Input: Question: Does conversion from twice-daily to once-daily tacrolimus reduce intrapatient variability in tacrolimus exposure?
Answer: Although conversion from Tac-TD to Tac-OD significantly reduces tacrolimus exposure as measured by C0 and seems safe, it does not reduce IPV in tacrolimus exposure.
Output:
no
