Model Description
*****************


:Name: dp_exponential

:Title: exponential_disease_progression_model

:Author: Andrew Cristinacce @ PoPy for PK/PD

:Abstract: 

| Specifies both the pop_gen and pop_fit subscripts.
| A exponential disease progression model, based on the concentration of drug in the central compartment.
| The amount in the central compartment is determined by CL/V, which has been previously estimated for each individual.
| The disease compartment increases exponentially over time, but is initially reduced by the drug concentration.

:Keywords: PD; Pharmacodynamics; one compartment model; exponential disease progression
