Single-dose cyclosporine pharmacokinetics in various biological fluids of patients receiving allogeneic marrow transplantation.

abstract：INTRODUCTION:Proton pump inhibitors (PPIs) are often prescribed posttransplantation to prevent gastrointestinal complications. A series of recent studies have reported a relationship between PPI comedication and decreased mycophenolic acid (MPA) exposure. The objective of this subanalysis of the CLEAR data set was to d...
