Abstract

The goal of this study was to develop and validate a new gradient high-performance liquid chromatography method for the simultaneous determination of isoniazid (INH) and acetylisoniazid (Ac-INH) in human plasma samples. A C18 reversed-phase column was employed for separation followed by UV detection at 266 nm. The calibration involved the use of five concentration levels ranging from 1 to 20 μg mL−1 for both analytes. The developed method was validated using ICH guidelines. The calibration curve was found to be linear with correlation coefficient values (r 2) above 0.9991 and the highest RSD% values for intra-day assays were found to be 6.34 and 2.57% for INH and Ac-INH, respectively. The highest RSD% values for inter-day assays were 9.31 and 10.17% for INH and Ac-INH, respectively. LOD was calculated to be 0.1 and 0.15 μg mL−1 for INH and Ac-INH, respectively. LOQ was calculated to be 0.33 and 0.5 μg mL−1 for INH and Ac-INH, respectively.
