There are multiple interactions reported between these two agents.

Interaction Details

Cyclosporine is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates

There's very preliminary evidence that berberine, a constituent of goldthread, might inhibit cytochrome P450 3A4 (CYP3A4) enzyme. So far, this interaction has not been reported in humans. However, watch for an increase in the levels of drugs metabolized by CYP3A4 in patients taking goldthread. Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), clarithromycin (Biaxin), indinavir (Crixivan), sildenafil (Viagra), triazolam (Halcion), and numerous others. Use goldthread cautiously or avoid in patients taking these drugs.

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.
