Mechanism and Risks of the 10 Most Frequent DDIs Among the POPVIH65 Cohort (n = 9076) in 2016

DNCIs, No. (%) Mechanism of Interaction Potential Risksa
PI or boost/inhaled glucocorticoidsb 739 (29) Inhibition of CYP3A4 yielding to a rise of plasma concentration of inhaled glucocorticoids Cushing syndrome, adrenal suppression, and other glucocorticoids toxicities
Atazanavir or rilpivirine/proton pump inhibitorsc 676 (27) Decrease of intestinal absorption of ARV yielding to a subtherapeutic concentration Ineffective ARV therapy
PI or boost/lercanidipine 285 (11) Inhibition of CYP3A4 yielding to a rise of plasma concentration of comedications Not documented (theoretically: hypotension and cardiac rhythm disorders)
PI or boost/alfuzosin 233 (9) Severe hypotension
PI or boost/domperidone 136 (5) Cardiac arythmia like QT interval prolongation
PI or boost/amiodarone 82 (3) Cardiac arythmia like QT interval prolongation
PI or boost/simvastatin 79 (3) Rhabdomyolysis
PI or boost/apixaban or rivaroxaban 67 (3) Bleeding
PI or boost/piroxicam 51 (2) Serious respiratory depression and hematologic abnormalities
Darunavir/injectable lidocaine 38 (2) Cardiac arythmia like QT interval prolongation
Other combinations 126 (6)

Abbreviations: ARV, antiretroviral; boost, ritonavir or cobicistat; DDIs, drug-drug interactions; PI, protease inhibitor (boosted or not); QT, .

aPotential risks are defined from the Liverpool HIV drug interactions website.

bInhaled glucocorticoids include aerosols of fluticasone or budesonide and nasal sprays of mometasone or triamcinolone.

cProton pump inhibitors include rabeprazole, omeprazole, lansoprazole, pantoprazole, and esomeprazole.
