Fraction unbound (experiment) vs. Fraction unbound (plasma) #1702

Closed Ember26 closed 8 months ago

Ember26 commented 9 months ago

Hello! I am referring to the reply to a discussion on the difference between the fraction unbound plasma vs experiment: The Fraction unbound (experiment) is used for calculation of the specific renal clearance rate constant from renal clearance input value. So to correctly apply the measured or predicted renal clearance value to the model, the two Fraction unbound parameters should be equal. You should also consider this during parameter identification, if you are optimizing the fraction unbound.

My question is: if the two fraction unbound values must be equal and I want to do parameter identification, I must select both of them as Identification Parameters. However, the optimized values may not be identical. Is there a way to force the two values to be identical?
Looking forward to your reply. Thanks
