Vancomycin monitoring: one or two serum levels?

abstract：BACKGROUND:Tacrolimus pharmacokinetics in obese patients have been poorly studied. Herein, the authors explored the impact of obesity on tacrolimus exposure in kidney transplant recipients (KTRs) and estimated a more suitable initial dosage in this population. METHODS:A retrospective, observational, monocentric case-c...
