Research on grapefruit juice has shown that some components of this fruit, such as bergamotine and naringin, are potent inhibitors of cytochrome P450 3A4, an enzyme located in the intestine and liver that detoxifies the body of approximately 50% of the currently existing drugs.

On the other hand, the interaction of drugs with grapefruit juice causes a slower elimination of the drugs and an excessive stay in the body. For this reason, overdose phenomena are frequent after concomitant ingestion of grapefruit and medications.

In addition, it has been shown that drug interaction can also occur with the intake of modest amounts of grapefruit juice or fresh fruit (250 grams).

This enzymatic inactivation can last for a long period (around 3 days), so it would be advisable to avoid the intake of grapefruit-based products, including grapefruit juice, at least 72 hours before taking a medicine, and in the case if they are chronically medicated, they should opt for other drinks to lose weight and discard this juice.
