cyclosporine and liver transplantation: Will the midazolam test make blood level monitoring obsolete?
Paul B. Watkins – 1 September 1995 – Immunosuppression therapy with cyclosporine is often hampered by significant interindividual variability in the metabolic clearance of the drug. It has been suggested that much of the variability in cyclosporine clearance is due to differences in the cytochrome P450 3A4 (CYP3A4) content in the liver and intestinal mucosa. A study was conducted in liver transplant recipients to characterize hepatic CYP3A4 variability during the first 10 days after surgery. The formation of 1′‐hydroxymidazolam (1′‐OH MDZ) was followed in the plasma after i.v.
