Study to compare pharmacokinetics of tacrolimus prolonged-release (PR) capsules and Advagraf® PR capsules in stable kidney transplant patients.
Initially, patients will enter a short screening period, and those who continue to meet the inclusion and exclusion criteria will be randomized to receive either test or reference medicinal product in Period 1. In period 2 they will switch to the other formulation. During the whole treatment period four full-pharmacokinetics profiles will be established.
