Select and explain. 
A. It is a prodrug, B. Gastrointestinal toxicity is common, C. It is used in transplant recipients where other drugs are not effective, D. It is highly nephrotoxic
D: It is highly nephrotoxic
Answer: D: It is highly nephrotoxic 
Explanation: Mycophenolate mofetil is a prodrug, its active metabolite is mycophenolic acid.
It is used as an immunosuppressant drug in solid organ transplant patients for refractory rejection and as an alterna­tive to cyclosporine /tacrolimus in patients who do not tolerate these drugs.

- Major toxicity is gastrointestinal (nausea, vomiting, diarrhea, abdominal pain). It can also cause hypertension and reversible neutropenia.
- Unlike cyclosporine and tacrolimus, it does not cause nephrotoxicity.
