibitor-based regimens, including raltegravir + emtricitabine/tenofovir alafenamide fumarate, followed by three dolutegravir-based regimens., (© 2020 John Wiley & Sons, Ltd.)
