A Prospective Study to Investigate Mycophenolic Acid (MPA) Exposure Through Area Under the Curve (AUC) in Renal Transplants Recipients Treated With Mycophenolate Mofetil (MMF) and After Conversion to Mycophenolate Sodium (EC-MPS)

The conversion will be performed abruptly for all patients. Mycophenolate mofetil will be discontinued one day before the day of conversion (Day 1). Mycophenolate sodium will be introduced on day 1 with equivalent doses.

Mycophenolate mofetil dose will be maintained or adjusted to keep 30 to 60 mg\*h ml-1.
