← Human Body & HealthA patient with liver cirrhosis experiences increased drug sensitivity. Which mechanism explains why drugs persist longer in their system?
A)Increased glomerular filtration rate
B)Enhanced hepatic blood flow
C)Reduced cytochrome P450 activity✓
D)Increased plasma protein binding
💡 Explanation
Reduced cytochrome P450 activity impairs the liver's ability to metabolize drugs, because these enzymes are crucial for detoxification. Therefore, drugs remain active longer in the system, rather than being quickly broken down and eliminated by the kidneys.
