Protonpumpe- hæmmere og H2- receptor- anatagonister: protonpumpe- hæmmere og H2- receptor - antagonister (f. eks. omeprazol eller ranitidin) kan nedsætte koncentrationen af protease- hæmmere, som administreres samtidig.
Proton pump inhibitors and H2-receptor antagonists: proton pump inhibitors and H2-receptor antagonists (e.g. omeprazole or ranitidine) may reduce concentrations for co-administered protease inhibitors.
