Interaction Details
Cyclosporine is classified as belonging to the following category: P-Glycoprotein Substrates
In vitro evidence shows that some methoxylated flavones including tangeretin, nobiletin, and heptamethoxyflavone, inhibit P-glycoprotein. Theoretically, these methoxylated flavones might increase absorption and blood levels of drugs that are transported by P-glycoprotein.
Some of these drugs include some chemotherapeutic agents (daunorubicin, docetaxel, etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), protease inhibitors (amprenavir, indinavir, nelfinavir, saquinavir), H2 antagonists (cimetidine, ranitidine), some calcium channel blockers (diltiazem, verapamil), corticosteroids, erythromycin, cisapride (Propulsid), fexofenadine (Allegra), cyclosporine, loperamide (Imodium), quinidine, and others.

Interaction Details
Cyclosporine is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
In vitro evidence suggests that methoxylated flavones might inhibit cytochrome P450 3A4 (CYP3A4). This effect seems to be structure-dependent, and does not occur with all methoxylated flavones. So far this interaction has not been reported in humans. Theoretically, concurrent use of certain methoxylated flavones with drugs metabolized by CYP3A4 might result in increased drug levels and an increased risk for adverse effects.
Some drugs metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), Pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline (Slo-bid, Theo-Dur, others), zileuton (Zyflo), Zolmitriptan (Zomig), and others.

Cyclosporine Overview
-
Cyclosporine and cyclosporine (modified) are used with other medications to prevent transplant rejection (attack of the transplanted organ by the immune system of the person who received the organ) in people who have received kidney, liver, and heart transplants. Cyclosporine (modified) is also used alone or with methotrexate (Rheumatrex) to treat the symptoms of rheumatoid arthritis (arthritis caused by swelling of the lining of the joints) in patients whose symptoms were not relieved by methotrexate alone. Cyclosporine (modified) is also used to treat psoriasis (a skin disease in which red, scaly patches form on some areas of the body) in certain patients who have not been helped by other treatments. Cyclosporine and cyclosporine (modified) are in a class of medications called immunosuppressants. They work by decreasing the activity of the immune system.
