The effect of two varieties of grapefruit juice (white and ruby red) and its selected components (naringin, naringenin, and bergamottin) was investigated on the activity of the P-glycoprotein (P-gp) in male Sprague-Dawley rats. Talinolol, a nonmetabolized P-gp substrate, was used as a marker compound. The white grapefruit juice (GFJ) had a minor effect on talinolol pharmacokinetics, but the ruby red GFJ reduced the C max and the AUC (0-infinity) by 60% and 50% of the control, respectively. However, among the GFJ constituents tested, bergamottin (0.22 mg/kg) was the most potent component augmenting the C max and the AUC (0-infinity) of talinolol by 2.4- and 1.8-fold, respectively, if compared to the control group. The flavonoids naringenin (0.7 mg/kg) and naringin (2.4 and 9.4 mg/kg) had a similar effect increasing the talinolol C max and AUC (0-infinity) by 1.5- to 1.8-fold, respectively. In conclusion, the effect of GFJ on P-gp activity seems to depend on the variety, the concentration of compounds in the juice, and the composition of different ingredients.
