पोसाकोनाज़ोल और सिरोलिमस का इंटरैक्शन

Coadministration of Noxafil with the following drugs is contraindicated; Noxafil increases concentrations and toxicities of: Sirolimus ( 4.2 , 7.2 )

Use with Sirolimus Noxafil is contraindicated with sirolimus.

Concomitant administration of Noxafil with sirolimus increases the sirolimus blood concentrations by approximately 9-fold and can result in sirolimus toxicity [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] .

Prevention or Management Sirolimus Posaconazole is contraindicated with sirolimus [see Clinical Pharmacology (12.3) ] .

CYP3A Substrates Immunosuppressants that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Posaconazole is a strong CYP3A4 inhibitor.

Interaction with Strong Inhibitors and Inducers of CYP3A4 and/or P-gp Avoid concomitant use of sirolimus with strong inhibitors of CYP3A4 and/or P-gp (such as ketoconazole, voriconazole, itraconazole, erythromycin, telithromycin, or clarithromycin) or strong inducers of CYP3A4 and/or P-gp (such as rifampin or rifabutin) [ see Drug Interactions (7.2) ].

• Avoid concomitant use with strong CYP3A4/P-gp inducers or strong CYP3A4/P-gp inhibitors that decrease or increase sirolimus concentrations ( 7.4 , 12.3 ).

Strong Inducers and Strong Inhibitors of CYP3A4 and P-gp Avoid concomitant use of sirolimus with strong inducers (e.g., rifampin, rifabutin) and strong inhibitors (e.g., ketoconazole, voriconazole, itraconazole, erythromycin, telithromycin, clarithromycin) of CYP3A4 and P-gp.

Inducers of CYP3A4 and P-gp may decrease sirolimus concentrations whereas inhibitors of CYP3A4 and P-gp may increase sirolimus concentrations.

Use with Cyclosporine Cyclosporine, a substrate and inhibitor of CYP3A4 and P-gp, was demonstrated to increase sirolimus concentrations when co-administered with sirolimus.
