Abstract

A novel, sensitive, and specific gradient RP-HPLC method with UV detection is proposed for the simultaneous quantification of multicomponent liquid dosage form. The separation of the three drugs was achieved using a C18 column (250 mm×4.0 mm, 5 μ) as a stationary phase. No preliminary extraction procedure is required for liquid formulations and a very simple extraction procedure is required for tablets and creams. A mixture of two mobile phases was used with gradient time programing at a flow rate of 1 ml/min. Detection was performed by using PDA detector at 270 nm. Phenylephrine HCl (RT=7.705 min), triprolidine HCl (RT=26.510 min) and dextromethorphan HBr (RT=29.166 min) were separated with good resolution in a single chromatographic run of 50 min. Each drug obeys Beer-Lambert's law in the linearity range of 0.080–0.12 mg/ml for dextromethorphan HBr with a correlation coefficient of 0.998, 0.040–0.060 mg/ml for phenylephrine HCl with a correlation coefficient of 0.996, and 0.010–0.015 mg/ml for triprolidine HCl with a correlation coefficient of 0.998. The recoveries for dextromethorphan HBr and phenylephrine HCl were found to be 99.35% and 99.53%, respectively and for triprolidine HCl was 98.88%. Validation results show satisfactory linearity, precision, accuracy and specificity.
