Analysis of lacosamide Levels in blood and saliva in relation to dosage and genotype. (A, B) The linear correlation was shown between BSA-normalized daily dose of lacosamide (mg/m2/day) and its concentration in (A) blood (n = 86) and (B) saliva (n = 109), respectively. (C) A linear regression model described the relationship between blood and saliva lacosamide levels (n = 74) (Csaliva = 4.932 + 0.652 × Cblood, adjusted R2 = 0.38). (D, E) Boxplots represent the dose-normalized (D) blood (n = 146) and (E) saliva (n = 37) levels of lacosamide across three CYP2C19 genotype group, respectively, with significance determined using the Jonckheere-Terpstra test (blood level: P < 0.001, saliva level: P = 0.029). Dose normalization was calculated as concentration × 300 mg/day/daily dose (mg/day). Data in blood sample were merged with the previous study (Supplementary Table 1). BSA body surface area.
