We aimed to explore the major active components in grapefruit juice (GFJ), orange juice (OJ), and apple juice (AJ) that are responsible for OATP2B1-mediated drug interactions, by means of in vitro studies using Xenopus oocytes expressing OATP2B1 with a typical OATP2B1 substrate, estrone-3-sulfate. All three juices inhibited OATP2B1-mediated estrone-3-sulfate uptake with half-maximum inhibition (IC(50) ) values of 0.222% (GFJ), 0.807% (OJ), and 2.27% (AJ). Eight major flavonoids (naringin… 
Inhibitory Effects of Cranberry Juice and Its Components on Intestinal OATP1A2 and OATP2B1: Identification of Avicularin as a Novel Inhibitor.
TLDR
Cranberry juice may cause drug interactions with OATP substrates, and fexofenadine exposure was significantly reduced by cranberry juice, a pharmacokinetic experiment revealed.
Potential Risk of Food-Drug Interactions: Citrus Polymethoxyflavones and Flavanones as Inhibitors of the Organic Anion Transporting Polypeptides (OATP) 1B1, 1B3, and 2B1
TLDR
All flavonoids investigated might contribute to the intestinal OATP2B1-based interactions with drugs observed with citrus juices or fruits, but there might be a risk when they are consumed as medicines or as dietary supplements.
Substrate- and Dose-Dependent Drug Interactions with Grapefruit Juice Caused by Multiple Binding Sites on OATP2B1
TLDR
Findings indicate that only fexofenadine is expected to interact with GFJ on OATP2B1 at therapeutic concentrations, in accordance with the clinical observations.
Organic anion-transporting polypeptide (OATP) 2B1 contributes to the cellular uptake of theaflavin.
Enzyme‐ and transporter‐mediated beverage–drug interactions: An update on fruit juices and green tea
TLDR
The multiple mechanisms through which beverages can alter drug disposition are highlighted and an update on the new findings of beverage–drug interactions is provided, with a focus on fruit juices and green tea.
Honey flavonoids inhibit hOATP2B1 and hOATP1A2 transporters and hOATP-mediated rosuvastatin cell uptake in vitro
TLDR
The found data indicate that several of the tested natural compounds could potentially affect drug cellular uptake by hOATP2B1 and/or hO ATP1A2 at relative low concentrations, a finding which suggests their potential for food–drug interactions.
Effects of one-time apple juice ingestion on the pharmacokinetics of fexofenadine enantiomers
TLDR
It is suggested that OATP2B1 plays an important role in the stereoselective pharmacokinetics of fexofenadine and that one-time apple juice ingestion probably inhibits intestinal O ATP2 B1-mediated transport of both enantiomers.
Grapefruit and medications may be a deadly mix- An overview
TLDR
The mechanism for this interaction is the inhibition of cytochrome P-450 3A4 in the small intestine, resulting in a significant reduction of drug pre-systemic metabolism.

TLDR
There is no evidence, so far, that OATP inhibition affects the absorption of psychotropic medications, and there is no room for complacency because the field is still nascent and because the necessary studies have not been conducted.

Role of furanocoumarin derivatives on grapefruit juice-mediated inhibition of human CYP3A activity.
TLDR
All six furanocoumarins showed stronger CYP3A inhibitory potencies after preincubation in the presence of NADPH, suggesting that both competitive and mechanism-based inhibition occur in a grapefruit juices-drug interaction.
A furanocoumarin-free grapefruit juice establishes furanocoumarins as the mediators of the grapefruit juice-felodipine interaction.
TLDR
Furanocoumarins are the active ingredients in GFJ responsible for enhancing the systemic exposure of felodipine and probably other CYP3A4 substrates that undergo extensive intestinal first-pass metabolism.
Naringin is a Major and Selective Clinical Inhibitor of Organic Anion‐Transporting Polypeptide 1A2 (OATP1A2) in Grapefruit Juice
TLDR
Naringin most probably directly inhibited enteric OATP1A2 to decrease oral fexofenadine bioavailability and may be the first report of a single dietary constituent clinically modulating drug transport.
Mechanisms of enhanced oral availability of CYP3A4 substrates by grapefruit constituents. Decreased enterocyte CYP3A4 concentration and mechanism-based inactivation by furanocoumarins.
TLDR
The effect of grapefruit juice on oral availability of CYP3A4 substrates can be largely accounted for by the presence of 6',7'-dihydroxybergamottin although other furanocoumarins probably also contribute.
Species Difference in the Effect of Grapefruit Juice on Intestinal Absorption of Talinolol between Human and Rat
TLDR
The present study indicated that the species difference in the effect of GFJ on intestinal absorption of talinolol between humans and rats may be due to differences in the affinity of naringin for OATP/Oatp and MDR1/Mdr1 transporters between the two species.
Further characterization of a furanocoumarin-free grapefruit juice on drug disposition: studies with cyclosporine.
TLDR
Furanocoumarins mediate, at least partially, the cyclosporine-GFJ interaction in vivo, and a plausible mechanism involves the combined inhibition of enteric CYP3A4 and P-glycoprotein.
Inactivation of cytochrome P450 3A4 by bergamottin, a component of grapefruit juice.
TLDR
Results indicate that BG, the primary furanocoumarin extracted from grapefruit juice, is a mechanism-based inactivator of P450 3A4.
Apple juice greatly reduces systemic exposure to atenolol.
TLDR
Apple juice markedly reduced systemic exposure to atenolol and the genetic variation of SLCO2B1 c.1457C>T had a minimal effect on the pharmacokinetics of atenorol when the drug was administered with water or apple juice.
Differential effect of grapefruit juice on intestinal absorption of statins due to inhibition of organic anion transporting polypeptide and/or P-glycoprotein.
TLDR
Oatp and/or P-gp contribute to the intestinal absorption of statins, and the differential effect of GFJ on pravastatin and pitavastatin absorption is at least partly accounted for by the different inhibitory effects of naringin on these transporters.
Polyphenols are intensively metabolized in the human gastrointestinal tract after apple juice consumption.
TLDR
The gastrointestinal passage seems to play an important role in the colonic availability of apple polyphenols, and the mean degree of polymerization of the procyanidins varied depending on the time point of excretion.
