Abstract
A simple, rapid, and validated HPLC method has been developed for simultaneous determination of levamisole hydrochloride and anhydrous niclosamide. A Luna® C‐18 column was used with a mobile phase consisting of acetonitrile–buffer solutions (2∶8, v/v). Quantitative evaluation was performed at 240 nm. The HPLC method is selective, precise, and accurate and can be used for routine analysis of the preparations in pharmaceutical industry quality control laboratories.
