Grapefruit Drug Interactions
Grapefruit and grapefruit juice have the potential to interact with numerous drugs. Organic compounds, furanocoumarin derivatives, interfere with the hepatic and intestinal enzyme cytochrome P450 isoform CYP3A4 and are believed to be primarily responsible for the effects. Bioactive compounds in grapefruit juice may also interfere with P-glycoprotein and organic anion transporting polypeptides (OATPs) either increasing or decreasing bioavailability of a number of drugs. Pomelo (the Asian fruit which was crossed with an orange to produce grapefruit) also contains high amounts of furanocoumarin derivatives. Some grapefruit-pomelo hybrids have practically no furanocoumarin content, and one is a commercially viable seedless type.

“He’d been numb a long time, years. All his nights down Ninsei, his nights with Linda, numb in bed and numb at the cold sweating center of every drug deal. But now he’d found this warm thing, this chip of murder. Meat, some part of him said. It’s the meat talking, ignore it.”
—William Gibson (b. 1948)
“In our interactions with people, a benevolent hypocrisy is frequently required—acting as though we do not see through the motives of their actions.”
