    Tacrolimus Time in Therapeutic Range Predicts Adverse Clinical Outcomes in the First Year of Kidney Transplant.

    S. Davis, J. Gralla, P. Klem, A. Wiseman, J. Cooper.

    University of Colorado, Aurora, CO

    Tacrolimus (TAC) has a narrow therapeutic range, with its upper bounds limited by serious toxicities while TAC minimization strategies have demonstrated immunologic risk. Monitoring the…
