Which tacrolimus is better for black kidney transplant patients?

This study looks at two versions of a drug called tacrolimus, which helps prevent the body from rejecting a new kidney. It focuses on African American kidney transplant recipients to see if taking the drug once a day (extended release) is better for blood vessel health than taking it twice a day (immediate release). The study measures how stiff the blood vessels are and how well they adapt to each heartbeat. About 60 people will take part, and they will be followed for up to 24 months after their transplant.
