Abstract：
:The effect of grapefruit juice on the urinary excretion of 7-hydroxycoumarin after oral administration of 10 mg coumarin, as an index of cytochrome P450 dependent coumarin metabolism, has been investigated in an open, randomised cross over study in 13 healthy volunteers (7 female, 6 male). The percentage of 7-hydroxycoumarin found in urine was significantly decreased up to 8 h after simultaneous intake of 300 ml grapefruit juice. If the same volume of juice was swallowed 30 min prior to the administration of coumarin, 7-hydroxycoumarin excretion was delayed by up to 6 h. MRTexcr. of coumarin was 70% extended by coadministration of grapefruit juice. It appears that grapefruit flavonoids inhibit cytochrome P450 2A dependent metabolic pathways. The mechanism of cytochrome P450 inhibition by these flavonoids is still poorly understood.

临床试验,杂志文章,随机对照试验abstract：BACKGROUND:Tamoxifen is one of the cornerstones of endocrine therapy for breast cancer. Recently, the decreased activity CYP3A4*22 allele and the loss of function CYP3A5*3 allele have been described as potential factors that could help to explain the inter-patient variability in tamoxifen metabolism. The aim of this st...
