“Based on these results, the verapamil dosage should be adjusted when given with naringin or a naringin-containing dietary supplement.”
“Compared with the control group (given verapamil alone), the Ka, Cmax and AUC of verapamil were significantly (p<0.05 or p<0.01) increased in the pretreatment of naringin , However there were no significant change in Tmax and t1/2 of verapamil.”
“Consequently, pretreatment of naringin significantly (p<0.05, p<0.01) increased the AB% of verapamil significantly in a dose dependent manner (p<0.05 or p<0.01), and elevated the RB% of verapamil by 1.26- to 1.69-fold.”
“In conclusion, pretreatment of naringin enhanced the oral bioavailability of verapamil.”
“ Naringin pretreatment significantly altered the pharmacokinetic parameters of verapamil.”
“the MR of verapamil were significantly (p<0.05) increased in the pretreatment of naringin , implying that pretreatment of naringin may effectively inhibit the CYP3A4-mediated metabolism of verapamil.”
