If a drug with high protein binding and a small molecular volume is administered intravenously, which consequence follows regarding its initial distribution?

A)Rapid distribution to all tissues
B)Immediate renal clearance increase
C)Confined distribution to plasma volume
D)Enhanced penetration into brain tissue

💡 Explanation

Because the drug binds extensively to plasma proteins and has a small molecular volume, its distribution will be limited to the plasma. Therefore, it remains largely in the bloodstream rather than distributing widely into tissues, rather than being cleared quickly by the kidneys or penetrating into the brain.
