A common simultaneous HPLC method has been developed for the quantification of common analytes used in cough and cold products. The seven analytes acetaminophen, guafenesin, pheniramine maleate, phenylephrine hydrochloride, diphenhydramine, chlorpheniramine maleate, dextromethorphan are separated out. HPLC separation was achieved on a C18 column with a gradient system optimized for all seven analytes with different chemical structures.
