Question:
Formula of Renal clearance
Formula of Renal clearance
Show Hint
Clearance = How fast it's "Gone" divided by how much is "There."
Updated On: May 25, 2026
- Absorption rate/Plasma concentrations
- Absorption rate + Plasma concentrations
- Elimination rate/plasma concentrations
- Absorption rate - Plasma concentrations
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Renal clearance ($Cl_{R}$) is a pharmacokinetic parameter that quantifies the ability of the kidneys to remove a drug from the plasma.
Step 2: Meaning
It is defined as the volume of plasma cleared of the drug per unit time via the kidneys.
Step 3: Analysis
Mathematically, clearance is the ratio of the rate of drug elimination (excretion rate) to the drug concentration in the plasma.
Step 4: Conclusion
The formula is $Clearance = \frac{\text{Elimination Rate}}{\text{Plasma Concentration}}$. Final Answer: (C)
