Abstract: Objective To improve the quality control standard of lidocaine hydrochloride injection. Methods A method for determination of related substances in lidocaine hydrochloride injection was established. Lidocaine hydrochloride was assayed by HPLC. The chromatographic conditions: C18 chromatographic column was used. The mobile phase was phosphate buffer and acetonitrile (50:50,adjusted to pH 8 with phosphoric acid). The detection wavelength was 254 nm. Results According to the result of method verification, related substances could be examined by HPLC.Lidocaine hydrochloride was assayed by HPLC, which showed excellent linearity at the range of 373.62-3 736.19 μg/ml. The average recoveries were 102.1%(RSD=0.9%). Conclusion The improved standard could be used to control the quality of lidocaine hydrochloride injection.
