Simulation of Drug Concentration - Multiple Dose

Simulation of Drug Concentration
Multiple Dose
Two Compartment Model

A patient is to receive lidocaine by IV bolus (three doses possible) and a continuous IV infusion to achieve and maintain drug concentrations between 2 and 6 mg/L for 120 minutes. For this patient use parameters value of kel, k12, k21 and V1 of 0.0297 min^-1, 0.091 min^-1, 0.0369 min^-1, and 33.4 L, respectively.

Some Equations

Equation 30.5.1 Loading Dose using V₁

Equation 30.5.2 Maintenance Infusion Rate using V₁ or Clearance

Equation 30.5.3 Drug Concentration after an IV Bolus Dose

Equation 30.5.4 Drug Concentration after an IV continuous Infusion

Version (a) was derived from the Laplace prepared by convolution with roots 0, -α and β. Version (b) was derived by rearranging version (a). In version (c) clearance, CL, replaces V₁ • kel.

Practice problem answers may not be available on occasion. These practice problems may be used for graded homework from time to time. For any given problem set this will probably be for one or two weeks at most. Please try later.
