Abstract
OBJECTIVE To develop a method for determinating the contents of diphenhydramine hydrochloride and ephedrine hydrochloride in nasal drops.METHODS The dual-wavelength spectrophotometric method was used for eliminating matual interference.RESULTS The method was linear and reproducible.The average recovery was 100.29%, RSD=0.82(n=9) for diphenhydramine hydrochloride and 99.92%, RSD=0.90(n=9) for ephedrine hydrochloride respectively.CONCLUSION The method was simple,rapid and accurate.
