None A 70-year-old patient was brought to the emergency room with a blood pressure of 76/60 mm Hg and low cardiac output. He was diagnosed with acute heart failure. Which of the following would be the most appropriate to improve his cardiac function?
Understand the Problem
The question is asking about pharmacology and drug administration, specifically focusing on enzyme systems that affect drug responses, routes of drug administration, and dosage forms designed to resist stomach liberation.
Answer
C. Cytochrome P450 enzymes
The final answer is C. Cytochrome P450 enzymes.
Answer for screen readers
The final answer is C. Cytochrome P450 enzymes.
More Information
Cytochrome P450 enzymes are crucial for metabolizing drugs and are a key factor in variations in drug response due to genetic differences.
Tips
It's important to remember that P450 enzymes metabolize a wide range of substances, affecting drug efficacy and safety.
