Abstract

A high-performance liquid chromatographic (HPLC) assay was developed for the determination of chlorpromazine in serum and human breast milk. Chlorpromazine in serum and human breast milk was extracted by a rapid and simple procedure based on C18 bonded-phase extraction, and a reversed-phase HPLC separation technique was developed. Chlorpromazine and levomepromazine as the internal standard were detected by ultraviolet absorbance at 254 nm. Determination was possible for chlorpromazine in the concentration range 10-300 ng/ml. The recoveries of chlorpromazine added to serum and human breast milk were 80.1-87.6 and 80.3-84.4%, respectively, with coefficients of variation of less than 10.2 and 7.8%. The method is applicable to drug level monitoring in the serum and human breast milk of patients treated with chlorpromazine.
