Chrono and clinical pharmacokinetic study of tacrolimus in continuous intravenous administration

Abstract

This study proposes that intravenous administration is a safe and appropriate method to achieve the required blood concentration in patients with various tacrolimus metabolism in the early post-transplant period. As the oral tacrolimus absorption was found to be variable between preoperative and postoperative states in identical patients, the conversion dosage cannot be calculated from preoperative oral or postoperative intravenous pharmacokinetics. Frequent blood concentration monitoring is needed to ensure safe treatment.
