Article Abstract

Objectives: To model bolus dosing, infusion rate, and weaning rate on theoretical serum concentration of midazolam and pentobarbital used in the treatment of refractory status epilepticus (RSE).

Design: One- and two-compartment in silico pharmacokinetic models of midazolam and pentobarbital.

Setting: Not applicable.

Subjects: Not applicable.

Interventions: We compared the model variables used in midazolam and pentobarbital protocols for standard RSE.

Measurements And Main Results: Standard RSE treatment protocols result in steady-state serum concentrations that are 6.2-9.0-fold higher for the one-compartment model and 2.3-4.7-fold higher for the two-compartment model. In the model, not including bolus doses delays the achievement of serum steady-state concentration by 0.5 and 2.7 hours for midazolam and pentobarbital, respectively. Abrupt discontinuation of these medications reduces modeled medication exposure by 1.1 and 6.4 hours, respectively.

Conclusions: Our in silico pharmacokinetic modeling of standard midazolam and pentobarbital dosing protocols for RSE suggests potential variables to optimize in future clinical studies.
