Model Description

Name:

indirect_pd_pop

Title:

Indirect_PKPD_model

Author:

PoPy for PK/PD

Abstract:

A indirect (i.e. uses delay compartments) PD Model, based on the amount of drug in the body, delayed by two lag compartments
The amount in the central compartment is determined by K, which has been estimated for each individual.
The amount in the central compartment influences the rate of removal of a biomarker (KOUT).
Keywords:

pd; one compartment model; indirect; delay compartment
