If a drug exhibits decreased hepatic clearance because of competitive inhibition with another co-administered medication, which consequence follows?

A)Reduced steady-state drug concentration
B)Increased drug plasma half-life
C)Enhanced drug first-pass metabolism
D)Decreased drug volume distribution

💡 Explanation

When hepatic clearance decreases due to competitive inhibition, the drug's elimination rate slows down, because the liver's capacity to metabolize the drug diminishes, therefore the drug remains in the body longer, leading to an increased plasma half-life, rather than a decreased half-life or altered volume of distribution.
