DDMODEL00000298: Executable_sultiame_nonlinear_PK

  public model
Short description:
The model describes the PK of sultiame after administration of three single oral doses of 50, 100 and 200 mg in open-label at four to six weeks interval in 4 healthy volunteers. Serial measurements in plasma, erythrocytes and urines were performed. The plasma maximal concentrations (Cmax) showed striking non-linear disposition of sultiame, with a ten-fold increase while doses were doubled. Conversely, whole blood Cmax increased less than dose-proportionally whilst staying much higher than in plasma. A three-compartment model incorporating a saturable ligand to receptor binding was devised. The model was expressed in terms of differential equations and first-order rate constants of absorption (ka), elimination (ke), association to (kon) and dissociation from (koff) receptors, maximal binding capacity (Btot), apparent central volume of distribution (V2) and erythrocytes’ volume of distribution (V3).
