title: Renal transplant patients with gastrointestinal intolerability to mycophenolate mofetil: conversion to enteric-coated mycophenolate sodium.
abstract: The introduction of mycophenolate mofetil (MMF) was an important advance in immunosuppressive therapy, although its use is limited by adverse gastrointestinal events. Enteric-coated mycophenolate sodium (EC-MPS; myfortic) has been developed to avoid these side effects. Recent clinical trials have demonstrated that EC-MPS is a safe drug in both de novo and maintenance renal transplant patients. In this prospective study, therapeutically equivalent doses of EC-MPS were administered to 39 stable kidney transplant patients receiving MMF. After 3 months of treatment with EC-MPS the incidence of adverse gastrointestinal events was lower (15.8% of the patients). There were higher levels of mycophenolic acid after conversion to EC-MPS, probably due to better absorption. These factors allowed decreased doses and levels of calcineurin inhibitors without increasing the risk of graft rejection. At 3 months postconversion, serum creatinine improved from the mean baseline value of 1.83 +/- 0.12 mg/dL to 1.70 +/- 0.10 mg/dL. In conclusion, EC-MPS was well tolerated in maintenance renal transplant patients with adverse gastrointestinal events secondary to MMF.
