:Name: direct_pd

:Title: Direct PD Model

:Author: PoPy for PK/PD

:Abstract: 

| A simple direct PD Model, based on the amount of drug in the body.
| The amount in the central compartment is determined by K, which has been previously estimated for each individual.
| The amount in the central compartment influences the rate of removal of a biomarker (KOUT).

:Keywords: pd; one compartment model; direct
