Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Tacrolimus is a medication given to transplant patients to help prevent rejection. The purpose of this study is to see if tacrolimus can be taken once a day instead of twice a day in kidney transplant patients. Transplant patients are required to take several medications to prevent rejection and to treat complications after their transplantation. Because of the complicated dosing schedule, it can be difficult for patients to follow their medication schedule. Taking fewer medications less frequently may help transplant patients to better manage their drug therapy. Tacrolimus is better absorbed in the body if it is taken in the morning than if it is taken in the evening. This suggests that tacrolimus can be taken once every morning instead of twice daily in order to produce appropriate drug exposure to prevent organ rejection without increased side effects.
