Abstract

A rapid and simple micellar liquid chromatographic method that does not require use of specific chromatographic columns has been developed and validated for azithromycin determination. The method uses a Hypersil C18 column at 60 °C, 1-butanol–pH 6.86 phosphate buffer solution–water, 15:25:60 (v/v), containing 0.10 M sodium dodecyl sulfate, as mobile phase, and UV-detection at 215 nm. Different characteristics of the method were validated satisfactorily. The specificity, accuracy, linearity, precision (repeatability), and robustness of the method were demonstrated. The method proved suitable for determination of the azithromycin content of capsules and uncoated tablets.
