What is the difference between grapefruit and pink grapefruit?

The pink varieties of grapefruit share the same qualities as other grapefruit, but they have an added advantage. Among the pigments that color the flesh of the grapefruits are carotene pigments: beta-carotene, which gives the grapefruit some of its Vitamin A; and lycopene, which causes the reddish color.

What compound in grapefruit that interacts with drugs?

Grapefruit contains compounds known as furanocoumarins that block the CYP3A4 enzymes. When grapefruit juice is consumed, the enzyme's ability to break down the drug for elimination is decreased. Blood levels of the drug may rise, resulting in a risk for new or worsened side effects.

Why can’t you eat grapefruit with certain meds?

Many drugs are broken down (metabolized) with the help of a vital enzyme called CYP3A4 in the small intestine. Grapefruit juice can block the action of intestinal CYP3A4, so instead of being metabolized, more of the drug enters the blood and stays in the body longer. The result: too much drug in your body.

Is it OK to eat grapefruit with blood pressure medicine?

How does grapefruit juice inhibit drug metabolism?

Why does grapefruit juice inhibit CYP3A4?

CYP3A4 = cytochrome P450 enzyme 3A4. The chemicals in grapefruit involved in this interaction are the furanocoumarins. Furanocoumarins are metabolized by CYP3A4 to reactive intermediates that bond covalently to the active site of the enzyme, causing irreversible inactivation (mechanism-based inhibition).

Does grapefruit inhibit vitamin absorption?

Dear S.M.: There is no evidence that vitamin or mineral supplements are affected by grapefruit juice in the same way it affects certain medications.

Does grapefruit juice inhibit liver enzymes?

Abstract. In the recent time, several in vitro and in vivo studies have shown the inhibitory effect of grapefruit juice on metabolism of xenobiotics catalyzed by liver oxidative enzymes

oxidative enzymes
An oxidative enzyme is an enzyme that catalyses an oxidation reaction. Two most common types of oxidative enzymes are peroxidases, which use hydrogen peroxide, and oxidases, which use molecular oxygen. They increase the rate at which ATP is produced aerobically.
