Brief summary
Study to compare pharmacokinetics of tacrolimus prolonged-release (PR) capsules and Advagraf® PR capsules in stable kidney transplant patients.
Detailed description
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.
Interventions
Advagraf®1 mg and 5 mg prolonged-release hard capsules once daily (reference medicinal product).
Tacrolimus 1 mg and 5 mg prolonged release hard capsules (Sandoz) once daily (test medicinal product)

Eligibility
Inclusion criteria
* Male or female patients aged ≥18 years; * Patients with a Body Mass Index (BMI) included in the interval \[18.5-33.0\] kg/m²; * Patients who received a primary kidney transplant at least 12 months prior to study entry
Exclusion criteria
* Evidence or suspicion of ongoing or persistent, acute or chronic rejection; * Requirement for dialysis within the six months prior to study entry; * Glomerular filtration rate (GFR) \<30 mL/min * Pregnant or breastfeeding women, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test; * Intolerance to tacrolimus, excipients (including lactose, fructose or galactose), or similar products;
