Overview
The present paper introduces a rapid HPLC method for the determination of dioxopromethazine and phenylephrine in eye drops. The method uses a modified C18 stationary phase optimized for the separation of basic compounds and a methanoUl.5 mM phosphoric acid (60/40 v/v, pH 3.02) mobile phase. The flow rate is set to 2 mUmin, sample volume 20 pl, and compounds are detected at 275 nm. Prior to analysis, the eye drops are diluted with water in a rado of 1:50. The elaborated HPLC method and the chromatographic systém esere validated according to the procedure for the validation of chromatographic systems and methds.
