DESCRIPTION: PK model
  Simple linear one compartment PK model with 1st order absorption.
; =============================================

  [LONGITUDINAL]

  input = {ka,CL,Vc,Tlag1}
; =============================================
PK:

  ; Model compartments
  ; ------------------
  compartment(cmt=1, amount=Ad)
  compartment(cmt=2, amount=Ac)

  ; Model dosing
  ; ------------
  iv(cmt=1, type=1, p=1, Tlag=Tlag1)

  ; Transfer and elimination definitions
  ; ------------------------------------
  transfer(from=1, to=2, kt=ka)
  elimination(cmt=2, k=-(-(CL/Vc)))

  ; Output variables
  ; ----------------
  Cc = Ac/Vc

OUTPUT:
; =============================================

  output = {Cc}
