Problem:
Medications/Supplements: Warfarin is metabolized by the cytochrome P450 system, and medications that inhibit this enzyme system (e.g., fluoroquinolones, erythromycin, metronidazoles, and amiodarone) can cause a supratherapeutic INR. In contrast, medications or supplements that induce this system (e.g., carbamazepine, phenobarbital, phenytoin, and St. John's Wort) can lead to a subtherapeutic INR. explain this statement to me in laments term that i can understand.
