This study examines the correlation between the dose of clobazam (CLB) and its serum concentration in adult and pediatric patients, both with and without enzyme inducers. In adults without inducers, the serum concentration showed a strong correlation (y=804.1x, R²=0.87, r=0.75, p<0.001), while adults with inducers also exhibited significant correlation (y=349x, R²=0.79, r=0.65, p<0.001). Pediatric results indicated varying correlations depending on the presence of inducers. Results demonstrate the influence of dosing and enzyme inducers on CLB serum levels.
