NRNP 6566 Mid-term Study Guide Week 1 to 5 Week 1 1. Describe the cytochrome P450 system. Describe how inducers and inhibitors affect the cytochrome system and how that affects the half-life of medications. Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and br...

NRNP 6566 Knowledge Check Week 3 Amiodarone has possible complex interactions with multiple medications. It has an effect on warfarin metabolism. Amiodarone is a potent inhibitor of cytochrome P450 enzymes and inhibition of these enzymes will cause an increased plasma concentration and decreased clearance; thereby increasing the prothrombin time and INR placing the patient at increased risk for bleeding complications. Hence, when given together, warfarin dose should be decreased and frequent...
