ABSTRACT
Background : Lacosamide is one of the anticonvulsants used in critically ill patients. This study aimed to suggest appropriate lacosamide dosing regimens in critically ill patients receiving continuous renal replacement therapy (CRRT) via Monte Carlo simulations. Methods : Mathematical models were created using published demographic and pharmacokinetics in adult critically ill patients. CRRT modalities with diferent efuent rates were added into the models. Lacosamide regimens were evaluated on the probability of target attainment (PTA) using pharmacodynamic targets of trough concentrations and area under the curve within a range of 5–10 mg/L and 80.25–143 and 143–231 mg*h/L for the initial 72 h-ther-apy, respectively. Optimal regimens were defned from regimens that yielded the highest PTA. Each dosing regimen was tested in a group of diferent 10,000 virtual patients. Results : Our results revealed the optimal lacosamide dosing regimen of 300–450 mg/day is recommended for adult patients receiving both CRRT modalities with 20–25 efuent rates. The dose of 600 mg/day was suggested in higher efuent rate of 35 mL/kg/h. Moreover, a patient with body weight>100 kg was less likely to attain the targets. Conclusions : Volume of distribution, total clearance, CRRT clearance and body weight were signifcantly contributed to lacosamide dosing. Clinical validation of the fnding is strongly indicated.
