Abstract: | A selective and sensitive spectrofluorimetric method was developed and validated for the determination of amoxapine in human plasma and urine. The developed method is based on labeling with 5‐dimethylaminonaphthalene‐1‐sulfonyl chloride (dansyl chloride) and monitoring at 397 nm (excitation)/514 nm (emission). The method was validated for linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, recovery and robustness. The calibration curves were linear over a concentration range of 250–2500 and 50–1250 ng/mL for plasma and urine, respectively. The LOD values were calculated to be 13.31 and 13.17 ng/mL for plasma and urine, respectively. The proposed method was applied to study of amoxapine in human plasma and urine.
