Cyclosporine is a commonly used immunosuppressive drug in patients receiving transplants. LCMSMS methods have higher specificity for the parent compound than Immunoassay. Therapeutic drug monitoring is useful to optimize dose and avoid toxicity. High cyclosporine levels can lead to nephrotoxicity; low levels can lead to organ rejection following transplant. Peak concentrations are reached at around 3.5 hours after oral dosage. Elimination half-life is 10-27 hours.
Optimum time to collect sample is 1 hour before next dose.
Do not use gel barrier tubes for sample collection.
