← Human Body & HealthA patient receives a drug with high protein binding and a small volume of distribution. If a second drug displaces the first from plasma proteins, which consequence follows?
A)Reduced drug clearance rate
B)Decreased free drug concentration
C)Increased free drug concentration✓
D)Prolonged drug half-life significantly
💡 Explanation
When a drug with a small volume of distribution is displaced from plasma proteins, the free drug concentration increases because the drug is now less bound and more available in the plasma; therefore, the concentration increases, rather than decreasing or affecting clearance rates significantly, given the drug's distribution.
