Does orange juice inhibit CYP3A4?

Does orange juice inhibit CYP3A4?

An increased incidence of side effects and toxicity may occur. Seville orange juice, a constituent of marmalade, also has been shown to inhibit CYP3A4. Regular orange juice, however, has no effect on the enzyme. In addition, limited data suggest that lime, star fruit, and pomegranate juice may reduce CYP3A4 activity.

What foods are CYP3A4 inhibitors?

The inhibition of CYP3A4 by grapefruit juice is probably the most well-known example of food-drug inhibition [76, 163]. It was suggested that the flavanone naringin, the predominant flavanone in grapefruit, might be responsible for the observed interaction effect [164].

Is grape juice a CYP3A4 inhibitor?

Scientific studies indicate that grapefruit and grapefruit juice inhibit CYP3A4, which metabolizes more than 65% of all drugs, as well as P-glycoprotein (P-gp) and a number of other metabolic enzymes and transporters.

What citrus fruits interact with medications?

Because the furanocoumarins in grapefruit juice are the primary culprits in drug interaction, it is important to note that furanocoumarins are also found in other citrus fruits such as pomelos, Seville oranges, and limes.

Does orange juice interact with medications?
