Abstract

The popular herbal medicine, St. John's wort, is a potent inducer of several cytochrome P450 enzymes, including CYP3A4, which plays a role in the metabolism of fentanyl. St. John's wort may also influence the expression of P-glycoprotein, which can alter the movement of drugs across the blood-brain barrier.
