No Interaction Expected
Quality of Evidence:
Coadministration has not been studied but based on metabolism and clearance a clinically significant interaction is unlikely. Azithromycin is mainly eliminated via biliary excretion and animal data suggest this may occur via P-glycoprotein and MRP2. Ritonavir could potentially increase azithromycin exposure (inhibition of P-glycoprotein and MRP2), however, no a priori dosage adjustment is recommended for azithromycin.
