WebSome drugs, like certain statins used to lower cholesterol, are broken down by enzymes. As shown above, grapefruit juice can block the action of these enzymes, increasing the amount of drug in the body and may cause more side effects. Other drugs, like fexofenadine, are moved by transporters into the body’s cells.
