Description¶
| Name: | circ_sin |
|---|---|
| Title: | Sine circadian model |
| Author: | Wright Dose Ltd |
| Abstract: |
A PD Model based on the amount of drug in the body.
The PD model uses a sine function which simulates a circadian rhythm for the generation of a biomarker.
The amount in the central compartment is determined by CL and V, PK patameters , which have been previosly estimated for each individual.
The amount in the central compartment influences the rate of production of a biomarker.
