Abstract
The present research work discusses the development of a stability indicating reversed phase LC method for determination of ciprofloxacin hydrochloride as a bulk drug and from formulations. The mobile phase selected was water-acetonitrile-triethylamine 75:25:0.1 (v/v/v) adjusted to pH 4.0 with o-phosphoric acid. The calibration curve of the drug was linear in the range 0.25–15 μg mL−1. The method was accurate and precise with limits of detection and quantitation of 8.01 and 26.7 ng, respectively. Mean percent recovery was 100.71%. The method was used for analysis of ciprofloxacin hydrochloride from pharmaceutical formulations in the presence of its degradation products and commonly used excipients.
