Answer to Question 1

C
Feedback:
Sirolimus may have synergistic effects with cyclosporine because it has a different mechanism of action, and prescribers may order both drugs in combination. However, because the two drugs are metabolized by the same liver CYP3A4 enzymes, cyclosporine can increase blood levels of sirolimus, potentially to toxic levels. Consequently, it is essential that the drugs not be given at the same time; patients should take sirolimus 4 hours after a dose of cyclosporine.

Answer to Question 2
