This paper reports a case of increase in the blood level of tacrolimus following intake of pomelo in a renal transplant recipient. To clarify the mechanism of this increase in the blood level of tacrolimus, the authors investigated the effect of pomelo juice extract on the activities of CYP3A4 and P-glycoprotein, in comparison with that of extract of grapefruit juice (GFJ). The results of their study indicate that pomelo constituents inhibit the activity of CYP3A4 and may lead to an increase in the blood level of orally administered tacrolimus. Therefore, drugs whose kinetics can be altered by grapefruit may also interact with grapefruit-related citrus fruits, such as pomelo. was launched in 1996 and has emerged as a comprehensive aggregator of websites and science references in the applied life science pomology.
