Question:
Wagner-Nelson method is used to determine the rate constants:
Wagner-Nelson method is used to determine the rate constants:
Show Hint
Wagner-Nelson = 1 Compartment Absorption; Loo-Riegelman = 2 Compartment Absorption.
Updated On: May 25, 2026
- Dissociation constants rate
- Absorption rate constants
- Elimination rate constants
- Distribution rate constant
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
The Wagner-Nelson method is a mathematical technique used in pharmacokinetics to analyze drug absorption from plasma concentration-time data.
Step 2: Meaning
It involves calculating the cumulative amount of drug absorbed into the systemic circulation over time relative to the total amount absorbed.
Step 3: Analysis
Unlike the Loo-Riegelman method, which is used for multi-compartment models, the Wagner-Nelson method is specifically designed for one-compartment models to estimate the absorption rate constant ($k_a$).
Step 4: Conclusion
Therefore, this method is primarily utilized for determining absorption rate constants. Final Answer: (B)
