Part Used : น้ำจากผลActivity : EFFECTS ON PHARMACOKINETICSolvent/Active Compound : 6',7'-DihydroxybergamottinType of experiment : humanType of animal : -Type of study : Open trialN(Total) : -N(Treatment) : -Sex : -Age : -Route : Oral administrationDose/Conc.(herb) : -Duration : -Type of interaction : PharmacokineticsInteraction with drug : Ciclosporin*/Cyclosporin/Cyclosporin A/Cyclosporine/CsA/CyADose/Conc.(drug) : -Result : NegativeRemark : Subjects were healthy subjects. Result: Seville orange juice had no influence on cyclosporine disposition.Note : Conclusions: 6'7'-Dihydroxybergamottin is not responsible for the effects of grapefruit juice on cyclosporine. Because the interaction did not occur with Seville orange juice despite reduced enterocyte concentrations of CYP3A4, inhibition of P-glycoprotein activity by other compounds in grapefruit juice may be responsible. Reduced enterocyte CYP3A4 by 6',7'-dihydroxybergamottin could be important for other drugs whose bioavailability is less dependent on P-glycoprotein. Data incomplete.
