…in perfusion > decrease in tubular function Increased uptake of Indium 111 labeled platelets or Tc-99m in colloid Therapy Responds to decreased cyclosporine Responds to increased steroids or antilymphocyte globulin A form of a cyclosporine-associated nephropathy is characterized by serial deterioration in renal function and morphologic changes in the kidneys.
In the event of severe and unremitting rejection, when rescue therapy with pulse steroids and monoclonal antibodies fail to reverse the rejection episode, it may be preferable to switch to alternative immunosuppressive therapy rather than increase the Neoral dose to excessive blood concentrations.
Predisposing factors, such as hypertension, hypomagnesemia, hypocholesterolemia, high-dose corticosteroids, high cyclosporine blood concentrations, and graft-versus-host disease, have been noted in many but not all of the reported cases.

Use of Cytochrome P450 3A4 Inhibitors Ritonavir and other strong cytochrome P450 3A4 (CYP3A4) inhibitors can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .
Use caution with the coadministration of azelastine hydrochloride and fluticasone propionate nasal spray and other potent CYP3A4 inhibitors, such as ketoconazole [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .
• Other potent CYP3A4 inhibitors, such as ketoconazole: use caution with coadministration.
Cytochrome P450 3A4 Ritonavir (a strong CYP3A4 inhibitor) significantly increased plasma fluticasone propionate exposure following administration of fluticasone propionate aqueous nasal spray, resulting in significantly reduced serum cortisol concentrations [see Clinical Pharmacology ( 12.3 )] .
Caution should be exercised when azelastine hydrochloride and fluticasone propionate nasal spray is coadministered with ketoconazole and other known strong CYP3A4 inhibitors.
