Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this pharmacokinetic study is to examine a possible drug-drug interaction of Pantoprazole on the bioavailability mycophenolic acid.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is a randomized open-label 4-sequence 4-period pharmacokinetic cross-over study. The objective of the pharmacokinetic study is to examine a drug-drug interaction of pantoprazole on the bioavailability mycophenolic acid administered as either mycophenolate mofetil (Cellcept(R) or mycophenolate Sodium; EC-MPS (Myfortic (R) in stable renal allograft recipients under maintenance immunosuppressive therapy (cyclosporine +/- low dose glucocorticoids).
