********** MODEL NAME
PK model

********** MODEL NOTES

Simple linear one compartment PK model with 1st order absorption.

********** MODEL STATES
d/dt(Ad) = -ka*Ad + INPUT1
d/dt(Ac) =  ka*Ad - CL/Vc*Ac

********** MODEL PARAMETERS
ka = 1    # (1/hour) Absorption rate
CL = 3    # (L/hour) Apparent clearance
Vc = 60   # (L) Apparent volume of distribution
Tlag1 = 0 # (hour) Lagtime for INPUT1
Tk0 = 0   # (hour) Zero order absorption rate for INPUT1

********** MODEL VARIABLES
Cc = Ac/Vc
OUTPUT1 = Cc # Plasma concentration
