Ciclosporin is an immunosuppressant that is used to prevent rejection after solid organ (heart, kidney, liver, pancreas or lung) transplantation. Ciclosporin has a narrow therapeutic range with frequent adverse effects making therapeutic drug monitoring essential for monitoring whole blood concentrations during therapy (particularly in individuals co-administered therapeutic drugs), adjusting dose to optimise immunosuppression while minimizing toxicity, and evaluating patient compliance.

Read MoreMost individuals display optimal response to ciclosporin with C0 trough levels of 100 to 400 ng/mL. Preferred therapeutic ranges may vary by transplant type, length of time post-transplant and unit protocols. Please contact the original transplant unit for organ-specific therapeutic ranges.
Therapeutic ranges are based on trough levels, i.e. blood drawn immediately before a scheduled dose. Blood drawn at other times will yield higher results. -
Reference Ranges:
Therapeutic ranges vary with type of transplant and length of time post transplant.
