Enteric-coated mycophenolate sodium

Abstract

Importance of the field: Mycophenolic acid (MPA) therapy is a fundamental component of most post-transplant immunosuppressive regimens. Side effects, however, are common and frequently necessitate dose reductions or discontinuations.Areas covered in this review: Enteric-coated mycophenolate sodium (EC-MPS) is designed to improve the gastrointestinal (GI) tolerability of MPA. This review assesses the pharmacology, efficacy and safety of EC-MPS.What the reader will gain: An understanding of the use of EC-MPS in solid organ transplantation and the key trials examining the GI impact of EC-MPS versus the immediate-release mycophenolate mofetil (MMF) formulation. The article also addresses the possible impact of proton pump inhibitor therapy, and the optimal MPA dose with different concomitant immunosuppressants.Take home message: Evidence from blinded trials using standard reporting measures or patient-reported outcomes has not confirmed a significant improvement in the GI symptom burden using EC-MPS. Several open-label studies, however, have consistently shown an improvement in GI tolerability with EC-MPS, which can permit restoration of the optimal MPA dose. EC-MPS has equal efficacy and possibly a different tolerability profile to MMF, thus offering a choice to physicians and their patients, particularly those experiencing MMF-related GI symptoms, diabetic patients or those in whom an MPA dose reduction is required.
