التداخل بين سيكلوفوسفاميد وريتونافير

Immunosuppressants: cyclosporine, tacrolimus, sirolimus (rapamycin) ↑ immunosuppressants Therapeutic concentration monitoring is recommended for immunosuppressant agents when co-administered with ritonavir.

Effect of Other Drugs on Cyclophosphamide Exposure Protease Inhibitors Concomitant use of protease inhibitors may increase the concentration of cytotoxic metabolites and may enhance the toxicities of cyclophosphamide, including higher incidence of infections, neutropenia, and mucositis.

Monitor for increased toxicities in patients receiving protease inhibitors.

…toxicities: ● Azathioprine: Increased risk of hepatotoxicity (liver necrosis) ● Busulfan: Increased incidence of hepatic veno-occlusive disease and mucositis has been reported. ● Protease inhibitors: Increased incidence of mucositis Increased risk of hemorrhagic cystitis ● Radiation treatment: Increased risk of hemorrhagic cystitis may result from a combined…
