These chemicals inhibit key drug metabolizing enzymes, such as cytochrome P450 3A4 (CYP3A4). CYP3A4 is a metabolizing enzyme for almost 50% of drugs, and is found in the liver and small intestinal epithelial cells. If the active drug is metabolized by the inhibited enzyme, then the fruit will stop the drug being metabolized, leaving elevated concentrations of the medication in the body, which can cause adverse effects. Conversely, if the medication is a prodrug, it needs to be metabolised to be converted to the active drug. Compromising its metabolism lowers concentrations of the active drug, reducing its therapeutic effect, and risking therapeutic failure. Low drug concentrations can also be caused when the fruit suppresses drug absorption from the intestine. The effect of grapefruit juice with regard to drug absorption was originally discovered in 1989. Xanax (alprazolam) is a benzodiazepine (ben-zoe-dye-AZE-eh-peen). Alprazolam affects chemicals in the brain that may be unbalanced in people with anxiety. Xanax is used to treat anxiety disorders, panic disorders, and anxiety caused by depression.

Although many people are aware that grapefruit with many prescription medications when they are ingested together, very few understand the actual chemistry behind it or the effects they may experience. When it comes to grapefruit juice and medication, there are a few basic principles that help to explain the interactions between the two. In short, grapefruit blocks certain enzymes that would otherwise break down parts of medications and prevent them from being absorbed into the bloodstream; the amount of the medication actually absorbed is much less than what is ingested. When pharmaceutical companies develop dosages for their products, they will generally take these enzymes into consideration. However, when grapefruit juice destroys the enzymes, more of the medication than usual is able to enter the bloodstream; this may result in an increase in side effects and possible overdose. When patients consume Xanax and grapefruit together, they will often notice an increase in their drowsiness and dizziness. This is because more of the drug than was anticipated has entered the bloodstream. Grapefruit is a delicious citrus fruit with many health benefits.

Medications are processed in your liver and small intestine by a specialized group of proteins called cytochrome P450 (CYPs). CYPs break down medications, reducing the blood levels of many of them. Grapefruit and a few of its close relatives, such as Seville oranges, tangelos, pomelos and Minneolas, contain a class of chemicals called furanocoumarins.
